Description and significance
Human Respiratory Syncytial Virus was first isolated in 1956 from a laboratory chimpanzee with a respiratory illness and was later discovered to be of human origin. RSV consists of two antigenic subtypes, A and B. Subtype B is characterized as the asymptomatic strains that of which the majority of individuals experiences. The more severeillnesses and which usually predominate during outbreaks are associated with subtype A strains. RSV was determined to be the leading cause of lower respiratory tract infections particularly in young infants. The severity of the disease is very diverse ranging from mild cold symptoms to severe and life-threatening. It's the leading cause of pneumonia and bronchiolitis in infants. It may cause mortality or morbidity in the elderly as well as immunodeficient individuals. It is the most common pathogen leading to hospitalization in young children up to the age of 5. Approximately two thirds of infants are infected with RSV within their first year and 90% have been infected by the age of 2.
Genome structure
The genome of RSV was completely sequenced in 1997. It is a linear single stranded negative-sense RNA consisting of 15,191 base pairs. The genome is found in the helical nucleocapsid. The genome encodes for 11 proteins including structural and non-structural.
