Nearly a third of 200 blood samples taken in Chelsea show exposure to coronavirus https://www.bostonglobe.com/2020/04/17/business/nearly-third-200-blood-samples-taken-chelsea-show-exposure-coronavirus/

“I think it’s both good news and bad news,” said Dr. John Iafrate.”The bad news is that there’s a raging epidemic in Chelsea, and many people walking on the street don’t know that they’re carrying the virus and that they may be exposing uninfected individuals in their families.”

“On the good-news side, it suggests that Chelsea has made its way through a good part of the epidemic,” he said. “They’re probably further along than other towns.”

“The doctors used a diagnostic device made by BioMedomics, of Morrisville, N.C., to analyze drops of blood. It resembled an over-the-counter pregnancy test and generated results on the street in about 10 minutes.”
