Is It the Flu, COVID, RSV, or Just a Cold? How to Tell the Difference
Your child has a stuffy nose, a cough, and a fever—but is it the flu? COVID-19? Or could it be respiratory syncytial virus (RSV)? With so many overlapping symptoms, it can be tough to figure out what’s making your little one feel under the weather.
At the Children’s Clinic in Jackson, TN, we see many cases of viral respiratory illnesses, and while they share similar symptoms, there are some key differences that may help you identify what’s going on.

When to Call Your Pediatrician
While most viral illnesses can be managed at home with rest, fluids, and symptom relief, you should seek medical attention if your child experiences:
Rapid breathing, wheezing, or nasal flaring
Chest caving in with each breath
Severe shortness of breath or difficulty breathing
Vomiting lasting more than 24 hours
Bloody diarrhea
Extreme fatigue or appearing very ill
Poor feeding or signs of dehydration (dry mouth, no tears when crying, fewer wet diapers)
Fever above 104°F in any child
Fever above 100.4°F in infants under 2 months old
Fever above 103°F lasting more than 24 hours
Can a Child Be Infected with Multiple Viruses at Once?
Yes. It’s possible for children to have both the flu and COVID-19 at the same time, or to develop a secondary infection like bronchiolitis, pneumonia, or an ear infection. Because symptoms of viral infections often overlap, your pediatrician may order a test to confirm the diagnosis if needed.
How to Reduce the Risk of Illness
The best way to protect your child from severe illness is through routine vaccinations and healthy hygiene habits.
Recommended Immunizations
Flu Vaccine – Recommended yearly for everyone 6 months and older. Get vaccinated early to stay protected throughout the flu season, which can last until late spring.
COVID-19 Vaccine – Recommended for everyone 6 months and older. Ask your pediatrician when your child should receive the updated vaccine.
RSV Immunization (Nirsevimab) – Recommended for babies under 8 months old during their first RSV season and for some high-risk children up to 19 months old.
RSV Vaccine (RSVpreF) – Recommended for pregnant individuals to help protect newborns from RSV.
Additional Ways to Stay Healthy
Teach kids to cover their mouth and nose with a tissue or elbow when sneezing or coughing.
Wash hands frequently with soap and water, or use hand sanitizer when soap isn’t available.
Consider wearing a mask in crowded indoor spaces during cold and flu season.
