Respiratory syncytial virus (RSV) is a negative sense, single stranded RNA virus, member of Pneumoviridae family, Orthopneumovirus genus. It is spread by direct contact with infectious sections or by self-inoculation after touching contaminated surfaces. The virus infects the ciliated epithelial cells of the respiratory tract triggering an intense inflammatory response. | |||

Overview
Respiratory syncytial virus (RSV) is a negative sense, single stranded RNA virus, member of Pneumoviridae family, Orthopneumovirus genus. It is spread by direct contact with infectious sections or by self-inoculation after touching contaminated surfaces. The virus infects the ciliated epithelial cells of the respiratory tract triggering an intense inflammatory response.
Transmission
- Respiratory syncytial virus is spread by
- The virus infects the ciliated epithelial cells of the respiratory tract, specifically the bronchioles. It may also infect the basal cells, targeting the airway epithelium[3].
- Upon infection, an intense inflammatory response is triggered, mediated initially by the infected airway epithelial cells[4][5].
Genetics
- RSV is an enveloped, negative sense, single stranded RNA virus. It is member of Pneumoviridae family, Orthopneumovirus genus[5].
- The viral genome encodes 11 proteins. The G protein is responsible for viral attachment to cells, and the F protein promotes syncytia formation[4].
