Preventing Respiratory Syncytial Virus infections

As the winter weather approaches, so does the “sick season,” including illness due to RSV (Respiratory Syncytial Virus). RSV typically starts in fall, peaks in winter, and causes cold symptoms including runny nose, cough, and fever in children and adults. Most kids have had RSV by age 2.

Although usually mild, RSV can cause more serious problems like wheezing, pneumonia, and trouble breathing. These problems are more likely in premature babies or in kids with heart disease, lung issues like asthma, and immune system problems. Between 58,000 and 80,000 kids under age 5 are hospitalized due to RSV each year. Adults aged 60 and above are also at higher risk of more severe RSV illness. Reinfections with RSV are common.
