Current guidelines for screening U.S. blood donors for symptoms of COVID-19 and for a history of recent infections are effectively protecting the blood supply from contamination with the new coronavirus, researchers say.
Months after recovery from mild Covid-19 – when antibody levels in the blood have declined – immune cells in bone marrow remain ready to pump out new antibodies against the coronavirus, researchers reported on May 24 in Nature. And according to a new U.S. study, young children appear to be significant carriers of more contagious variants of the new coronavirus, such as the ones identified in the UK and in California.
A new study by researchers at the University College London (UCL) published in Lancet Infectious Diseases finds that although the U.K. variant of SARS-CoV-2 known as B.1.1.7 is more transmissible than the wild-type, original Wuhan strain, it is likely not more deadly.

Researchers at Weill Cornell Medicine identified a specific and unique kind of immune cell activity in the lungs of Covid-19 patients that is different from the type of immune cell activity found in other respiratory infections.
