HMPV Cases Surge: April Peak Expected

Cases of the human metapneumovirus (HMPV) are experiencing a notable surge across Georgia and other states, with national positivity rates exceeding five percent for the week ending March 7, 2026. This figure is higher than the 3.82 percent recorded during the first week of March 2025. Wastewater testing in Northern California also indicates rising levels of the virus, serving as an early warning system.

HMPV, first identified in 2001, typically circulates during winter and spring, but unlike influenza, its peak often occurs later, with studies suggesting an April peak. While infection usually presents with cold-like symptoms lasting a week, it can escalate to more severe issues such as asthma attacks or middle ear infections. Experts note that HMPV can be more severe than milder viruses like rhinovirus, depending on an individual's health status.

Preventing HMPV infection relies on established public health recommendations, as no vaccines are currently available. The Centers for Disease Control and Prevention (CDC) advises regular handwashing, cleaning frequently touched surfaces, and staying home when ill. These measures are crucial for limiting the spread of HMPV, which transmits through direct contact, respiratory droplets, and contaminated surfaces.
