WHO Clarifies No Emergency Declared in China Over hMPV Surge

The World Health Organization (WHO) has reassured the public that no emergency has been declared in China despite concerns over a surge in respiratory viruses, including human metapneumovirus (hMPV). Dr. Margaret Harris, a spokesperson for WHO, addressed these concerns in a press briefing on Tuesday in Geneva, stating that the increase in cases is expected during the winter season.

Dr. Harris explained that there has been significant media attention surrounding the respiratory viruses circulating in China, with hMPV being one of the notable pathogens. She highlighted that, according to data from the Chinese Center for Disease Control and Prevention (CDC), the surge involves common viruses such as seasonal influenza, respiratory syncytial virus (RSV), hMPV, and SARS-CoV-2, the virus responsible for COVID-19.

“Seasonal influenza is the most common virus detected, with over 30% test positivity among flu-like cases in late December,” Harris reported.

WHO confirmed that the reported levels of respiratory infections in China are typical for winter and that hospital usage is currently lower than at the same time last year. “There have been no emergency declarations or emergency responses triggered,” she added.

Addressing concerns over hMPV, Harris clarified that it is not a new virus. First identified in 2001, hMPV has been circulating among humans for many years, typically causing symptoms similar to the common cold. While it can lead to more severe disease in vulnerable individuals, such as the elderly and newborns, its mortality rate is extremely low.

“It is not a pathogen that normally leads to deaths in humans, except in the most vulnerable populations,” she stated.

Harris also urged the public to practice preventive measures, emphasizing that lessons learned from the COVID-19 pandemic, such as good hand hygiene, wearing masks, improving ventilation, and avoiding crowded places, can help reduce the risk of infection.
