The World Health Organization (WHO) has urged countries not to impose travel or trade restrictions in response to the recent outbreaks of Human Metapneumovirus (HMPV) reported in various regions worldwide. Instead, the organization advocates for preventative measures such as wearing masks in crowded or poorly ventilated areas and frequent handwashing to curb the virus’s spread.
In a recent assessment, WHO explained that while HMPV primarily causes upper respiratory infections, it can occasionally lead to severe lower respiratory illnesses such as pneumonia or exacerbate chronic conditions like asthma and chronic obstructive pulmonary disease (COPD). The virus is more active in the winter and early spring, with most individuals exposed to it by the age of five.
Common symptoms of HMPV include cough, fever, sore throat, nasal congestion, wheezing, shortness of breath, and, in some cases, a rash. WHO noted that the virus’s activity tends to coincide with colder months and could add to the burden on healthcare systems already managing the concurrent spread of other respiratory viruses like influenza.
“The concurrent spread of respiratory viruses, including influenza, could place significant pressure on healthcare systems. Individuals should take extra precautions during this period,” WHO warned.
The organization emphasized that people with mild symptoms should remain at home to rest, while those at higher risk or experiencing severe symptoms should seek prompt medical attention. Preventive strategies like covering coughs and adhering to vaccination recommendations from healthcare providers were also strongly advised.
In its disease outbreak update titled ‘Trends of Acute Respiratory Infections’, WHO reported a rise in respiratory infections across the Northern Hemisphere, driven by influenza, respiratory syncytial virus (RSV), and mycoplasma pneumonia. The report highlighted high influenza activity in Europe, parts of Asia, and the Americas, with RSV trends varying by region.
“Robust surveillance systems are essential,” the WHO reiterated, recommending measures such as vaccination, wearing masks in crowded spaces, practicing good hand hygiene, and staying home when unwell to mitigate the overlapping effects of respiratory infections during peak seasons.
WHO pledged to continue monitoring global respiratory illness trends and provide timely updates. The organization also highlighted that in China, where respiratory infections have increased, the trend aligns with typical seasonal patterns. The China Centre for Disease Control and Prevention noted that influenza remains the leading cause of respiratory infections in the country, with HMPV and RSV also contributing to the rise.
The WHO’s call for heightened vigilance and public health measures comes amid efforts to mitigate the impact of overlapping respiratory infections during this critical period.
