Respiratory syncytial virus and its impact on the NHS
Respiratory syncytial virus (RSV) is a common virus that causes mostly mild respiratory symptoms. However, for higher-risk groups such as very young children and older adults with chronic diseases RSV infection can be serious or even fatal. Measures introduced to prevent the spread of coronavirus also changed the typical seasonal pattern of RSV infection in 2020 and 2021, leading the NHS to adapt its response.
