As a Pediatrician, I often see a rise in respiratory infections during the colder months. Among these, influenza (flu) and respiratory syncytial virus (RSV) are two of the most common culprits. While both affect the respiratory system, they have distinct symptoms, risks, and preventive strategies. Here’s what every parent needs to know to help keep their children safe and healthy this winter.
What Is Influenza (The Flu)?
Influenza is a highly contagious viral infection that targets the upper and lower respiratory tracts. While anyone can get the flu, it tends to be more severe in young children, the elderly, and individuals with underlying health conditions.
The Best Defense: The annual flu vaccine is the most effective way to protect against severe influenza infections. If your child does catch the flu, prescription antiviral medications like oseltamivir (Tamiflu) can help shorten the illness when started within the first 48 hours of symptoms.
Signs and Symptoms of the Flu:
- Sudden fever
- Chills
- Dry cough
- Sore throat
- Runny or stuffy nose
- Muscle or body aches
- Headaches
- Fatigue
- Occasional vomiting or diarrhea (more common in children)
The flu typically lasts about a week but can lead to complications in high-risk children. Always monitor symptoms closely and consult your pediatrician if concerns arise. For more on influenza, visit the CDC’s Flu Information.
What Is RSV?
RSV is a common respiratory virus that usually causes mild, cold-like symptoms. However, for infants and young children, RSV can escalate quickly and lead to bronchiolitis (inflammation of small airways) and pneumonia. In fact, RSV is one of the most common reasons for hospitalization in children under one year of age.
Did You Know? Each year, 1-3% of U.S. children under one are hospitalized due to RSV. While most cases are manageable at home, severe cases may require oxygen, IV fluids, or other treatments.
Signs and Symptoms of RSV:
- Runny nose
- Cough
- Sneezing
- Fever
- Wheezing or difficulty breathing (e.g., rapid breaths, flaring nostrils)
- Poor appetite
- Lethargy or irritability
When to Seek Help: If your child has difficulty breathing, wheezing, or persistent high fever, seek medical attention immediately. For more, visit the CDC’s RSV page.
The Role of Vaccination in Prevention
One of the most effective ways to prevent influenza and RSV is through vaccination.
Influenza Vaccine: The flu vaccine is recommended annually for everyone aged six months and older. It is especially vital for young children, older adults, pregnant women, and individuals with chronic health conditions, as these groups are at higher risk of severe complications from influenza. The CDC provides comprehensive information about the flu vaccine, including types of vaccines and vaccination schedules CDC – Influenza Vaccination.
Vaccination for Pregnant Mothers
To bolster the defenses of newborns, the CDC recommends that pregnant women receive the RSV vaccine during their pregnancy, ideally between the 32nd and 36th week. This vaccination strategy helps transfer immunity to the baby, providing critical protection against RSV during their first few months of life when they are most vulnerable.
Alongside the RSV vaccine, pregnant mothers should also receive the flu vaccine. Studies have shown that flu vaccination during pregnancy can protect infants against influenza in their early months as well as reduce the risk of preterm labor. More information about vaccinations during pregnancy can be found at CDC – Vaccines During Pregnancy.
Beyfortus (Nirsevimab) for RSV: As of 2023, Beyfortus has emerged as a preventative treatment for RSV, for all infants who will be under 8 months old during the peak season for RSV (generally October through March) whose mothers were not vaccinated against RSV during pregnancy or if the vaccine was given to the mom less than 14 days prior to delivery. It is not a vaccine but rather a monoclonal antibody that protects against infection but does not give long term immunity. Administered as a single intramuscular dose as early as the newborn period, it offers significant protection against severe RSV disease that can last up to six months to protect them during the peak months of illness. It is also recommended for infants under the age of 2 year who are at high risk of RSV complications, including those born prematurely or with certain health conditions. For more detailed information on Beyfortus, please refer to CDC – RSV Prevention.

Everyday Tips to Prevent Flu and RSV
In addition to vaccines, here are practical steps to protect your family:
- Hand Hygiene: Teach kids to wash hands with soap for at least 20 seconds or use alcohol-based sanitizer.
- Avoid Close Contact: Keep children away from anyone who is sick.
- Cover Coughs and Sneezes: Encourage kids to use tissues or their elbows—not their hands!
- Clean Surfaces: Regularly disinfect toys, doorknobs, and light switches.
- Monitor Symptoms: If your child starts showing flu or RSV symptoms, act early and consult your pediatrician.
Why This Matters
Influenza and RSV can have a serious impact on children, particularly in the winter months when these viruses are at their peak. Vaccinations and simple preventive measures remain your best tools to keep your little ones safe.
