The World Health Organization (WHO) spokesperson, Dr. Margaret Harris, has reassured the public that the recent rise in respiratory infections in China, particularly the human metapneumovirus (HMPV), is typical for winter, and no emergency has been declared in the country.

Dr. Harris addressed the concerns surrounding the surge of respiratory viruses, including HMPV, during a press briefing in Geneva on Tuesday. She clarified that while there has been a notable increase in respiratory infections, the levels are within the expected range for the winter season, and hospital utilization is actually lower than it was at this time last year.

“The surge involves familiar pathogens, such as seasonal influenza, respiratory syncytial virus (RSV), HMPV, and even SARS-CoV-2,” Dr. Harris explained. According to data from the Chinese Center for Disease Control and Prevention (CDC), seasonal influenza was the most common virus detected, accounting for over 30% of test positivity among flu-like cases by late December.

Dr. Harris emphasized that these respiratory infections are common during colder months and that HMPV, first identified in 2001, is a known virus that generally causes symptoms similar to the common cold. While it can lead to more severe illness in vulnerable populations, such as newborns and the elderly, the mortality rate for HMPV is very low.

“There have been no emergency declarations or emergency responses triggered,” Dr. Harris confirmed, urging the public to remain calm. She also reassured that, like with other respiratory illnesses, simple preventive measures such as hand hygiene, wearing masks, improving ventilation, and avoiding crowded spaces can significantly reduce the risk of transmission.

Addressing the broader concerns, Dr. Harris explained that while HMPV is a part of the natural seasonal pattern, it typically does not pose a significant threat to the general population. The WHO continues to monitor the situation and encourages all individuals to take basic precautions to stay healthy.
