Human metapneumovirus, or hMPV, has risen across the United States this winter and spring, according to recent data published by the U.S. Centers for Disease Control and Prevention (CDC).
The percent of tests positive for hMPV increased 19.6 percent for antigen and 10.9 percent for PCR tests at the start of March, when the virus surged this year, the CDC data shows. Around the same time, the percentage of positive COVID-19 and respiratory syncytial virus, or RSV, stood at 7 percent and 2 percent, respectively.
