Some Covid-19 infections among health care workers may be going undetected

Covid-19 among health care providers treating infected individuals may be higher than reported, according to new CDC data. An analysis of more than 3,200 health workers at 13 academic medical centers across the U.S. found that approximately 6% of them tested positive for SARS-CoV-2 antibodies, suggesting they had previously been infected. Yet, almost a third of these individuals did not recall having any symptoms consistent with Covid-19 infection, nearly 1 in 2 didn't suspect having infection, and two-thirds did not have a previous positive test result for Covid-19. Those who said they wore PPE during all interactions with patients were less likely to have SARS-2 antibodies than those who reported inconsistent PPE use.
