Washington, April 4 (RHC)-- The National Academy of Sciences in the United States warns the coronavirus appears to be able to spread through aerosolized droplets.  The finding could invalidate a CDC recommendation that people who stand six feet apart are protected from the virus, with research suggesting that infected people can spread the virus simply by talking or breathing.  

In related news, the Food and Drug Administration has approved a test that screens for antibodies in the blood of people who’ve recovered from exposure to the novel coronavirus.  This comes as hospitals in New York City and in Houston, Texas, have begun experimental convalescent serum therapy for critically ill COVID-19 patients.  The procedure involves harvesting antibodies from the blood of people whose immune systems have beaten the disease.
