Fri Jan 10 13:16:09 UTC 2025: ## WHO Says Rise in Respiratory Infections, Including HMPV, Follows Seasonal Trends

**Geneva, Switzerland/Ahmedabad, India —** The World Health Organization (WHO) has confirmed a rise in acute respiratory infections across the Northern Hemisphere, including cases of human metapneumovirus (HMPV). However, the WHO stressed that this increase is consistent with typical seasonal patterns and not indicative of an unusual outbreak.

The surge in infections is attributed to the seasonal epidemics of various respiratory pathogens, such as influenza, respiratory syncytial virus (RSV), and HMPV, as well as mycoplasma pneumonia. The co-circulation of multiple viruses during winter months can sometimes place a greater burden on healthcare systems, the WHO noted.

While HMPV is a common respiratory virus circulating in many countries during winter and spring, not all countries routinely monitor and report data on its prevalence. Most HMPV infections cause mild cold-like symptoms, but some cases can lead to more severe illnesses like bronchitis or pneumonia requiring hospitalization.

These findings are echoed by health officials in several countries. The Gujarat, India health minister, Rushikesh Patel, confirmed the presence of HMPV in the state and announced the release of a public advisory. At least three confirmed cases have been reported in Gujarat, including an eight-year-old boy currently hospitalized. Similar reports of increased respiratory illnesses, including HMPV, have emerged from China, although the WHO clarified that these are within expected seasonal ranges and have not overwhelmed the Chinese healthcare system.

Health experts worldwide are emphasizing the importance of preventative measures such as frequent handwashing, avoiding close contact with sick individuals, and staying home when unwell. They also stress that HMPV, while causing concern due to increased cases, is not a novel virus and is not comparable to the COVID-19 pandemic. Most individuals develop immunity by childhood.

While some areas are seeing a rise in cases and implementing monitoring committees (such as Chhattisgarh, India), the overall message from health authorities is one of reassurance. The increase in respiratory infections, including HMPV, is considered part of the normal seasonal cycle, and existing healthcare systems are prepared to manage the situation. The WHO advises against any travel or trade restrictions related to these infections.
