The Centers for Disease Control says a new survey found that 54% of people who tested positive for Covid-19 couldn’t pinpoint how they contracted the virus. The remaining 46% of respondents could recall having close contact with a person — commonly a family member or coworker — who was also diagnosed with Covid-19.
Officials with the CDC said these findings are “very concerning,” and suggest that people are likely contracting Covid-19 from people in their community who are asymptomatic, Dr. Joshua Barocas, infectious disease physician and assistant professor at Boston University School of Medicine, said.
