HMPV infections surging in northern China, but not in the Netherlands
Over the past few weeks, several news sources have reported on a surge in human metapneumovirus (HMPV) infections in northern China. The Netherlands is currently monitoring the spread of human HMPV, with no signs of an unusual surge in infections. The respiratory virus, known for causing mild cold- or flu-like symptoms, has been circulating regularly during winter months, and health authorities have not identified any atypical trends this season.
HMPV, which was first discovered in 2001, has been a known pathogen in the Netherlands and other countries for years. Health experts continue to monitor the virus, particularly in light of reports emerging from northern China, where there has been a reported increase in HMPV infections.
Dutch virologists, including Marion Koopmans, a renowned virologist at Erasmus MC in Rotterdam have stated that there is no cause for concern in the Netherlands, as the virus follows predictable seasonal patterns.
“These are diseases we’ve known for quite some time,” Koopmans told NOS. “We expect the usual seasonal increase in respiratory infections, including HMPV, but so far, we have not observed anything out of the ordinary this year.”
The virus is typically spread through respiratory droplets when an infected person sneezes or coughs, and it can also spread through direct contact, such as hugging, kissing, or touching contaminated surfaces. Symptoms include cough, fever, nasal congestion, and wheezing, which are generally mild. However, in individuals with weakened immune systems, the virus can lead to severe complications like pneumonia.
In addition to HMPV, other respiratory infections like COVID-19 and influenza are also under surveillance in the Netherlands. "We expect an increase in Covid again this winter," Koopmans told NOS. "It fits the pattern that we see every year."
However, “we are not seeing anything unexpected at this point,” Koopmans concluded. “The Netherlands is in a good position to handle the usual seasonal respiratory infections, including HMPV, and there is no indication of an unusual situation.”
Though the Netherlands is not seeing a concerning rise in HMPV infections, global reports have raised questions about the virus’s spread in China, where images on social media have depicted crowded hospitals and overstretched healthcare facilities. The Chinese government has similarly stated that the current outbreak is a typical seasonal increase and is not unusual for this time of year.
Hans Kluge, the director of the World Health Organization’s European branch, also reassured the public, stating that HMPV is a common respiratory virus with mild symptoms. “It’s a fairly common respiratory virus that usually causes relatively mild symptoms like cough, fever, nasal congestion and wheezing,” Kluge said in a post on social media.
