RSV Risk in Adults: Ages 50 and Older

Most people think of respiratory syncytial virus (RSV) as a childhood illness, but the same virus can seriously affect adults, too. In fact, RSV rivals the flu in both the severity of illness and cost to older adults. Adults ages 75 and older are at the highest risk of severe RSV illness. Adults ages 50-74 can also be vulnerable, especially if they have chronic health conditions, such as asthma, diabetes, or heart disease. These factors can increase the likelihood of severe RSV illness or hospitalization.
