A Centers for Disease Control and Prevention (CDC) study found that nine percent of 1,098 participating pregnant individuals had COVID-19. The findings highlighted the importance of vaccinations for pregnant people since there is growing evidence that pregnancy can produce severe illness from COVID-19.
The study, a collaboration of the CDC with several partners, including Abt Associates, followed a cohort of pregnant individuals from August 2020 through March 2021 at three sites: New York City, Salt Lake City, and Birmingham. AL. The participants sent in weekly nasal swabs regardless of symptoms, completed weekly symptom questionnaires, and submitted additional swabs when they had COVID-like symptoms. An estimated 35 percent of infections were asymptomatic.
“This finding underscores the potential risks of SARS-CoV-2 transmission from pregnant individuals with asymptomatic infection to others in their households and community and the potential risks for horizontal transmission to their newborns,” the study said.
The study found that living with a child age five-17 years increased the risk of infection. Living with a child younger than five did not increase risk. And there was no difference in risk if one telecommuted or worked on site.
