Who is at most risk of developing severe illness from RSV infection?
The very young (under 1 year of age) and the elderly are at the greatest risk. While most RSV infections usually cause mild illness, infants aged less than 6 months frequently develop the most severe disease (bronchiolitis and pneumonia), which may result in hospitalisation. Children born prematurely, or with underlying chronic lung disease, and the elderly with chronic disease are also at increased risk of developing severe disease.
