Similarities between widespread chilly and hMPV

Is hMPV and the widespread chilly the identical? No, the widespread chilly and human metapneumovirus will not be the identical although they share some similarities.

1. Respiratory viruses

This virus, in addition to the viruses that trigger the widespread chilly, each majorly have an effect on the respiratory system.
