Human metapneumovirus

Human metapneumovirus is a virus that infects the respiratory system and causes illness similar to the common cold or flu, including cough, fever, and congestion. Scientists discovered this virus relatively recently in 2001, and it circulates worldwide, affecting people of all ages though it tends to be more serious in young children, elderly people, and those with weakened immune systems. Like other respiratory viruses, it spreads through droplets when infected people cough or sneeze, and researchers are still studying it to better understand how it spreads and develop more effective treatments.
