Recently, an increase in cases of human metapneumovirus (HMPV) has been observed in northern China, which has caused worldwide concern. Although this situation bears monitoring, experts say that HMPV does not pose a threat comparable to that of Covid-19.
A surge in cases in China
HMPV is a respiratory infection that causes symptoms similar to a cold or flu, but can also lead to serious complications, such as bronchitis or pneumonia, especially in older adults, young children and adults. immunocompromised individuals. This virus is part of the same family as respiratory syncytial virus (RSV) and was first identified in the Netherlands in 2001. Epidemics mainly occur during cold seasons.
The increase in HMPV cases in northern China has attracted attention, especially on social media. However, Chinese health authorities, such as the Center for Disease Control (CDC), have denied rumors of an out-of-control epidemic and overcrowded hospitals. Experts say the apparent increase in cases is partly due to technological advances that make it easier to detect the virus than before.
Chinese Foreign Ministry spokesperson Mao Ning said respiratory infections, such as those caused by HMPV, are common in winter and this season cases are less severe and spread on a smaller scale. . She also stressed that there is no indication of a threat comparable to that of Covid-19.
Risks associated with HMPV
Dr Jacqueline Stephens, from Flinders University in Australia, explains that increased vigilance due to the Covid-19 pandemic explains this disproportionate concern: “ Everyone is extremely attentive and the term ‘human metapneumovirus’ can seem alarming. »
-The symptoms of HMPV are similar to those of a cold or flu, making it one of many so-called “common cold” viruses. According to Dr Stephens, this virus is not one of the notifiable diseases, unlike Covid-19 or the flu. Although these infections are unpleasant for a few days, they are usually not serious and go away with rest and basic care.
HMPV can become more serious for older adults, young children, and people with weakened immune systems. Professor Paul Griffin, infectious diseases specialist in Brisbane, emphasizes the importance of awareness: “ Although there is no vaccine or antiviral drugs to treat HMPV, public information is essential to limit its transmission. »
A controllable phenomenon but to be monitored
Despite the increase in cases in China, experts emphasize that HMPV does not pose a pandemic threat on a global scale. The virus, although it can cause unpleasant symptoms, has been known for several decades and there is some level of immunity in the world’s population due to past infections. Covid-19, on the other hand, was a completely new disease, resulting in a global pandemic.
According to Mr. Griffin, even if a pandemic is not envisaged with this virus, the increase in cases merits remaining vigilant, especially in the absence of vaccines or antiviral treatments. It remains important to take precautionary measures during the winter season: staying home when sick, practicing coughing and sneezing etiquette, and washing your hands frequently.
