What is RSV Disease?
RSV is a virus that infects the lungs
- RSV or respiratory syncytial [sin-sish-uhl] virus is a contagious viral disease that may infect a person's lungs and breathing passages
- Most children will catch RSV by the age of 2 years
- RSV spreads rapidly among children. While most will recover in 1 to 2 weeks, even after recovery, infants and children can continue to spread the virus for 1 to 3 weeks
Most people recover from the disease in a week or two, but in premature infants or those with lung or heart problems, severe RSV disease can lead to serious lung infection and hospitalization
- RSV is present year-round but typically goes up in the fall, then peaks in the winter and goes down in early spring. But, the exact timing of RSV season varies by location
