News that northern China is seeing a surge of the respiratory illness called human metapneumovirus (HMPV), bringing an uptick in hospitalizations, is sparking a bit of anxious déjà vu on social media.

China is experiencing a surge in infections of a respiratory virus, leading to public concerns about an outbreak. The virus, identified as human metapneumovirus (HMPV), has seen cases spiking across northern Chinese provinces this winter, particularly among children.

The most common symptoms associated with HMPV are nasal congestion, cough, fever and shortness of breath, according to the CDC. In the U.S., the virus typically spreads between the winter and the spring seasons, the CDC indicated on its website.
