What is Respiratory Syncytial Virus (RSV)?
Respiratory Syncytial Virus (RSV) is a common respiratory virus that typically causes mild, cold-like symptoms. However, it can become serious, especially for infants, young children, people with weakened immune systems, and adults aged 60 and older.
Each year, millions contract RSV in the United States, and thousands require hospitalization, particularly during the fall and winter seasons.
How RSV Spreads in the USA
RSV spreads through droplets from coughing or sneezing and can live on surfaces like doorknobs and toys for several hours. It’s particularly common in schools, daycare centers, and healthcare settings.
Who is at Risk?
Those most at risk for severe RSV include:
- Infants under 6 months of age
- People aged 60 and older
- Individuals with chronic heart or lung conditions
- Immunocompromised individuals
- People living in long-term care facilities
- Pregnant people
Respiratory Syncytial Virus Symptoms
In Infants and Young Children
- Runny nose
- Decreased appetite
- Coughing and sneezing
- Fever
- Wheezing
- Irritability
In Adults and Older Populations
- Mild congestion
- Sore throat
- Cough that may linger
- Fatigue
- Breathing difficulty (in severe cases)
Seek medical attention if someone experiences:
- Trouble breathing
- Blue-tinted lips or fingertips
- Dehydration or refusal to eat
- High, persistent fever
How RSV is Diagnosed
Doctors diagnose RSV using:
- Nasal swab antigen tests
- PCR testing, which is more sensitive
- Physical exams and review of symptoms
Early diagnosis is critical to preventing complications, especially for high-risk individuals.
6. Treatments for Respiratory Syncytial Virus
At-Home Treatments
For mild cases:
- Hydration is key
- Use saline drops for nasal congestion
- Apply cool-mist humidifiers
- Over-the-counter medications for fever (if approved by a healthcare provider)
Hospital-Based Care
People with more severe cases may need:
- Intravenous (IV) fluids
- Oxygen support
- Mechanical ventilation (in rare cases)
New and Emerging Treatments
Monoclonal antibody treatments like nirsevimab are now recommended for infants and young children at high risk. Antiviral drugs are currently under clinical trials.
Vaccination for Respiratory Syncytial Virus
2023 marked a breakthrough for RSV prevention with the approval of the first RSV vaccines for older populations and pregnant people.
Approved Vaccines in the USA (2025)
- Arexvy (GSK) – For people aged 60+
- Abrysvo (Pfizer) – Approved for people aged 60+ and pregnant people in their third trimester
Effectiveness
Clinical trials show that vaccination reduces the risk of severe illness and hospitalization by over 80%.
Safety
Most side effects are mild:
- Injection site pain
- Low-grade fever
- Fatigue
Vaccination is recommended before the fall RSV season for optimal protection.
RSV and Infants: Key Concerns
Infants under 6 months face the highest hospitalization rates. Their lungs are still developing, and RSV can quickly lead to bronchiolitis or pneumonia.
Protection tips:
- Keep infants away from crowded places during peak seasons
- Ensure caregivers wash hands frequently
- Discuss monoclonal antibody protection with pediatricians
RSV in Adults Aged 60+
Older adults, especially those with chronic conditions, are at greater risk for serious RSV complications.
Preventive steps:
- Get vaccinated before the RSV season
- Avoid contact with sick individuals
- Seek immediate care for respiratory symptoms
Preventing RSV at Home and in the Community
Best Practices
- Wash hands with soap for at least 20 seconds
- Disinfect toys, counters, and mobile devices
- Avoid kissing babies on the face during RSV season
- Wear masks in healthcare facilities or crowded spaces
Long-Term Impact of RSV
For some, RSV can lead to chronic respiratory problems, such as:
- Recurrent wheezing
- Asthma
- Reduced lung function in early childhood
Research is ongoing to explore long-term lung health after severe RSV infections.
RSV vs. Flu vs. COVID-19
| Symptom | RSV | Flu | COVID-19 |
|---|---|---|---|
| Fever | Sometimes | Often high | Often |
| Wheezing | Common | Rare | Rare |
| Cough | Persistent | Dry | Persistent |
| Fatigue | Mild | Severe | Moderate to severe |
| Prevention | Vaccine & hygiene | Vaccine | Vaccine & hygiene |
Public Health Efforts Against RSV in the USA
The Centers for Disease Control and Prevention (CDC) has issued updated guidelines and launched awareness campaigns to reduce RSV cases nationwide.
Notable efforts include:
- Promoting RSV vaccine coverage
- Educating pediatricians and OB/GYNs
- Distributing educational materials to schools and community centers
Future Research on RSV
Exciting developments underway:
- Nasal spray vaccines in early trials
- Combination vaccines targeting RSV, COVID-19, and the flu
- Improved rapid diagnostics for home and clinic use

FAQs About RSV
1. Can RSV be prevented?
Yes. Vaccines and good hygiene can significantly lower your risk.
2. Is there a vaccine for RSV?
Yes. As of 2025, vaccines are available for people aged 60+ and pregnant people.
3. How do I know if it’s RSV or just a cold?
RSV causes wheezing and rapid breathing, especially in infants. A swab test can confirm it.
4. Can adults get RSV?
Yes, especially older adults and people with chronic illnesses.
5. What is the best treatment for RSV?
Mild cases resolve with home care. Severe cases may require oxygen and fluids.
6. Can RSV lead to long-term problems?
Yes, particularly in children. It may contribute to asthma and other respiratory conditions.
Conclusion
Respiratory Syncytial Virus (RSV) remains a serious seasonal virus in the USA. However, with early detection, updated vaccinations, and public health awareness, the outlook for 2025 is brighter than ever.
