Human Respiratory Syncytial Virus (RSV) has a significant role in the development of newborns' and children's' respiratory tract illnesses. It causes serious lower respiratory tract infections in newborns and young children. RSV causes widespread outbreaks of illness each year during the winter season. in the winter months of November through March RSV outbreaks reach their peak in July, with 55-77% of cases primarily affecting children under the age of four. RSV can spread as cell-to-cell transmission also. The infection of RSV is localized only in the lung. The pathological findings of RSV infection are same as other respiratory infections. RSV is a primary viral infection, and treating it with antibiotics has no effect, But it can help the patients to escape from secondary bacterial infection. Currently, no medication is capable of completely curing RSV. As a result, taking preventative measures is preferable than treating individuals who have a high risk of complications.
