RSV in Babies: Recognizing Symptoms and When to See a Doctor Immediately

RSV — Important for All Parents to Know 🏥

What is RSV?

Respiratory Syncytial Virus — a respiratory virus that infects almost all children by their 2nd birthday. For most it's harmless (like a cold), but for some it can be serious.

Risk Groups

• Premature babies (born before week 37)
• Babies under 6 months old
• Children with heart defects or lung disease
• Immunocompromised children

Symptoms (mild → severe)

Mild (like a cold): Runny nose, cough, slight fever, loss of appetite

Serious (SEE A DOCTOR!):

• Rapid, labored breathing (> 60 breaths/min.)
• Retractions — skin between the ribs pulls in when breathing
• Flaring nostrils — nostrils widen with each breath
• Refusing to feed — baby can't breathe and drink at the same time
• Bluish lips or fingernails
• Apnea — brief pauses in breathing (especially in premature babies)

GO TO THE HOSPITAL IMMEDIATELY if

• Baby under 3 months with respiratory symptoms
• Difficulty breathing (retractions, flaring nostrils, blue lips)
• Baby hasn't drunk anything for 8+ hours
• Baby seems lethargic, barely responsive

Prevention

• Hand washing — most important measure
• Keep sick visitors away
• RSV immunization (Nirsevimab) — recommended for all newborns since 2023
