Chinese state media reported an increase in human metapneumovirus (HMPV) cases, particularly among children under 14 in northern provinces.

 

Why it matters

 

With multiple viruses currently spreading, including norovirus, flu, COVID-19, and RSV, any new outbreak raises public health concerns similar to COVID-19.

 

HMPV

 

HMPV symptoms include cough, fever, runny nose, sore throat, wheezing, shortness of breath, and rashes. While it generally causes mild illness, it can lead to complications like bronchiolitis, bronchitis, pneumonia, asthma, or ear infections. Children under five and adults over 65 are at higher risk of severe outcomes.

 

According to the Centers for Disease Control and Prevention (CDC), HMPV is most common in late winter and spring and accounts for up to 12 percent of childhood respiratory illnesses. Recovery typically takes a few days to a week, though severe cases may last longer.

 

Preventative measures

 

The CDC recommended handwashing, avoiding face-touching, and staying away from sick individuals to prevent HMPV spread.

 

HMPV vs. COVID-19

 

While HMPV often affects children, COVID-19 poses a greater risk across age groups, especially older adults. HMPV can also cause bronchitis, marked by inflamed bronchial tubes and thick mucus, which may be short-term or chronic.

 

China's response

 

Although monitoring of respiratory illnesses has increased in China, there are no lockdowns similar to those seen during the COVID-19 pandemic.

 

China's foreign ministry spokesperson Mao Ning said on Friday that "Respiratory infections tend to peak during the winter season".

 

"I can assure you that the Chinese government cares about the health of Chinese citizens and foreigners coming to China…It is safe to travel in China,” she added.
