Overview of Respiratory Syncytial Virus (RSV)
RSV is a viral infection caused by a member of the Orthopneumovirus genus in the Pneumoviridae family. The virus includes several types, such as human RSV, bovine RSV, and murine pneumonia virus. Human RSV is categorized into two main subgroups—A and B—which differ primarily due to antigenic changes and mutations in the RSV-G gene, as well as broader genomic differences in the RSV-F gene.
Transmission occurs through respiratory droplets from coughing, sneezing, or close contact like kissing. It can also spread by touching contaminated surfaces and then touching the face. RSV remains viable for several hours on hard surfaces, but for a shorter time on soft materials. Children, particularly those in schools or daycare, are highly susceptible to RSV and often pass it on to household members. Nearly all children experience RSV infection by the age of two.
