A notable increase in Human Metapneumovirus (HMPV) cases has been reported in northern China, sparking concerns reminiscent of the early COVID-19 pandemic. While videos of overcrowded hospitals circulate on social media, experts assert that HMPV typically causes mild respiratory symptoms. The World Health Organization confirms the virus has been known for years and is being monitored by regional health authorities. Chinese officials downplay the situation, emphasizing that respiratory infections peak during winter. Viroloog Marion Koopmans indicates there is insufficient data to determine the severity of the outbreak.
