While pregnant women generally experience mild coronavirus symptoms, they can persist for two months or more for 1 in 4 women, according to a study published Wednesday in the journal Obstetrics and Gynecology.
Researchers from the University of California San Francisco and UCLA looked at 594 women across the US who tested positive for Covid-19 while pregnant. They found that 40% of the women still had symptoms by week four, and 25% experienced symptoms for eight weeks or longer.
The most common symptoms among the women were cough, sore throat, body aches and fever, and symptoms were most prevalent in the first three weeks. The median length of symptoms was 37 days. The vast majority of participants – 95% – were not hospitalized.
The participants were enrolled in the study between March 22 and July 10 of this year. More than half of the women had contact with someone who tested positive for Covid-19 or had symptoms. About 30% of the women were health care workers, and 60% were White.
The researchers acknowledged that their findings may not generalize to the larger population. They noted that availability, timing and accuracy of testing may have impacted the results.
COVID-19 symptoms during pregnancy can last a long time, and have a significant impact on health and well being,” study author Dr. Vanessa Jacoby said in a statement.
