Human Respiratory Syncytial Virus also called as RSV is responsible for causing infection of the respiratory system. It is one of the main reasons for hospitalizations in infants and children due to respiratory system infections. This infection spreads annually in temperate zones in the winters whereas in the tropical zones this spreads in the rainy season. In USA, about 50% of infants are infected with this virus in their first year of life itself and as much as all children at least once have been infected by this virus by the time they are three years of age. There are some cases in children suffering from RSV where they have developed bronchial infection and needed to be hospitalized. Severe infections have also been found in young adults with symptoms resembling that of a common cold. RSV belongs to the virus family of Paramyxoviridae. This family also includes viruses that cause mumps and measles.
