China’s health authorities reported on Sunday that the number of infections from the flu-like human metapneumovirus (HMPV) is on the decline. The announcement comes amid global concerns over a surge in cases in northern China.
Wang Liping, a researcher at the Chinese Center for Disease Control and Prevention (CDC), reassured the public that HMPV is not a new virus. It has been circulating among humans for several decades, with the virus first identified in the Netherlands in 2001. The rise in cases in recent years is attributed to improved detection methods rather than a new strain of the virus.
According to Wang, the rate of positive HMPV cases is fluctuating, but there has been a noticeable decline in infections in northern provinces. Furthermore, the number of positive cases among children aged 14 and below has started to decrease.
Gao Xinqiang, deputy director of the Department of Medical Emergency Response of the Health Commission, also addressed concerns regarding rising patient numbers in fever clinics and emergency departments. While there has been an increase in patients, the figures remain lower than the same period last year. Gao emphasized that there has been no significant shortage of medical resources.
HMPV is a common respiratory virus that causes mild cold-like symptoms, although it can lead to more severe conditions in infants and those with weakened immune systems. The virus typically accounts for 4-16% of acute respiratory infections worldwide, with cases peaking between November and May. While most adults have developed immunity through past exposure, the virus can cause complications for vulnerable populations.
Recently, unverified images circulating online showed overcrowded hospitals in northern China, fueling concerns about a potential outbreak. However, the World Health Organization (WHO) has stated it has not received any reports of unusual outbreaks in China or other countries.
Experts note that, unlike the coronavirus, HMPV has been present in human populations for decades, and many individuals have built-in immunity. Most children are exposed to the virus by the age of 5. There are currently no vaccines or specific treatments available for HMPV.
As HMPV cases continue to decline in China, health officials are urging the public to remain vigilant, particularly during the peak respiratory infection season from November to May.
