Some key molecules used by the new coronavirus to cause infection aren’t found in the placenta, which may explain why the virus is rarely detected in fetuses or newborns of women with COVID-19. U.S. government researchers found that placental membranes lack the messenger RNA (mRNA) molecule required to make the ACE2 receptor. SARS-CoV-2 — the…  read on >

It’s the Holy Grail for containing the spread of coronavirus, but contact tracing only works if it is done quickly, researchers report. The modeling study showed that even if all contacts are successfully traced, a delay of three days or more between the start of symptoms and testing will not reduce transmission of the virus…  read on >
