What Is Respiratory Syncytial Virus (RSV) and Why Is It Dangerous to Infants?
January 20, 2026Respiratory Syncytial Virus, commonly known as RSV, is a widespread respiratory virus that most children are exposed to by the age of two. For many people, RSV causes mild, cold-like symptoms. For infants and young children, however, RSV can be more serious and sometimes life-threatening.
For families in Athens, GA, and surrounding counties and towns, understanding RSV can help parents and caregivers recognize symptoms early and seek timely care.
What Is Respiratory Syncytial Virus (RSV)?
Respiratory Syncytial Virus (RSV) is a highly contagious virus that affects the lungs and breathing passages. It spreads easily through respiratory droplets, close contact, and contaminated surfaces. RSV is especially common during fall and winter months, when respiratory illnesses tend to increase.
Why Is RSV More Dangerous for Infants?
Infants have smaller airways and developing immune systems, which makes it harder for them to fight respiratory infections. RSV can cause inflammation and mucus buildup in the lungs, making breathing difficult.
Infants at higher risk for severe RSV illness include:
- Babies younger than 6 months
- Premature infants
- Infants with chronic lung disease
- Infants with congenital heart conditions
- Infants with weakened immune systems
Common RSV Symptoms in Infants
RSV symptoms may start mild and worsen over several days. Watch closely for:
- Runny nose or congestion
- Coughing or wheezing
- Rapid or labored breathing
- Decreased appetite
- Fever
- Irritability or unusual tiredness
In severe cases, RSV can lead to bronchiolitis or pneumonia, which may require hospitalization.
