The U.S. Centers for Disease Control and Prevention (CDC) issued a health alert on Wednesday about an increase in human parvovirus B19 infections.
Between 2022 and 2024, only around 3 percent of the U.S. population had immunoglobulin M (IgM) antibodies to parvoviruses, indicating that only that amount of the population had been infected with parvovirus. But in June 2024, the number grew to 10 percent.
