What causes RSV?
RSV is a type of respiratory virus that can cause infections of the lungs and respiratory tract.
How does RSV spread?
Similar to some other respiratory infections, a cough or sneeze can easily spread RSV. And while you’re typically contagious for 3-8 days, some people, especially those with weakened immune systems, can be contagious for as long as 4 weeks—even after they stop showing symptoms.
When is RSV season?
The seasonality of RSV can vary. Factors such as geographic location, population density, or even climate can impact RSV activity. But for the majority of the United States, RSV cases tend to:
- Rise from mid-September to mid-November
- Peak from late December to mid-February
- Decline from mid-April to mid-May
