CDC: Parvovirus B19 infections on the rise

The U.S. Centers for Disease Control and Prevention reported increased cases of parvovirus B19.

The prevalence of parvovirus B19 — a common and seasonal respiratory virus — declined during the COVID-19 pandemic, according to an article published in CNN. However, case numbers have since begun to rise. For instance, the proportion of Americans with antibodies against parvovirus B19 during the pandemic was less than 3% compared with 10% in June 2024.

The agency detailed that the virus spreads most frequently through close contact with children in schools and daycare centers, where the disease is transmitted via respiratory droplets.

The CDC noted that Americans should watch for symptoms of infection, such as fevers, muscle aches, malaise, facial rashes, body rashes and joint pain.

Although a majority of Americans who contract the disease may be asymptomatic, the CDC stressed that some — including those who are pregnant or have sickle cell disease — may be at high risk of serious infections and complications like severe fetal anemia and aplastic anemia, respectively.

There is currently no vaccine for parvovirus B19, but symptoms typically resolve on their own. The agency suggested that Americans should wash their hands regularly, clean common surfaces, cover their nose and mouth when they cough or sneeze and wear a mask to avoid infection.
