The HMPV seasonal outbreak in China, caused by respiratory syndrome human metapneumovirus (HMPV), began with an increase in cases in Beijing, China in December 2024.. It was brought to public attention when the Chinese Center for Disease Control and Prevention published data showing that respiratory infections of human metapneumovirus had risen significantly in the week of 16 to 22 December ...
Human metapneumovirus (HMPV or hMPV) is a negative-sense single-stranded RNA virus of the family Pneumoviridae and is closely related to the avian metapneumovirus (AMPV) subgroup C. It was isolated for the first time in 2001 in the Netherlands by using the RAP-PCR (RNA arbitrarily primed PCR ) technique for the identification of unknown viruses ...
Human metapneumovirus (HMPV) was first classified as a pneumovirus in 2001. It is a negative-strand RNA virus that is the second most common cause of lower respiratory infection in young children. Pneumoviruses are intermediate in size between viruses of the families Paramyxoviridae and Orthomyxoviridae .
Human metapneumovirus is a leading cause of acute respiratory infection, according to the American Lung Association. As with RSV, most humans have been infected with HMPV by age 5.
Typically, a virus will reach the lungs by traveling in droplets through the mouth and nose with inhalation. There, the virus invades the cells lining the airways and the alveoli . This invasion often leads to cell death either through direct killing by the virus or by self-destruction through apoptosis .
