China is experiencing a surge in cases of human metapneumovirus (HMPV), but medical experts say the situation is less worrisome than it was when Covid-19 emerged five years ago. While HMPV has been circulating in humans for decades, its recent outbreak is notable due to the increase in cases among children.
Here’s what we know about HMPV:
* It is a common respiratory virus that causes mild symptoms, similar to those associated with flu and Covid.
* Most infections are mild, but severe cases can lead to bronchitis or pneumonia, particularly among infants, older adults, and immunocompromised individuals.
* The virus spreads through droplets, aerosols, direct contact, and contaminated surfaces.
* There is no vaccine against HMPV, but research is underway to find a vaccination that could protect against both HMPV and respiratory syncytial virus (R.S.V.).
* Treatment focuses on managing symptoms, not antiviral treatment.
China’s authorities have acknowledged the rise in cases, emphasizing that HMPV is a known entity and not a major concern. They have set up a monitoring system to track pneumonia of unknown origin and urge people to take precautions such as washing their hands frequently and avoiding crowded places.
Medical experts caution that while the situation is less severe than Covid-19, it’s essential for China to share data on the outbreak in a timely manner, including epidemiologic data and genomic data confirming HMPV is the culprit. The World Health Organization (W.H.O.) has not expressed concern, citing predictable rise in cases during the Northern Hemisphere winter.
Overall, while HMPV is a public health concern, it’s essential to separate it from Covid-19 and recognize that the situation is more contained.
