Human metapneumovirus, or HMPV, is making headlines as it surges in northern China and other countries around the world. While the virus is causing concern, public health officials are urging calm as HMPV is typically a mild illness that has been circulating for decades. Despite its prevalence, many people are not familiar with this common respiratory virus.
What is HMPV and should we be worried about it? HMPV is a virus that causes cold and flu-like symptoms, such as coughing, fever, a runny nose, wheezing, sore throat, shortness of breath, and a rash. While most individuals experience mild symptoms, HMPV can progress to more severe conditions like bronchitis or pneumonia, especially in the elderly, young children, and those with preexisting lung conditions or weakened immune systems.
There is no specific vaccine or medication for HMPV, but treatments like oxygen therapy, intravenous fluids, and steroids may be administered to those with severe symptoms. The virus spreads through respiratory droplets from coughing and sneezing, as well as close contact with contaminated surfaces. Practicing good hygiene, such as frequent handwashing, covering your mouth and nose when coughing or sneezing, and avoiding close contact with individuals displaying cold symptoms, can help prevent the spread of HMPV.
In the United States, HMPV has been documented for decades and tends to be more prevalent during the colder months. Recent data from the Centers for Disease Control and Prevention shows an increase in positive HMPV tests towards the end of 2024, indicating a rise in cases during the current season.
While HMPV is causing concern, experts emphasize that it is not likely to lead to a pandemic like Covid-19. The virus is not classified as a notifiable disease, meaning it does not require reporting to health authorities. Improved monitoring technology may be contributing to the higher rates of HMPV cases in certain regions, rather than a particularly severe season.
As with other respiratory illnesses, individuals can protect themselves and others from HMPV by following standard hygiene practices. This is especially important for vulnerable populations who are at higher risk of developing severe symptoms. By staying informed, practicing good hygiene, and seeking medical attention if needed, we can help mitigate the impact of HMPV and other seasonal viruses on public health.
