If your child has a bad cough or flu-like symptoms during the rainy season, it could be Respiratory Syncytial Virus (RSV) — a common but highly contagious infection that affects the lungs and airways, especially in babies.
Dr. Jovitra says: “RSV spreads very easily — almost every child will be infected by age two. Most recover well, but some, especially infants, can become quite sick.”
🌧️ When and How It Spreads
In Malaysia, RSV can appear all year but peaks from September to December, during the monsoon season. The virus spreads through coughs, sneezes, or contact with contaminated hands or surfaces — often passed from adults or older siblings who have only mild cold symptoms.
🤧 Common Symptoms
Toddlers (2–3 years)
Infants (below 1 year)
Fever, cough, runny nose
Reduced appetite, tiredness
Fever, cough, nasal congestion
Poor feeding or vomiting after coughing
Fast breathing or wheezing
“If your baby is breathing fast, feeding poorly, or looks unusually tired — bring them in right away,” advises Dr. Jovitra.
🏥 Treatment
There’s no specific cure for RSV, but most children get better with:
Plenty of fluids and rest
Fever medicine (if advised by the doctor)
Nasal sprays for congestion
Avoiding crowded areas
Because RSV is viral, antibiotics won’t help unless there’s another bacterial infection.
💉 Prevention Matters
Maternal Vaccination (Abrysvo®) Expectant mothers between 32–36 weeks can receive this vaccine. It helps pass protective antibodies to the baby before birth — safeguarding newborns for the first six months.
“Maternal vaccination is a safe, effective way to protect your baby early,” notes Dr. Jovitra.
Breastfeeding Breast milk naturally strengthens babies’ immune systems and reduces the severity of RSV infections.
Nirsevimab (Beyfortus®) This single-dose antibody injection provides up to five months of protection and can cut RSV-related hospitalisations by more than 60%.
Awareness is the Best Protection
RSV is common among children, but with awareness and timely care, most recover without complications. As Dr. Jovitra reminds, “Don’t panic if your child catches RSV — most recover well. What’s important is recognising the symptoms early and knowing when to seek medical care.” Simple habits like washing hands often, keeping sick family members apart, and avoiding crowded areas during flu season can go a long way in keeping your little one safe.
