Human respiratory syncytial virus,illustration
Human Respiratory syncytial virus (HRSV). Illustration showing the inner structure and RNA. This orthopneumovirus,a type of paramyxovirus,is a cause of human respiratory tract infections. It consists of RNA (ribonucleic acid) genetic material enclosed in a protein coat,or capsid,within a phospholipid envelope. The envelope is covered in protein spikes,which enable the virus to attach to and enter a host cell. In adults,HRSV only affects the upper respiratory tract,but in infants bronchiolitis (bronchiole inflammation) or bronchopneumonia can result.
