Large genetic study finds novel coronavirus strain more contagious - WION
A study to understand the structure of the novel coronavirus released on Wednesday has noted that a new strain of the deadly virus is more contagious.
A study to understand the structure of the novel coronavirus released on Wednesday has noted that a new strain of the deadly virus is more contagious. The research conducted by Houston Methodist Hospital examined 5,000 genomes from the viruses recovered in the beginning phase of the outbreak in Houston, US and from a current wave of infections.

The spikes are what lead to binding the virus to other cells, thereby severing the infection. It, however, needs to undergo a review by the peers. The researchers said the variant strain had substantial amounts of the Covid-19 on initial diagnosis. The study also noted that in some regions there were many mutations, possibly hinting that the virus is changing its order to counter the body's immune system. The research is also seen as the largest collection of genetic sequences of the virus in the US so far.
Doctors claim coronavirus can be contacted in womb after baby born with virus in US - WION
The baby reportedly developed fever and breathing difficulties which are the first signs of coronavirus and tested positive 24 to 48 hours later, reports claimed.
A girl was born in Texas with coronavirus even as her mother was diagnosed with COVID-19 with doctors claiming that the infection can be transmitted in the womb.

The baby reportedly developed fever and breathing difficulties which are the first signs of coronavirus and tested positive 24 to 48 hours later, reports claimed. After treatment with supplemental oxygen, the tests remained positive but 21 days later both mother and baby recovered and were sent home. Earlier, newborn triplets in Mexico had tested positive for coronavirus even though doctors claimed that the parents hadn't contracted the virus. However, doctors had suspected that the triplets could have got infected in the womb through the mother's placenta during pregnancy. Experts earlier hadn't ruled out the transmission of the virus from the mother's placenta during childbirth. The World Health Organization(WHO) had said last week that new mothers infected with coronavirus should generally continue breastfeeding and should not be separated from their babies. WHO chief Tedros Adhanom Ghebreyesus said: "We know that children are at relatively low-risk of COVID-19, but are at high risk of numerous other diseases and conditions that breastfeeding prevents," while adding," based on the available evidence, WHO's advice is that the benefits of breastfeeding outweigh any potential risks of transmission of COVID-19." The WHO chief's view was seconded by another WHO official Anshu Banerjee who said that mothers with suspected or confirmed coronavirus should be encouraged to initiate and continue breastfeeding and not be separated from their infants. US health authorities had earlier issued an alert over autoimmune condition among children that is believed to be linked to coronavirus. T The US Center for Disease Control and Prevention (CDC) had said that multisystem inflammatory syndrome in children (MIS-C) involved fever, inflamed organs causing severe illness which often required hospitalization.
