Respiratory Syncytial Virus (RSV): Overview
Respiratory syncytial virus (RSV) is a highly contagious seasonal lung infection affecting both children and adults. Most cases are mild, resembling a cold, but severe infections can lead to pneumonia and bronchiolitis. Prevent RSV spread with good hygiene practices. Let's delve deeper into RSV!
What is Respiratory Syncytial Virus (RSV)?
Respiratory Syncytial Virus (RSV) is a respiratory virus causing infections in the lungs and respiratory tract. Children often contract RSV by age two, making it common. Adults are also susceptible.
Most healthy children and adults with RSV experience mild cold-like symptoms, clearing within a week. However, premature newborns, infants under six months, adults over 65, and those with weakened immune systems or chronic conditions are at higher risk for severe RSV complications, including pneumonia and bronchiolitis.
Is RSV Contagious?
Yes, RSV spreads easily, particularly in the first few weeks of symptoms. Some individuals, especially infants and those with weakened immune systems, remain contagious up to four weeks after symptoms begin.
How Does RSV Spread?
RSV spreads through close contact with infected individuals. Coughing or sneezing releases virus particles into the air, infecting others through eyes, nose, or mouth contact. Touching contaminated surfaces and then the face can also transmit RSV.
What are the Symptoms of RSV?
Symptoms typically appear two to eight days after infection. Common RSV symptoms include:

Symptoms of RSV in Babies
Babies under six months may show atypical symptoms like:
- Decreased appetite
- Irritability
- Changes in breathing
- Reduced activity interest
Severe cases may require hospitalization for monitoring, especially with underlying conditions.
Symptoms of RSV in Adults and Children
Older children and adults often have mild symptoms resembling a common cold:
- Congestion
- Runny nose
- Sore throat
- Mild headache
- Fever
- Cough
- Fatigue
Seek emergency care if breathing problems occur or if symptoms persist in high-risk groups.
What Causes RSV?
RSV infects the respiratory tract through the nose and throat, damaging cells in the lower respiratory tract and causing symptoms.
Can RSV Cause Severe Illness?
RSV can lead to serious conditions, including:
- Bronchiolitis
- Pneumonia
- Heart failure exacerbation
- Worsening of asthma or COPD

Children often contract RSV through contact with infected peers. Crowded places increase exposure risk.
Is There a Cure for RSV?
Currently, no specific treatment exists for RSV. Research continues into prevention and management strategies.
How is RSV Treated?
Mild cases require home care, including:
- Hydration
- Nasal mucus management
- Over-the-counter medications for fever and pain (consult a healthcare provider, especially for children)
- Rest and avoidance of smoke or vaping
Severe cases may need hospitalization for oxygen therapy, IV fluids, mucus removal, and antiviral medications.
Conclusion
RSV can be concerning, especially for parents of young children. Prompt medical attention is crucial for infants showing symptoms, particularly those under six months old.
