When does RSV infection occur, and who gets it?

Infection with RSV is seasonal. In temperate climates, RSV infections usually occur during the late fall, winter, or early spring months. Annual community outbreaks of RSV infection often last four to five months. The winter season (November through April) tend to be most likely to experience RSV epidemic disease. For unknown reasons, severity of illness and frequency of disease often alternate on an annual basis. For example: a "bad" year (large number of patients with moderately severe disease) is followed by a "good" year (fewer number of patients with less severe disease).

More than half of all infants are exposed to RSV by their first birthday. Many have few or mild symptoms. However, some babies with RSV become very ill. RSV is the most common cause of bronchiolitis and pneumonia among infants and children under 1 year of age.

After childhood, RSV causes repeated infections throughout life. These infections are usually associated with cold-like symptoms. However, severe lower respiratory tract disease (for example, wheezing and/or pneumonia) may occur at any age, especially among the elderly or among those with compromised cardiac, pulmonary, or immune systems.

Who is at risk for severe disease?

Several broad categories of patients are most vulnerable to RSV infection. These include: (a) premature infants and all infants less than 1 year of age, (b) children 2 years old with cardiac disease or chronic lung disease (for example, asthma, cystic fibrosis, etc.), (c) those of any age with a compromised immune system, and (d) those 65 years of age or older.
