RSV Symptoms

RSV infection can cause cold-like symptoms, including a cough and runny nose, which usually last 1 to 2 weeks.

What is the most common cause of RSV?

Respiratory syncytial virus enters the body through the eyes, nose or mouth. It spreads easily through the air on infected respiratory droplets. You or your child can become infected if someone with RSV coughs or sneezes near you. The virus also passes to others through direct contact, such as shaking hands.

Most RSV infections go away on their own in a week or two. There is no specific treatment for RSV infection, though researchers are working to develop vaccines and antivirals (medicines that fight viruses).
