Human metapneumovirus is a common respirt (Placeholder1)ory pathogen that affects people of all ages,but is especially prevalent in young children.In 2001,human metapneumovirus was first identified in Netherlands causing clinical symptoms in childern,however serological studies demonstrated that pathogen was already circulating in Netherlands in1958. The complete sequence of the hMPV genome has been elucidated .As the preliminary sequence data for the hMPV genome suggested,the virus is member of the Metapneumovirus genus, a branch of family Paramyxoviridae,and is genetically similar to,through distinct from,the avian pneumovirus at earierly it known as turkey rhinotracheitisvirus.hMPV is the major etiological agent responsible for about 5% to 10% of hospitalizations of children suffering from acute respiratory tract infections.The virus shows toxicity in a vulnerable population, including small children, elderly persons and immunalvanized patients, where it can cause severe infection of the lower respiratory tract. Clinical manifestations range from mild upper respiratory symptoms to serious complications such as bronchiolitis and pneumonia, with special ideas requiring a high-risk population. This review explores the virology, epidemiology, clinical features, diagnostic approaches, treatment options, and prevention strategies for hMPV.
