Rare syndrome linked to COVID-19 found in 600 U.S. children: CDC - CANOE

Nearly 600 children were admitted to U.S. hospitals with a rare inflammatory syndrome associated with the novel coronavirus over four months during the peak of the pandemic, the Centers for Disease Control and Prevention (CDC) said in a report on Friday. Multisystem inflammatory syndrome (MIS-C) is a rare but severe condition that shares symptoms with toxic shock and Kawasaki disease, including fever, rashes, swollen glands and, in severe cases, heart inflammation. It has been reported in children and adolescent patients about two to four weeks after the onset of COVID-19. With rising COVID-19 cases, there could be an increased occurrence of MIS-C, but this might not be apparent immediately because of the delay in development of symptoms, said the report’s authors, including those from the CDC’s COVID-19 response team. In May, the CDC published a health advisory with details of how MIS-C manifests in patients, and asked clinicians to report suspected U.S. cases to local and state health departments. As of July 29, state health departments across the country reported a total of 570 MIS-C patients diagnosed with the illness from March 2 to July 18. Among the MIS-C cases, all patients tested positive for COVID-19 and 10 died, the CDC said in the report. The data is consistent with two U.S. studies published in June and several reports of the syndrome among COVID-19 patients in France, Italy, Spain and Britain. The report, the CDC said, highlights the need for greater awareness among healthcare providers, as distinguishing patients with MIS-C from those with acute COVID-19 and other hyperinflammatory conditions is critical for early recognition, early diagnosis, and prompt treatment.
Widespread mask-wearing could prevent COVID-19 second waves: Study - CANOE

LONDON — Population-wide facemask use could push COVID-19 transmission down to controllable levels for national epidemics and could prevent further waves of the pandemic disease when combined with lockdowns, according to a UK study published Wednesday. The research, led by scientists at the Britain’s Cambridge and Greenwich Universities, suggests lockdowns alone will not stop the resurgence of the new SARS-CoV-2 coronavirus, but that even homemade masks can dramatically reduce transmission rates if enough people wear them in public. “Our analyzes support the immediate and universal adoption of facemasks by the public,” said Richard Stutt, who co-led the study at Cambridge. He said the findings showed that if widespread mask use were combined with social distancing and some lockdown measures, this could be “an acceptable way of managing the pandemic and re-opening economic activity” long before the development and public availability of an effective vaccine against COVID-19, the respiratory illness caused by the coronavirus. The study’s findings were published in the “Proceedings of the Royal Society A” scientific journal. The World Health Organization updated its guidance on Friday to recommend that governments ask everyone to wear fabric face masks in public areas where there is a risk to reduce the spread of the disease. In this study, researchers linked the dynamics of spread between people with population-level models to assess the effect on the disease’s reproduction rate, or R value, of different scenarios of mask adoption combined with periods of lockdown. The R value measures the average number of people that one infected person will pass the disease on to. An R value above 1 can lead to exponential growth. The study found that if people wear masks whenever they are in public it is twice as effective at reducing the R value than if masks are only worn after symptoms appear. In all scenarios the study looked at, routine facemask use by 50% or more of the population reduced COVID-19 spread to an R of less than 1.0, flattening future disease waves and allowing for less stringent lockdowns. “We have little to lose from the widespread adoption of facemasks, but the gains could be significant,” said Renata Retkute, who co-led the study.
