What is RSV and why does it matter?
RSV (Respiratory Syncytial Virus) is a common virus that can cause cold-like symptoms. But for infants, some young children, and older adults, RSV can be serious. It can lead to hospitalization or other serious health problems. RSV season usually runs from October to March, but timing may vary depending on where you live especially in places like Alaska, Florida, and U.S. territories. If you're in one of these areas, ask your healthcare provider when RSV season starts.
