UP hospital worker dies day after getting Covid-19 vaccine: Officials reveal actual cause of death - TheHealthSite
As many as 447 adverse events were reported in the first two days of the vaccination programme including serious cases that required hospitalization.
As India enters the third day of the nationwide Covid-19 vaccination drive on Monday, reports of adverse events following immunization (AEFI) are coming up from various parts of the country. According to the Union Health Ministry, as many as 447 adverse events were reported in the first two days of the inoculation programme, including serious cases that required hospitalization.

According to media reports, 46-year-old ward boy Mahipal Singh died after complaining of chest congestion and breathlessness. However, Moradabad’s chief medical officer MC Garg has clarified that the death is unrelated to Covid-19 vaccination.

On Sunday he felt breathless and complained of chest congestion, but it does not seem to be a reaction to vaccination, Garg had said late Sunday night. Speaking to the media, the man’s son Vishal said his father may have been unwell before the vaccination, but that he felt worse after receiving the shot. According to him, Singh had usual cough and cold, but he started feeling worse after returning home from the vaccination centre. He was feeling breathless and he was coughing, Vishal told media. In a press release, the Uttar Pradesh government said that it vaccinated 22,643 people on Saturday, the first day of India’s Covid Vaccination drive. Majority of adverse events are minor: Health ministry Earlier, news agency IANS reported that a 22-year-old security guard at All India Institute of Medical Sciences (AIIMS), New Delhi, was admitted in the intensive care unit (ICU) after he developed an allergic reaction post vaccination. The guard experienced headache, rash, respiratory distress, and tachycardia. A healthcare worker of NDMC Charak Pallika Hospital was also hospitalised post inoculation in the hospital, the Delhi government had revealed on Saturday. The person was, however, discharged after few hours of observation. A total of 2,24,311 beneficiaries received Covid vaccines in 553 sessions of vaccination till Sunday across the country, according to the Union Health Ministry. The ministry also stressed that majority of the adverse event following immunisation are minor in nature such as pain, mild swelling at injection site, mild fever, body ache, nausea, giddiness and mild allergic reactions like rashes, etc.” These may or may not be related to the vaccination process, it said.
Covid-19 may eventually resemble the common cold in future, scientists predict - TheHealthSite
COVID-19 may resemble the mild cold-causing coronaviruses that currently circulate in humans if it becomes endemic and most people are exposed in childhood.
A new study published in the journal Science suggests the SARS-CoV-2, the virus that causes COVID-19 may resemble the mild cold-causing coronaviruses that currently circulate in humans if it becomes endemic and most people are exposed in childhood. Also Read - Pregnant women, minors will not get Covid-19 vax in Maharashtra Trajectory Of Covid-19 As It Becomes Endemic The researchers noted that four common cold-causing coronaviruses have been circulating in humans for a long time and almost everyone is infected at a young age. Also Read - Should you get a shot if youve already had COVID-19? Heres what experts say According to the author of the study, natural infection in childhood provides immunity that protects people later in life against severe disease, but it doesn’t prevent periodic reinfection. Also Read - Gut microbiome imbalances influence the likelihood of long Covid Covid-19 May Become An Early Childhood Disease The research suggests that endemic SARS-CoV-2 may become a disease of early childhood, where the first infection occurs between 3 and 5 years old, and the disease itself would be mild. The study stressed that older individuals could still become infected, but their childhood infections would provide immune protection against severe disease. Vaccines May Reduce The Severity Of The Disease How fast this shift comes depends on how fast the virus spreads and what kind of immune response the SARS-CoV-2 vaccines induce. The researchers suggest that if the vaccines induce short-lived protection against becoming reinfected but reduce the severity of the disease, as is the case with other endemic coronaviruses, SARS-CoV-2 may become endemic more quickly. “This model assumes immunity to SARS-CoV-2 works similar to other human coronaviruses. We don’t really know what it would be like if someone got one of the other coronaviruses for the first time as an adult, rather than as a child, one of the researchers was quoted as saying. Fatality Rates May Wane In The Near Future The model predicts that the infection fatality ratio for SARS-CoV-2 may fall below that of seasonal influenza (0.1 per cent), once an endemic steady-state is reached. “We are in uncharted territory, but a key take-home message from the study is that immunological indicators suggest that fatality rates and the critical need for broad-scale vaccination may wane in the near term,” said Ottar Bjornstad, a professor, and epidemiologist at Penn State. He noted that maximum effort should be on weathering this virgin pandemic enroute to endemicity. Maximum Effort Should Be On Weathering This Pandemic To Endemicity A safe and effective vaccine against COVID-19 could save hundreds of thousands of lives in the first year or two of vaccine roll-out, but continued mass vaccination may be less critical once SARS-CoV-2 becomes endemic, the researchers said. Targeted vaccination in vulnerable subpopulations may still save lives, they said. The researchers also noted that if primary infections of children are mild when the virus becomes endemic, widespread vaccination may not be necessary. However, if primary infections become severe in children, as in the case of more deadly but contained coronaviruses such as MERS, childhood vaccinations should be continued, the added. “Herd Immunity Unlikely Amid Vaccine Roll Out” The World Health Organizations chief scientist warned that even as numerous countries start rolling out vaccination programs to stop COVID-19, herd immunity is highly unlikely this year. At a media briefing on Monday, Dr. Soumya Swaminathan said it was critical countries and their populations maintain strict social distancing and other outbreak control measures for the foreseeable future.
Pandemic triggering dramatic hair loss; Tips to tackle the problem - TheHealthSite
People are experiencing major hair loss due to the coronavirus pandemic. Read on to know how you can combat the problem and get rid of the hair fall.
Unearthing clumps of hair in your shower drain is never a pretty sight! Hair fall may not be harmful, but it is scary. While shedding approximately 50 to 100 strands each day is normal, losing more hair than usual could be a cause of concern. Also Read - Nasal Covid vaccine can be potential gamechanger: Experts In the current scenario, people have been experiencing a host of seemingly distinct symptoms, including episodes of hair loss. But it can be confusing for healthy individuals to understand the exact cause of the problem. As it turns out, one thread that connects it all is chronic stress. But coronavirus patients may also experience hair loss after getting infected. Also Read - 76% of COVID patients have at least one symptoms 6 months after the infection: Study Hair Loss Following COVID Infection Dr Sirisha Singh, Dermatologist, explains, Hair goes through a growth cycle. Hair can be in the anagen phase or the growing phase when the hair roots are strong and a telogen phase when hair is typically shed. Also Read - Covaxin volunteer dies after 10 days; Bharat Biotech says death not related to vaccine trials The condition, referred to as the telogen effluvium, is a form of temporary hair loss usually happens after a shock or a traumatic event. With people losing their jobs, unable to see their families and going through a tough time naturally, these drastic lifestyle changes led to an overwhelming amount of stress. Following any stress to the body, including a COVID infection, waves of hair may go into the telogen phase, and there may be significant shedding of hair. This typically starts about 2-3 months after the COVID infection and may last for 6-9 months. Following this, people usually notice a gradual recovery, she added. Stress-Induced Hair Fall The symptom may even appear in people who have never had coronavirus, which can be extremely confusing for many. It turns out that chronic stress could be the reason behind involuntary shedding of your hair. Some hair shedding may be inevitable, but stress can add to the problem. In addition, if a person has poor nutrition or suffers from a deficiency, the problem may get aggravated, elaborated Dr Singh. How Can You Manage Hair Loss? If you have been experiencing hair loss throughout the pandemic, youre not alone. But the good news? Hair loss triggered by telogen effluvium is reversible. Genetic (alopecia) hair loss may be difficult to treat, but this type of hair fall is hormonal, which is why it can be controlled. Here are some ways suggested by the expert to combat the problem.
- Keep stress levels in control. Managing COVID-19 induced stress is vital to stop the hair fall. Hair shedding is most likely reversible, but if you stress, you may worsen the problem
- Look out for nutrition deficiencies and get them treated if required
- Take supplements containing biotin, zinc and certain amino acids and peptides as it may provide benefits. They can slow down hair shedding after 2 months of starting the supplements
- Continue to shampoo and brush your hair as these are not the reasons for hair fall. They will only aggravate the shedding of telogen hair
76% of COVID patients have at least one symptoms 6 months after the infection: Study - TheHealthSite
A new study published in The Lancet has found that more than three-quarters of COVID-19 patients reported at least one ongoing symptom.
Ever since the pandemic took over the world with a storm last year, we all have been aware of the symptoms of COVID-19. But what about post-COVID? Do the symptoms completely disappear, or is there a possibility of experiencing some symptoms after recovery? Also Read - Pandemic triggering dramatic hair loss; Tips to tackle the problem As it turns out, 76 per cent of coronavirus patients have at least one ongoing symptom six months after initially becoming unwell, suggests a study published in the prestigious journal The Lancet. Also Read - Nasal Covid vaccine can be potential gamechanger: Experts Study Aims At Identifying The Long-Term Consequences Of COVID-19 COVID-19, the emerging infectious disease caused by severe acute respiratory syndrome coronavirus 2 or SARS-CoV-2 has resulted in millions of deaths across the globe. Since it first surfaced in Wuhan, China, scientists have been trying to figure out the long-term consequences of the illness. Majority of which remains unclear until now. The study aims at describing the long-term consequences of COVID-19 in patients after hospital discharge and identify the potential risk factors. Also Read - Covaxin volunteer dies after 10 days; Bharat Biotech says death not related to vaccine trials Fatigue And Muscle Weakness Is Most Common According to the Wuhan-based study, more than three-quarters of COVID-19 patients reported at least one ongoing symptom. While 26 per cent of the individuals involved in the study experienced sleep difficulties, and 23 per cent experienced anxiety or depression, 63 per cent were reported to suffer from fatigue and muscle weakness. “Our analysis indicates that most patients continue to live with at least some of the effects of the virus after leaving the hospital, and highlights a need for post-discharge care, particularly for those who experience severe infections,” said Bin Cao, Professor at the Capital Medical University in Beijing, China. For the study, the team involved 1,733 Covid-19 patients who had a median age of 57 years. Follow-up visits were done, and the median follow-up time was 186 days. All patients were interviewed face-to-face using questionnaires to evaluate their symptoms and health-related quality of life. They also underwent physical examinations, lab tests, and a six-minute walking test to gauge patients’ endurance levels. 390 patients had further tests, including an assessment of their lung function. In addition, 94 patients whose blood antibody levels were recorded at the height of the infection as part of another trial received a follow-up test. Patients Also At Risk Of Reduced Lung Function And Kidney Problems According to the study, 41 per cent of the 390 patients tested for lung function experienced reduced lung function. 56 per cent of those with severe illness experienced a reduced flow of oxygen from the lungs to the bloodstream. For patients at severity scale 4 (who required oxygen therapy) and those at scale 3 (who did not require oxygen therapy) the figures were 29 per cent and 22 per cent, respectively. The findings also suggest that patients with more severe disease performed worse in the six-minute walking test. Researchers also found that 13 per cent of the patients whose kidney function was normal while in the hospital had reduced kidney function in their follow-up. Follow-up blood antibody tests from 94 patients after six months revealed that levels of neutralising antibodies were 52.5 per cent lower than at the height of infection. The authors say this raises concerns about the possibility of Covid-19 re-infection. (with inputs from IANS)
Vaccine usage alert for Covid-19: A guide to safely get the coronavirus vaccine shot - TheHealthSite
Scientists have outlined steps on safely receiving the second dose of the Covid-19 vaccination in individuals who develop a reaction to their first dose.
Following accounts of potential allergies to the COVID-19 vaccines produced by Pfizer-BioNTech and Moderna, scientists have outlined steps on safely receiving the second dose of the therapeutic in individuals who develop a reaction to their first dose. Also Read - Covid-19 can wreck your heart: Cardiac issues, including heart attack, rise by 50% during pandemic With the vaccine being administered in many corners of the world, questions abound about who can safely get them. Also Read - COVID-19 Vaccine Covishield gets final approval, ready for rollout in coming weeks Expect answers to those questions to evolve as the vaccines go into broader use. But heres what is known so far, and what experts at or advising the Centers for Disease Control and Prevention recommend regarding their use at this point. Also Read - After 'Covishield', expert panel approves Bharat Biotech's 'Covaxin' for emergency use Can People With Allergies Get The Covid-19 Vaccination Shot? Reports that two nurses in Britain developed anaphylaxis after being immunized with the Pfizer vaccine earlier last month, triggered concerns about whether people with allergies should be vaccinated. Both women had serious allergies and carried EpiPens. In the study, a team of experts led by allergists at Massachusetts General Hospital (MGH) in the US, proposed detailed advice so that individuals with different allergy histories can safely receive their COVID-19 vaccine. After a closer review of the data related to allergic reactions, the US FDA recommended that the mRNA vaccines, based on the genetic material of the novel coronavirus, be withheld only from individuals with a history of severe allergic reactions to any component of the COVID-19 vaccine. However, it is cleared for usage by people who have allergies to foods, animals, insects, latex, and other common allergies. Can Pregnant Women Get Covid-19 Vaccine Shot? The Covid vaccine developed by Pfizer and its partner, BioNTech, hasnt yet been tested in pregnant people in fact, none of the vaccines in development have been. Drug and vaccine makers are always reluctant to include pregnant people in clinical initial trials for fear of injuring a developing fetus or threatening a pregnancy. Can People With HIV Get Covid-19 Vaccination Shot? Pfizer enrolled some HIV-positive volunteers with stable infections in its Phase 2/3 clinical trial, but there are not enough data to date to do an analysis of this population. The CDC said people with HIV can be vaccinated but should be counseled that the safety and efficacy of the vaccine in immunocompromised people are still unclear and they should continue to take other measures to protect themselves against infection. The Mandatory Post Vaccination Observation The US Centers for Disease Control and Prevention also advised that all patients be observed for 15 minutes post-vaccination by staff who can identify and manage such reactions. In the review research, Aleena Banerji, MD, clinical director of the Allergy and Clinical Immunology Unit at MGH, and her colleagues outlined steps on safely receiving the second dose in individuals who develop a reaction to the first dose of COVID-19 vaccine. According to experts, allergic reactions to vaccines are rare, with a rate of about 1.3 per 1 million people. Pfizer-BioNTech And Moderna To Have Low Rate Of Allergic Reactions They said the mRNA vaccines developed by Pfizer-BioNTech and Moderna will have a similarly low rate of occurrence of allergic reactions. The researchers recommend that individuals with a history of anaphylaxis to an injectable drug, or vaccines containing polyethylene glycol or polysorbate speak with their allergists before being vaccinated. The researchers also suggested that vaccine clinics monitor all patients for 15 to 30 minutes to manage any allergic reactions that occur. They said even patients with severe allergies to foods, oral drugs, latex, or venom can safely receive the COVID-19 vaccines. (With inputs from Agencies)
Revisiting popular myths about Covid-19 before 2020 ends - TheHealthSite
When the coronavirus pandemic started spreading its wings rapidly across the globe several myths about the virus started doing the rounds on the internet.
When the coronavirus pandemic started spreading its wings rapidly across the globe earlier this year, several myths about the virus and the disease started doing the rounds on the internet. A lot of false and misleading reports also went viral on social media during the early days the pandemic. As such misinformation further complicated the war against Covid-19, the National Disaster Management Authority (NDMA) in its lockdown order included a warning that those circulating fake news on Covid-19 shall face fine or one-year imprisonment as per Section 54 of the Disaster Management Act, 2005. As researchers and medical professionals uncover more information about the novel coronavirus, they were able to debunk most of these myths and misconceptions that people believed were true.

Drinking alcohol doesnt help prevent coronavirus, but it can be useful to disinfect surfaces, said the WHO. Instead, the UNs health agency recommends people to wash hands often, wear masks, and avoid being close to those with a fever and cough. Myth#3 Covid-19 be transmitted through mosquitoes The virus spreads mainly from person to person in respiratory droplets released while coughing, sneezing or talking. However, there is no evidence that the novel coronavirus can be transmitted through mosquitoes. Myth#4 Covid-19 can be transmitted on goods transported from China The World Health Organisation (WHO) said that although the virus can last on surfaces for many hours, the environment, transportation and varying temperatures during shipment make it difficult for it to remain active. This means the probability of transmission of the virus on goods imported from China is very low. If you feel the surface may be contaminated, clean it with a disinfectant and wash your hands after touching it, said the WHO. Myth# 5 Eating garlic prevent Covid-19 Garlic is commonly used in Ayurveda for treating various diseases and boosting immunity. However, cant prevent you from the deadly COVID-19 virus. The WHO said, Garlic is a healthy food that may have some antimicrobial properties. However, there is no evidence from the current outbreak that eating garlic has protected people from the new coronavirus. Myth#6 Ayurvedic herb giloy can help prevent covid-19 Swami Ramdev Baba had claimed that yoga and Ayurveda can help prevent coronavirus infection. He said that Ayurvedic herb giloy (Tinospora Cordifolia) may help prevent coronavirus. Giloy is known to contain antioxidants which help to detox the body and strengthen your immune system, which may help protect your body against infections. But theres no evidence that the herb can stop entry of coronavirus into the body or kill the virus.
Beware: Sore eyes, light sensitivity may indicate COVID-19 infection - TheHealthSite
A new study argues that it is important to include ocular distress in the list of possible COVID-19 symptoms. Read on to know more.
The COVID-19 virus is predictably unpredictable. It can be quite confusing in the way it manifests itself in people. Since the beginning of the pandemic, we have seen that there are various, often unrelated, symptoms that may indicate infection. This highly infectious viral disease affects different parts of the body. It can attack the organs, like kidneys and lungs, and give rise to secondary health issues. Though a dry cough, breathlessness, fever and body ache are common COVID-19 symptoms, some people may also experience skin rashes, conjunctivitis and diarrhea. A new research has also found that some people may also experience ocular symptoms that may often be confused for some other eye infection. According to researchers at Anglia Ruskin University (ARU), sore eyes are the most significant vision-based indicator of COVID-19. This new study was published in the journal BMJ Open Ophthalmology. Also Read - Covid-19 may trigger recurrent Guillain-Barre Syndrome: Home remedies that can help 18 per cent respondents reported light sensitivity As part of their study, researchers asked people who had a confirmed COVID-19 diagnosis to complete a questionnaire about their symptoms, and how those compared to before they tested positive. The study found that sore eyes was significantly more common when the participants had COVID-19, with 16 per cent reporting the issue as one of their symptoms. Just 5 per cent reported having had the condition beforehand. While 18 per cent of people reported suffering from photophobia (light sensitivity) as one of their symptoms, this was only a 5 per cent increase from their pre-COVID-19 state.

The most common reported symptoms overall were fatigue (suffered by 90 per cent of respondents), a fever (76 per cent) and a dry cough (66 per cent). Also Read - Coronavirus FAQs: Does wearing two masks provide better protection than one? Important to include ocular distress in list of symptoms According to researchers, this is the first study to investigate the various eye symptoms indicative of conjunctivitis in relation to COVID-19, their time frame in relation to other well-known COVID-19 symptoms and their duration. While it is important that ocular symptoms are included in the list of possible COVID-19 symptoms, researchers argue that sore eyes should replace ‘conjunctivitis‘ as it is important to differentiate from symptoms of other types of infections, such as bacterial infections, which manifest as mucous discharge or gritty eyes. This study is important because it helps understand more about how COVID-19 can infect the conjunctiva and how this then allows the virus to spread through the body. (With input from Agencies)
Vaccines expected to reach Delhi by December end: Centre zeroes in on cold storage facility - TheHealthSite
A building in the Rajiv Gandhi Super Speciality Hospital premises has been found suitable by the Centre to be used as a COVID-19 vaccine storage facility.
As the cold chain points across the country are remodelling themselves to support the storage of the upcoming COVID-19 vaccine, the national capital is expected to receive its first batch of vaccines by the end of December, officials of the Rajiv Gandhi Super Speciality Hospital, the first vaccine storage facility in Delhi, told IANS. B.L. Sherwal, medical director of the hospital, said that a separate facility in the hospital has been demarcated to store the vaccine doses which are expected to arrive by the month end. The vaccine doses will arrive at the storage units by the end of December. To store them in Delhi, a building on the campus has been demarcated. This building is currently undergoing refurbishment.

Sherwal informed IANS that the Centre is providing deep refrigerators of different kinds to support the storage temperature of the variety of vaccines which are currently under different stages of clinical trials. The Centre will provide deep refrigerators with storage capacity ranging from -20 to -70-degree Celsius. Besides, model 228, which are regular refrigerators used to store medical drugs, will also be used.

Currently, the hospital is remodelling the electrical points and other infrastructure as per the requirements of the deep refrigerators. The Centre had recently asked the states and Union Territories to review cold storage and refrigerated vans used for the already existing universal immunisation programme. Under the programme, around 28,000 cold chain points are used, along with 700 refrigerated vans. Also Read - Covid-19 vaccines to be available soon, but dont forget handwashing 1 crore healthcare workers to be vaccinated first The Centre has also drawn up a plan under which the first dose of vaccine, whichever candidate is available, will first be administered to 1 crore healthcare workers across the country.

The Pune-based Serum Institute of India, which is testing and manufacturing the Oxford-AstraZeneca candidate, has said that it will apply for emergency marketing authorisation of the vaccine in little over a month’s time. The vaccine being manufactured by it can be stored at temperatures between 2 and 8-degree Celsius. The lowest minimum temperature at which vaccines can be kept to maintain the cold chain in most areas in the country is -25-degree Celsius as there is only one vaccine in India — Bharat Biotech’s Rotavirus vaccine — which needs to be stored at -20-degree Celsius.

Poor air quality 'can worsen' the severity and spread of coronavirus - TheHealthSite
With the toxic air pollution looming over our heads India’s battle against the novel coronavirus is set to face a new range of challenges and hurdles.
With the toxic air pollution looming over our heads, Indias battle against the novel coronavirus is set to face a new range of challenges and hurdles. High air pollution, low temperature, and coronavirus may turn out to be a deadly combination. Also Read - New model to enable drug predictions against COVID-19 developed While COVID-19 has been detected as a serious respiratory illness causing a virus, it is natural to assume that exposure to polluted or toxic air only heightens the risk of serious respiratory diseases. That being said, let us look at this problem in detail. Also Read - Turkey's new virus figures confirm experts' worst fears ILLNESSES CAUSED BY COVID-19 VIRUS Coronaviruses (CoV) are a large family of viruses that cause illnesses ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). Also Read - Building emotional immunity amid Covid 19 scare Common signs of infection include respiratory symptoms, fever, cough, shortness of breath, and breathing difficulties. In more severe cases, an infection can cause pneumonia, severe acute respiratory syndrome, kidney failure, and even death. That being said, the rising pollutants in the air will add more risk to the lives of humans. Inhaling this toxic air can cause serious lung problems. When humanity is already threatened with the COVID-19 virus, inhaling toxic air will fly add more miseries. AIR POLLUTION CAN AMPLIFY COVID-19 CONTAMINATION According to new research, these elevated levels of air pollution may amplify the waves of SARS-CoV-2 contamination, the virus responsible for Covid-19 diseases. The study, published in the journal Earth Systems and Environment, investigated possible interactions between acutely elevated levels of fine particulate matter and the virulence of the coronavirus disease. The result suggests that high concentrations of particles less than 2.5 micrometers in size may modulate, or even amplify, the waves of SARS-CoV-2 contamination and explain in part the particular profile of the Covid-19 pandemic. “The study provides preventive measures related to air pollution to limit future outbreaks of morbidity and mortality due to the coronavirus,” said study author Mario Rohrer from the University of Geneva in Switzerland. SARS-CoV-2 WAS PRESENT IN EUROPE IN 2019 Covid-19 studies conducted in Italy and France suggest that SARS-CoV-2 was already present in Europe at the end of 2019, while the sharp increase in morbidity and mortality was only recorded in spring 2020 in Paris and London. “This time lag is surprising, but also suggests that something else than just the mere interaction of people may promote the transmission of the virus, and particularly the severity of the infection,” Rohrer said. The research team has been able to show that these increases in cases followed phases where the levels of fine particles in the air were higher. The team made similar observations in the Swiss canton of Ticino, where fine-particle pollution increased sharply during a period of shallow fog on the Magadino plain and the Sotto Ceneri, observed at the end of February 2020. HOW DOES AIR POLLUTION AFFECT YOU The findings showed that acute concentrations of fine particles, especially those smaller than 2.5 micrometers, cause inflammation of the respiratory, pulmonary and cardiovascular tracts and thicken the blood. “In combination with a viral infection, these inflammatory factors can lead to a serious progression of the disease. Inflammation also promotes the attachment of the virus to cells,” Rohrer said. Nonetheless, the researchers also emphasize that, although particulate matter pollution can influence the virulence of the virus and possible severe disease progression, physiological, social, or economic factors will clearly also influence the further course of the pandemic. “This study offers the possibility of taking preventive measures in the event of future increases in fine particulate matter concentrations, thus limiting a new flare-up of Covid-19 morbidity and mortality,” the team noted. HOW TO STAY SAFE? As air pollution engulfs various states across the nation, the quality of the air you are proving your lungs with is degrading. Understandably, the toxic air is making everyone cough, causing throat irritation, and even spreading viral infections. Take these small steps to keep you safe.
- Avoid morning walks
- Use good quality masks when outdoor
- Stay hydrated and follow a healthy diet
- Avoid smoking
- Lung cleansing take steam every day as a process of lung detoxification.
Diabetes associated eye disease linked to 5-fold risk of severe Covid-19, study - TheHealthSite
A study linked diabetes retinopathy with an increased risk of requiring intubation when hospitalized with Covid-19. Read on to know more.
People suffering from health conditions like diabetes and eye disease may be at a five-fold increased risk of requiring intubation when hospitalized with Covid-19, according to the finding of a new study. The study published in the international journal Diabetes Research and Clinical Practice found a link between diabetic retinopathy and Covid-19. Also Read - Blood sugar spike due to COVID-19 could kill even non-diabetics Diabetic retinopathy is a common diabetes complication that affects eyes. In the disease, the blood vessels of the light-sensitive tissue in retina get damaged, which may cause blindness if left untreated. Studies have found that people suffering from diabetes are at an increased risk of coronavirus. Also Read - Experts reveal strategies to reduce indoor transmission of COVID-19 The Link Between Diabetic Retinopathy And Severe Covid-19 Infections The research team, including study author Antonella Corcillo from the Kings College London in the UK, studies the effects of diabetic retinopathy on the severity of the viral infection. For the study, the researchers investigated 187 people with diabetes, hospitalized with Covid-19. This included 179 with type 2 diabetes and eight with type 1 diabetes. 36 per cent of the patients had diabetic retinopathy, 26 per cent were intubated. It was also reported that 45 per cent of these patients had retinopathy. Also Read - COVID-19 Live Updates: Cases in India surge to 91,77,840 while death toll reaches 1,34,218 According to the results of the study, patients with diabetic retinopathy were at a five-fold risk of severe Covid-19 infection. Also, 32 per cent of the patients died, and no association was observed between retinopathy and mortality.However, the researchers stated that there is an increasing evidence of significant damage to the blood vessels in the lung and other organs in patients hospitalized with severe Covid-19. People with diabetes are also at a higher risk of vascular complications that affect the large and small blood vessels. Coronavirus And Respiratory Failure The study concluded that vascular diseases, such as diabetic retinopathy, makes people more vulnerable to respiratory failure in severe Covid-19 cases. A study published in The Lancet also found a link between Covid-19 and acute respiratory failure. Respiratory failure is a serious condition that occurs when the lungs dont get enough oxygen into the blood. It leads to a buildup of carbon dioxide and damages the tissues and slows down the oxygen delivery to the tissues. Symptoms of this condition may include:
- Rapid breathing
- Inability to breathe properly
- Skin, fingertips or lips turning blueish
- Irregular heartbeats
- Profuse sweating
- Loss of consciousness
Dog owners more likely to get COVID-19 infection: What can you do? - TheHealthSite
However researchers are not clear whether dogs acted as a host for the virus and transmitted it directly or the owners picked it up indirectly from them.

Therefore, they asked dog owners to take extreme hygiene measures in relation to their pets. Risk factors in COVID-19 transmission In view of the rapid spread of the virus even during lockdown in Spain, the researchers designed a survey to identify the possible routes of transmission of the COVID-19 disease, risk factors, and the effectiveness of the hygiene measures. It included 2,086 individuals from across Spain. They found that people who cohabit with a COVID-19 patient have 60 times higher risk of suffering from COVID-19. Surprisingly, the risk of contracting the disease was up to 78% higher among those living with a dog and taking it for a walk. However, having cats or other types of pets had no significant effect on the prevalence of the disease. In the absence of an effective treatment or vaccine, preventive hygiene measures are the only salvation, noted Cristina Sánchez González, a researcher at the UGRs Biomedical Research Centre and the main author of this work. These measures should also be applied to dogs, as they appear to directly or indirectly increase the risk of contracting the virus, she added. Sánchez González also pointed out that further studies are needed to determine the reasons behind the prevalence of the COVID-19 virus among dog-owners. Can animals spread SARS-CoV-2? Currently, there is limited information on whether animals play a significant role in spreading the virus that causes COVID-19. But the risk of animals spreading COVID-19 to people is considered to be low, according to the US Centers for Disease Control and Prevention (CDC). There have been reports of cats, dogs, and some other mammals being infected with SARS-CoV-2. But most of these pets became sick after contact with people who had COVID-19. COVID-19 infection has been reported in mink farms in the Netherlands, Denmark, Spain, Italy, Sweden, the United States, and Greece. But infected farm workers were believed to be the initial source of the mink infections. Why you should disinfectsupermarket products? The study also noted that disinfecting products purchased from the market once back home can help reduce the risk of possible exposure to COVID-19 virus by 94%. In the survey, a higher prevalence of COVID-19 infection was detected among those who had purchased their basic products at a supermarket and then used the home delivery service. The risk of contracting the virus increased by 94% in this group. Those who brought their shopping home themselves had lesser risk. In addition, the survey found that people working outside the home 76% higher risk of getting the virus, especially those using public transport like the underground system or tram network.
Silent hypoxia: Scientists crack the mystery behind this life-threatening complication of COVID-19 - TheHealthSite
Scientists solve the mystery of ‘silent hypoxia’ one of the biggest and most life-threatening complications of COVID-19.
With the COvID-19 pandemic continuing unabated across the world, scientists are having a tough time trying to solve the many puzzling aspects of how the virus causing the deadly disease attacks the lungs and other parts of the body. One of the biggest and most life-threatening mysteries that emerged is how the virus causes “silent hypoxia,” a condition when oxygen levels in the body are abnormally low. This causes irreparably damage to vital organs over time. But now, thanks to computer models and comparisons with real patient data, Boston University biomedical engineers and collaborators from the University of Vermont have begun to crack the mystery. Also Read - Scientists identify possible COVID-19 treatment for life-threatening complications A dangerous condition that creeps up silently Despite experiencing dangerously low levels of oxygen, many people infected with severe cases of COVID-19 sometimes show no symptoms of shortness of breath or difficulty breathing. Hypoxia’s ability to quietly inflict damage is why it’s been coined “silent.” In coronavirus patients, it’s thought that the infection first damages the lungs, rendering parts of them incapable of functioning properly. Those tissues lose oxygen and stop working, no longer infusing the blood stream with oxygen, causing silent hypoxia. But exactly how that domino effect occurs has not been clear until now.

Some coronavirus patients have experienced what some experts have described as levels of blood oxygen that are “incompatible with life.” Disturbingly, many of these patients showed little to no signs of abnormalities when they underwent lung scans. To help get to the bottom of what causes silent hypoxia, BU biomedical engineers used computer modeling to test out three different scenarios that help explain how and why the lungs stop providing oxygen to the bloodstream. Their research, which has been published in Nature Communications, reveals that silent hypoxia is likely caused by a combination of biological mechanisms that may occur simultaneously in the lungs of COVID-19 patients. Also Read - COVID-19 patients likely to be 'most infectious during first week after symptom onset' Blood vessels constrict in areas of lungs without oxygen Normally, the lungs perform the life-sustaining duty of gas exchange, providing oxygen to every cell in the body as we breathe in and ridding us of carbon dioxide each time we exhale. Healthy lungs keep the blood oxygenated at a level between 95 and 100 per cent — if it dips below 92 per cent, it’s a cause for concern and a doctor might decide to intervene with supplemental oxygen. The researchers first looked at how COVID-19 impacts the lungs’ ability to regulate where blood is directed. Normally, if areas of the lung aren’t gathering much oxygen due to damage from infection, the blood vessels will constrict in those areas. This is actually a good thing that our lungs have evolved to do, because it forces blood to instead flow through lung tissue replete with oxygen, which is then circulated throughout the rest of the body. COVID patients lose ability to restrict blood flow to damaged lung tissue But preliminary clinical data have suggested that the lungs of some COVID-19 patients had lost the ability of restricting blood flow to already damaged tissue, and in contrast, were potentially opening up those blood vessels even more — something that is hard to see or measure on a CT scan.
- Using a computational lung model, researchers tested this theory, revealing that for blood oxygen levels to drop to the levels observed in COVID-19 patients, blood flow would indeed have to be much higher than normal in areas of the lungs that can no longer gather oxygen — contributing to low levels of oxygen throughout the entire body.
- Next, they looked at how blood clotting may impact blood flow in different regions of the lung. When the lining of blood vessels gets inflamed from COVID-19 infection, tiny blood clots too small to be seen on medical scans can form inside the lungs. They found, using computer modeling of the lungs, that this could incite silent hypoxia, but alone it is likely not enough to cause oxygen levels to drop as low as the levels seen in patient data.
- Last, the researchers used their computer model to find out if COVID-19 interferes with the normal ratio of air-to-blood flow that the lungs need to function normally. This type of mismatched air-to-blood flow ratio is something that happens in many respiratory illnesses, such as with asthma patients, and it can be a possible contributor to the severe, silent hypoxia that has been observed in COVID-19 patients. Their models suggest that for this to be a cause of silent hypoxia, the mismatch must be happening in parts of the lung that don’t appear injured or abnormal on lung scans.
