How long after being exposed to rsv?

Symptoms of respiratory syncytial virus (RSV) typically appear within 4-6 days after exposure to the virus. However, the incubation period can range from 2-8 days. RSV is a highly contagious respiratory illness that is spread through contact with respiratory droplets from an infected person. It is most commonly spread during close contact, such as kissing, sharing cups or utensils, or being in close proximity to someone who is coughing or sneezing.
