The HMPV virus (Human Metapneumovirus) is a contagious respiratory virus that can lead to illnesses ranging from mild cold symptoms to severe respiratory distress. It primarily affects young children, the elderly, and individuals with weakened immune systems, often causing symptoms such as fever, cough, and shortness of breath. The virus spreads through respiratory droplets, making it highly transmissible in close-contact environments. While there is no specific antiviral treatment for HMPV virus, most cases resolve with supportive care. However, more serious cases may require hospitalization, especially in vulnerable populations.
