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).
