What are the symptoms of an RSV infection?

RSV infection causes symptoms similar to a cold. These include: 

• a cough 

• a runny or blocked nose 

• sneezing, and 

• tiredness. 

In some cases, RSV can cause wheezing, shortness of breath or a fever, and may lead to pneumonia (infection of the lungs).
