About RSV
– RSV is a virus transmitted by respiratory secretions, and commonly causes upper and lower respiratory tract infection. Repeated infections are common throughout life because natural infection does not confer long-lasting immunity.
– in adults, RSV usually causes upper respiratory tract infection symptoms (cough, sore throat, nasal congestion etc). Lower respiratory tract infection can also cause wheezing and breathing difficulty.
– in children, the first RSV infection usually occurs by 2 years of age.
– The highest burden of RSV disease is among very young children and elderly people.
– RSV is the leading cause of hospitalisation due to lower respiratory tract infection and bronchiolitis in infants aged under 6 months. Most hospitlisations occur in children that are otherwise healthy.
– Hospitalisation rates decline with age after early childhood, then increase again from 50 to 65 years of age.
– Aboriginal and Torres Strait Islander adults have an increased risk of severe disease and hospitalisation due to RSV.
