It takes between two and eight days after being exposed to the RSV for symptoms to appear. Symptoms persist three to seven days on average. The majority of children and adults recover completely within one to two weeks. However, some people may experience complications from RSV infection. Children under five years old are most likely to be infected with RSV. Adults also can be infected, but they are less likely to experience severe illness. People over 60 years old are most at risk of developing serious complications from RSV infection. These problems include pneumonia, heart disease, and kidney failure. Children who have chronic conditions such as asthma or cancer are at greater risk of developing severe illness if they get RSV infection. People who have recently been through a hospital environment where RSV is found in the air should avoid touching anything with moisture on them for several hours after leaving the room. This is important because our hands are how we transport viruses from person to person. Symptoms of RSV infection include: fever, coryza (cold-like symptoms including sneezing, sore throat, and runny nose), muscle aches, loss of appetite, feeling tiredness. In general, the younger you are, the more likely you are to develop serious health problems if you get RSV infection.
