Human metapneumovirus particles. Coloured transmission electron micrograph (TEM) of particles of the human metapneumovirus (hMPV),a respiratory virus that affects almost all children by the age of 5. The virus is a type of paramyxovirus,consisting of RNA (ribonucleic acid) genetic material enclosed in a protein coat,or capsid,within a phospholipid envelope. The envelope (pale) is covered in protein spikes,which are seen here as the virus' outermost layer (orange). hMPV will only cause a mild respiratory tract infection in healthy adults but small children,elderly and immunocompromised individuals are at risk of severe disease and hospitalisation.
