I’m Dr. Zachary Rubin, double board-certified pediatrician and allergist, and every fall I see a rise in RSV cases in my clinic. RSV, or respiratory syncytial virus, is the leading cause of infant hospitalization in the U.S.

At first, RSV might seem like just a cold, but if your baby starts breathing fast, pulling in at the ribs or having trouble feeding, it could be more serious.

The good news? We now have tools to fight back. There are new monoclonal antibody treatments that can help infants fight off the virus, and pregnant moms can even get vaccinated to pass antibodies to their babies before birth.

Be sure to wash your hands, avoid crowded indoor spaces or mask up during surges, and don’t ignore wheezing or labored breathing to keep yourself and loved ones safe during this RSV season.
