With colder weather arriving, respiratory illnesses like RSV (Respiratory Syncytial Virus) become more common. As people spend more time indoors, germs spread more easily, increasing the risk of infections. While RSV is generally mild, it can pose significant risks to infants, young children, and older adults. Understanding RSV, its symptoms, and prevention methods can help keep your family safe this season.
What is RSV?
Respiratory Syncytial Virus (RSV) is a common respiratory virus that affects the lungs and breathing passages. While RSV often causes mild cold-like symptoms, certain groups are at higher risk for severe complications.
Who is Most at Risk?
RSV can infect individuals of any age, but the following groups are at higher risk for severe illness:
- Infants, especially those under 6 months old
- Young children with weakened immune systems or lung conditions
- Older adults, particularly those with chronic health conditions like heart disease, diabetes, or lung disease
- Immunocompromised individuals
Symptoms of RSV in Babies
RSV symptoms in babies can resemble those of a common cold but may worsen. Common signs to watch for include:
- Runny nose
- Coughing
- Sneezing
- Fever
- Decreased appetite
- Irritability and fussiness
- Reduced urination (sign of dehydration)
Severe Symptoms in Infants
In some cases, RSV can lead to serious complications such as bronchiolitis or pneumonia. Watch for these warning signs:
- Wheezing or noisy breathing
- Fast or labored breathing
- Bluish lips or fingernails (sign of low oxygen)
- Lethargy or extreme tiredness
If your baby shows severe symptoms, seek medical attention immediately.
RSV Symptoms in Adults
While RSV symptoms in healthy adults are typically mild, those over 60 or with underlying conditions may face complications. Common symptoms include:
- Runny nose
- Mild cough
- Congestion
- Sore throat
- Mild fever
Severe RSV Symptoms in Older Adults
In vulnerable adults, RSV can cause:
- Shortness of breath
- Chest pain
- Severe coughing fits
- Worsening of chronic conditions
RSV Complications and Risks
RSV can sometimes lead to severe respiratory conditions such as:
- Bronchiolitis: Inflammation of small airways in the lungs
- Pneumonia: A serious lung infection
- Asthma Flare-ups: RSV may worsen asthma symptoms in affected individuals
When to Seek Medical Care
For infants, call a doctor if you notice:
- Difficulty breathing
- Severe coughing
- Refusal to drink fluids
- Signs of dehydration
For adults, immediate medical care is necessary if there is:
- Persistent wheezing or chest pain
- Difficulty breathing
- Symptoms that worsen over time
RSV Treatment Options
Most RSV cases resolve on their own within one to two weeks. Treatment typically includes:
- Over-the-counter medications to reduce fever and pain
- Saline drops or nasal suction to clear nasal congestion in infants
- Hydration to support recovery
- Rest to boost immune response
In severe cases, hospitalization may be required to provide oxygen therapy, intravenous fluids, or breathing support.
RSV Vaccination and Prevention
RSV Vaccines for Adults
The CDC now recommends RSV vaccines for adults aged 60 and older. Two single-dose vaccines are available, designed to reduce the risk of severe illness.
Maternal RSV Vaccine
For pregnant women, the CDC and ACOG recommend the RSV vaccine during the 32-36 week mark of pregnancy. This vaccination helps pass protective antibodies to the unborn child, offering protection during the initial months of life.
RSV Preventive Measures for Everyone
To minimize the risk of RSV, follow these preventive steps:
- Practice Good Hygiene: Wash your hands frequently with soap and water for at least 20 seconds.
- Avoid Close Contact: Refrain from kissing or touching infants, especially when feeling unwell.
- Disinfect Surfaces: Clean frequently touched objects like toys, doorknobs, and countertops.
- Cover Coughs and Sneezes: Use a tissue or your elbow to reduce germ spread.
- Limit Exposure: Keep sick children home from daycare or school to prevent outbreaks.
How RSV Spreads
RSV spreads through:
- Direct contact with contaminated surfaces
- Respiratory droplets from coughs or sneezes
- Touching your face after contacting virus-infected objects
Managing RSV at Home
If your child or family member has mild RSV symptoms, these home care strategies can help:
- Use a cool-mist humidifier to ease breathing
- Ensure proper hydration
- Provide fever-reducing medications under medical guidance
- Keep your child upright to promote easier breathing
FAQs:

3. Is there an RSV vaccine for children?
Currently, RSV vaccines are approved for adults 60 and older and pregnant women in their third trimester. Infants are protected through maternal vaccination.
4. Can RSV be treated at home?
Yes, mild RSV symptoms can be managed with rest, hydration, and over-the-counter medications. Severe cases may require medical attention.
5. How can I protect my baby from RSV?
Follow hygiene practices, avoid crowded places during RSV season, and consult your healthcare provider about maternal RSV vaccination for added protection.
