RSV: 9 Things Parents Should Know

3. RSV is spreading earlier this year than it did in past years. 

RSV typically appears from late spring to early fall, but this year it arrived about four weeks earlier than usual, per the CDC. “We saw fewer cases of RSV in 2020, when many people wore masks due to the COVID-19 pandemic,” Dr. Gagliardo says. Cases began increasing nationwide in spring 2021 when masking guidelines were relaxed.

4. It can be hard to tell RSV apart from other viruses. 

RSV most often causes a cold, which is a type of upper respiratory infection that brings a fever (100.4 degrees Fahrenheit or higher), cough, congestion, runny nose, sneezing, fussiness or poor feeding. A cold may be followed by bronchiolitis, a type of lower respiratory tract infection that brings cold symptoms plus fast breathing, flaring of the nostrils, head bobbing with breathing, rhythmic grunting during breathing, belly breathing or wheezing.

5. RSV symptoms last for five to seven days on average. 

RSV spreads just like the common cold—from one person to another. It spreads through person-to-person contact and through unclean hands or objects. Symptoms can appear two to eight days after contracting RSV. “People with RSV are typically contagious for between three to eight days,” says Dr. Gagliardo.

6. RSV symptoms are typically at their worst from Day 3 – Day 5. 

You should call the doctor if your child has any symptoms of bronchiolitis, dehydration (less than one wet diaper every eight hours for infants), pauses or difficulty breathing, significantly decreased activity and alertness, or develops a grey or blue color on the tongue, lips or skin. Also call a doctor if your child’s symptoms don’t improve after seven days or when your child’s temperature rises above 104 degrees Fahrenheit repeatedly. Children younger than 12 weeks of age should see a doctor anytime their temperature goes above 100.4 degrees Fahrenheit.

7. There is no cure for RSV. 

Medications like steroids and antibiotics do not help. To help your child feel more comfortable, treat RSV’s symptoms similar to the way you’d treat a cold. Use nasal saline with gentle suctioning to allow for easier breathing and feeding. Use a cool-mist humidifier in your child’s room. Keep your child well hydrated. “If your child is older than 6 months, you may use acetaminophen or ibuprofen to help with low-grade fevers,” Dr. Gagliardo says. Never give young children aspirin or cough-and-cold medicines.

8. There is no vaccine for RSV. 

Pfizer and other manufacturers are working on developing RSV vaccines, but they won’t be available for at least another year. In the meantime, you can prevent RSV by washing your hands, keeping your child up to date on their other vaccines (including Tdap and COVID-19), limiting your child’s exposure to crowds, disinfecting objects and surfaces in your home regularly, and feeding your baby breastmilk.

9. RSV may return quickly.

Children and adults can get RSV multiple times—even during the same season. However, repeat infections are often less severe than the first one. The best news: “Most children recover well from RSV and grow into healthy adults,” Dr. Gagliardo says.
