Young children, older adults and those with weakened immune systems are at a higher risk of developing severe illness due to HMPV.

Five years after the Covid-19 pandemic China is witnessing an outbreak of the human metapneumovirus (HMPV). According to reports and social media posts, hospitals are overcrowded with infected individuals and crematories are overwhelmed. Some social media users claim that multiple viruses, including influenza A, HMPV, Mycoplasma pneumoniae and Covid-19, are circulating in China. There are even claims that China has declared a state of emergency, however, there's no official confirmation.

HMPV causes flu-like symptoms. The virus usually affects the upper respiratory system but can sometimes cause lower respiratory infections. HMPV is more common in winter and early spring.

Symptoms of the human metapneumovirus

HMPV symptoms are similar to those of flu or common cold. It can spread from an infected individual to others through coughing, sneezing or personal contact. Some common symptoms include:

Cough

Fever

Nasal congestion

Sore throat

Shortness of breath

The estimated incubation period is three to six days and the duration depends on the severity of the infection.

Currently, there is no specific antiviral therapy or vaccine to prevent HMPV.
