Do adults get RSV, and who is at highest risk?

Respiratory syncytial virus (RSV) is often thought of as a childhood illness, but adults can—and do—get RSV. Understanding who’s most at risk, how it presents, and what you can do to protect yourself helps keep you and those around you safer and healthier.

What is RSV?

RSV is a common respiratory virus that usually causes mild, cold-like symptoms. It spreads easily through droplets when an infected person coughs or sneezes, or by touching surfaces contaminated with the virus.

Key points:

• RSV stands for respiratory syncytial virus.
• It circulates seasonally, often peaking in fall and winter.
• Reinfections can occur throughout life—even in adulthood.

Do adults get RSV?

Yes. While RSV is best known for causing severe infections in infants and young children, adults of all ages can contract it. In most healthy adults, RSV causes symptoms similar to a mild cold:

• Runny or stuffy nose
• Sore throat
• Cough
• Mild headache
• Low-grade fever
• Fatigue

Symptoms usually appear 4–6 days after exposure and resolve within one to two weeks.

Why isn’t RSV just a “child’s illness”?

• Reinfection is common. Immunity after an RSV infection wanes quickly.
• Virus variability. Multiple strains circulate each season, allowing reinfection.
• Similar symptoms. In adults, mild cases may be mistaken for the common cold or flu.

Who is at highest risk for severe RSV?

Although most healthy adults experience only mild illness, certain groups face higher risks of complications—including pneumonia and bronchitis—that may require hospitalization.

High-risk groups include:

• Older adults (65 years and older).
  • Age-related changes in immune response
  • Presence of chronic health conditions
• People with chronic heart or lung disease.
  • Congestive heart failure
  • Chronic obstructive pulmonary disease (COPD)
  • Asthma
• Individuals with weakened immune systems.
  • Cancer treatment, organ transplant recipients
  • HIV/AIDS, immunosuppressive medications
• Adults with serious neurological or neuromuscular conditions.
  • Impaired ability to clear secretions
• Pregnant women.
  • Though risk of severe RSV is lower than for flu, caution is advised

Signs of severe illness

Seek medical attention if you experience:

• High fever (over 102°F or 38.9°C)
• Rapid or difficult breathing
• Wheezing
• Chest pain
• Dehydration (dry mouth, little or no urine)
• Confusion or severe lethargy

For non-urgent concerns, you might start with a free, online symptom check, using the doctor approved Ubie Symptom Checker.

How is RSV diagnosed in adults?

Diagnosis often relies on clinical evaluation. In mild cases, testing may not be necessary. However, if your symptoms are severe or you belong to a high-risk group, your healthcare provider may order:

• Nasal or throat swab for RSV antigen or PCR testing
• Chest X-ray (if pneumonia is suspected)
• Blood tests (to check white blood cell counts, oxygen levels)

Treatment and management

There’s no specific antiviral treatment approved for RSV in most healthy adults. Management focuses on relieving symptoms and preventing complications.

Self-care measures:

• Rest and limit physical activity.
• Stay hydrated: water, broth, electrolyte solutions.
• Use saline nasal sprays or rinses for congestion.
• Take over-the-counter pain relievers (acetaminophen or ibuprofen) for fever and aches.
• Use a humidifier to moisten air and ease breathing.

For high-risk adults or severe cases:

• Supplemental oxygen in hospital settings.
• Intravenous fluids if dehydration occurs.
• Mechanical ventilation or noninvasive ventilation (in critical cases).
• Ribavirin (a specific antiviral) may be used rarely in immunocompromised patients.

Preventing RSV in adults

Although you can’t eliminate risk entirely, these steps help reduce your chances of getting RSV or passing it on:

1. Practice good hand hygiene

   • Wash hands with soap and water for ≥20 seconds.
   • Use alcohol-based hand sanitizers when washing isn’t possible.

2. Avoid close contact with sick individuals

   • Keep distance if someone is coughing or sneezing.
   • Don’t share utensils, cups, or towels.

3. Clean and disinfect surfaces

   • Focus on doorknobs, light switches, phones, and countertops.

4. Cover coughs and sneezes

   • Use a tissue or your elbow, not your hands.

5. Stay home when ill

   • Prevent spreading the virus to coworkers, family, and high-risk individuals.

6. Consider vaccination (where available)

   • New RSV vaccines for older adults are becoming available.
   • Speak with your doctor about whether RSV vaccination is right for you.

RSV vs. flu vs. COVID-19

RSV, influenza, and COVID-19 can all cause respiratory symptoms. Here’s a quick comparison:

Feature	RSV	Flu	COVID-19
Onset	Gradual (4–6 days)	Sudden (1–4 days)	Gradual to sudden (2–14 days)
Fever	Low or none	Common, often high	Common, variable
Aches & chills	Mild	Prominent	Prominent
Cough	Common	Common	Common
Severe complications	Mostly in high-risk	High in high-risk	High in high-risk

Accurate diagnosis may require testing since symptoms overlap. If you’re unsure which illness you have, try a free, online symptom check, using the doctor approved Ubie Symptom Checker.

When to see a doctor

Contact your healthcare provider if you:

• Belong to a high-risk group and develop RSV symptoms.
• Have trouble breathing, chest pain, or rapid heart rate.
• Experience persistent high fever or confusion.
• Can’t keep fluids down, leading to dehydration.

Never ignore symptoms that feel serious or life threatening. If you’re in crisis (severe breathing difficulty, chest pain, sudden confusion), call emergency services immediately.

Key takeaways

• Adults of all ages can get RSV; most cases are mild.
• Severe illness is more likely in older adults, those with chronic conditions, and immunocompromised individuals.
• No specific treatment exists for most adults—care is supportive.
• Prevent COVID-19 and flu-like viruses with good hygiene, distancing, and vaccination where appropriate.
• Use the Ubie Symptom Checker for a free, online symptom check, using the doctor approved Ubie Symptom Checker.
• Speak to a doctor about anything that could be life threatening or serious.

Staying informed and taking simple precautions goes a long way in protecting yourself and your community from RSV and other respiratory viruses. If you’re ever in doubt about your symptoms, always reach out to a healthcare professional.
