Respiratory Syncytial Virus (RSV) is a highly contagious virus affecting the respiratory system, commonly causing mild, cold-like symptoms in adults and severe lower respiratory tract infections in infants, young children, and older adults, particularly those with compromised immune systems.

Respiratory Syncytial Virus Infection FAQ


What are the common symptoms of RSV in children?

Common symptoms include runny nose, coughing, sneezing, fever, and wheezing, often resembling a cold but may progress to bronchiolitis or pneumonia.

How is RSV transmitted?

RSV spreads through respiratory droplets from coughing/sneezing, direct contact with contaminated surfaces, or close contact with an infected person.

Who is at high risk for severe RSV infection?

Premature infants, young children with heart or lung disease, and older adults with weakened immune systems are at higher risk.

Is there a vaccine for RSV?

Currently, no widely available vaccine for RSV, though research is ongoing. Prevention focuses on hygiene and avoiding close contact with infected individuals.

How is RSV diagnosed?

Diagnosis typically involves a physical exam, medical history, and may include nasal swab tests to detect the virus.

What is the treatment for RSV?

Treatment is supportive, focusing on symptom relief with fluids, rest, and oxygen if necessary. Antiviral medications are not routinely used.

Can adults get RSV?

Yes, adults can contract RSV, often experiencing mild cold-like symptoms, but may transmit the virus to high-risk individuals.

How long does RSV infection last?

Most cases resolve within 1-2 weeks, but severe infections in high-risk individuals may require hospitalization.

Can RSV be prevented?

Prevention measures include frequent handwashing, avoiding close contact with sick individuals, and disinfecting surfaces.

What complications can arise from RSV?

Potential complications include bronchiolitis, pneumonia, and exacerbation of underlying respiratory conditions like asthma.

Is Palivizumab effective against RSV?

Palivizumab (Synagis) is a monoclonal antibody that helps prevent severe RSV infection in high-risk infants, but does not treat active infections.

When is RSV most common in Malaysia?

RSV outbreaks in Malaysia typically occur during the rainy season, with increased cases from October to March.

Can RSV lead to asthma?

Severe RSV infection in early childhood may be associated with an increased risk of developing asthma later in life.

How to care for a child with RSV at home?

Keep the child hydrated, use a cool-mist humidifier, and monitor for worsening symptoms like difficulty breathing.

When to seek medical attention for RSV symptoms?

Seek immediate care if experiencing difficulty breathing, high fever, or signs of dehydration, especially in high-risk individuals.
