CENTRAL ILLINOIS -- Flu season is in full swing and that has many parents on the look out for another disease.
RSV is a contagious viral disease that may infect a person's lungs and breathing passages.
RSV is present year-round but cases typically goes up in the fall, peak in the winter and decrease in early spring.
The most common cases are found in the youngest of patients.
"Typically in children, a lot of children will have it by the time they are two years old. But many times they recover from it, like most viruses, within one to two weeks," Melinda Cooling of the OSF Saint Francis Medical Group.
Premature infants are twice as likely to be admitted to the hospital for RSV-related symptoms compared with infants born at full term.
What are the symptoms of RSV?:
* Coughing or wheezing that does not stop
* Fast or troubled breathing
* A fever (especially if it is greater than 100.4°F in infants under 3 months of age)
* A bluish color around the mouth or fingernails
* Spread-out nostrils and/or a caved-in chest when trying to breathe
* Gasping for breath
