What is RSV?
RSV is the most common respiratory illness that causes infections in the respiratory tract (lungs, nose and throat). According to the Centers for Disease Control and Prevention (CDC) almost all children will have an infection before the age of 2. Most cases cause mild, cold-like symptoms, but in some cases, it can be severe and possibly require hospitalization.

“RSV poses a higher risk for severe infection and complication in infants, especially premature infants, young children with congenital heart disease or chronic lung disease and children with weakened immune systems,” Dr. Felman said. “It can cause serious problems, such as pneumonia, and trigger symptoms in children with asthma.”

The virus spreads through the air – either by coughing or sneezing – direct contact or on surfaces like counters, handles, children’s toys and even clothes. “The virus can survive several hours on hard surfaces,” Dr. Felman said. “If your child touches their eyes, nose or mouth after touching an object that has the virus particles on it, they may become infected.”
