Nearly a third of 200 residents in Chelsea show exposure to coronavirus

Nearly one third of 200 Chelsea residents who gave a drop of blood to researchers on the street this week tested positive for antibodies linked to COVID-19, a startling indication of how widespread infections have been in the densely populated city.

Sixty-four residents had antibodies that the immune system makes to fight off the coronavirus.The 200 participants generally appeared healthy, but about half told the doctors they had had at least one symptom of COVID-19 in the past four weeks.

Wearing masks and maintaining social distance are very important. Because you don’t know who is spreading the virus.
