RSV, Flu, and COVID: Understanding the Differences Between These Common Respiratory Illnesses

As respiratory viruses spread, many parents are left wondering how to distinguish between RSV, flu, COVID-19, and the common cold. The Children's Clinic in Jackson, TN, is here to help families navigate these illnesses and ensure your child receives the best possible care. Here's an overview of the symptoms, when to seek medical attention, and tips for prevention.

Recognizing Symptoms of Common Respiratory Illnesses

Each illness has unique characteristics, but many symptoms overlap. Here's a quick breakdown:

  • Flu Symptoms
    Fever, chills, headache, body aches, dry cough, fatigue, stuffy nose, and sore throat. Some children may also experience vomiting or diarrhea. Symptoms typically appear 1 to 4 days after exposure.

  • COVID-19 Symptoms
    Fever, cough, fatigue, muscle or body aches, congestion, shortness of breath, sore throat, headache, sneezing, vomiting/diarrhea, or loss of taste or smell. Symptoms can emerge 2 to 14 days after exposure.

  • Cold Symptoms
    Fever, cough, fatigue, stuffy nose, sore throat, sneezing, and slightly swollen glands. Colds, caused by various viruses, are common in children, who may experience 6-10 colds annually.

  • RSV Symptoms
    Fever, cough, fatigue, stuffy nose, shortness of breath, sneezing, rapid breathing, flaring nostrils, wheezing, grunting, poor feeding, or lack of appetite. Symptoms often peak on days 3-5 and can last 7-14 days.

When to Call Your Pediatrician

Some symptoms require immediate medical attention. Contact The Children's Clinic in Jackson, TN, if your child exhibits any of the following:

  • Rapid breathing, flaring nostrils, or grunting

  • Chest caving in with each breath

  • Shortness of breath or difficulty breathing

  • Vomiting for more than 24 hours

  • Bloody diarrhea

  • Severe lethargy or drowsiness

  • Poor feeding or signs of dehydration

  • Fever above 104°F in any child, above 100.4°F in an infant under 2 months, or above 103°F for more than 24 hours.

Can Children Be Infected With Two Viruses at Once?

Yes, co-infections are possible. For instance, children can have both the flu and COVID simultaneously. Secondary illnesses, such as bronchiolitis, pneumonia, ear infections, or sinus infections, are also common. If symptoms overlap, your pediatrician may recommend testing to confirm a diagnosis.

How to Protect Your Family

Preventive measures are key to keeping children healthy. The Children's Clinic in Jackson, TN, emphasizes the importance of immunizations and other protective practices.

  • Vaccinations

    • Flu Vaccine: Recommended annually for everyone 6 months and older.

    • COVID-19 Vaccine: The updated vaccine is recommended for everyone 6 months and older.

    • Nirsevimab (RSV Immunization): For babies under 8 months during their first RSV season and high-risk children aged 8-19 months entering their second RSV season.

    • RSVpreF (RSV Vaccine for Pregnant Individuals): Protects infants from RSV.

  • Hygiene and Masking
    Teach children to cover their mouths when sneezing or coughing and dispose of tissues immediately. Encourage regular handwashing with soap and water or the use of alcohol-based hand sanitizer. Masks can also help reduce the spread of germs in public spaces.
