RSV stands for respiratory syncytial virus. It is a common virus that infects the nose, throat, and lungs.
Who is at higher risk
RSV is often mild, but it can be serious for infants, older adults, people with weakened immune systems, and people with heart or lung disease.
Common symptoms
Symptoms can include runny nose, cough, sneezing, fever, wheezing, reduced appetite, or breathing difficulty. Babies may show poor feeding, irritability, or pauses in breathing.
Fast breathing, blue lips, dehydration, or trouble breathing needs urgent medical attention.
