People infected with RSV usually show symptoms within 4 to 6 days after getting infected. Symptoms of RSV infection usually include

• Runny nose
• Decrease in appetite
• Coughing
• Sneezing

These symptoms usually appear in stages and not all at once.

In very young infants with RSV, the only symptoms may be irritability, decreased activity, and breathing difficulties.

Almost all children will have had an RSV infection by their second birthday.
