Quick read
Key points
- 1
Whooping cough (pertussis) is a highly contagious bacterial infection causing severe coughing fits, sometimes followed by a distinctive "whoop" sound as the child gasps for breath afterward. It can affect anyone but is most dangerous for young babies, particularly those too young to be fully vaccinated, who are at higher risk of serious complications.

What is Whooping Cough in Babies and Children?
Whooping cough (pertussis) is a highly contagious bacterial infection causing severe coughing fits, sometimes followed by a distinctive "whoop" sound as the child gasps for breath afterward. It can affect anyone but is most dangerous for young babies, particularly those too young to be fully vaccinated, who are at higher risk of serious complications.
Vaccination — including during pregnancy, which passes protective antibodies to the baby before birth — is the most effective way to protect babies during their most vulnerable early months.
02 · Understand
Clinical context
Vaccination in pregnancy protects newborns directly
The whooping cough vaccine given during pregnancy passes protective antibodies to the baby before birth, offering protection during the vulnerable early weeks before the baby's own vaccinations begin.

When to Contact a Doctor (Non-Emergency)
- 1You suspect whooping cough based on the coughing pattern
- 2Your baby or child has been exposed to a confirmed case and isn't fully vaccinated
- 3Coughing fits are frequent and exhausting, even without emergency signs
- 4You have questions about vaccination timing for your baby or during pregnancy

Practical steps
Vaccination Is the Best Protection Available
Whooping cough vaccination — both the routine childhood schedule and vaccination during pregnancy — is highly effective at preventing serious illness in babies and young children.
- 1Complete the full course of any prescribed antibiotics.This helps reduce the infectious period and can lessen the severity of illness if started early.
- 2Offer smaller, more frequent feeds.Coughing fits can make feeding difficult, so smaller amounts more often may help.
- 3Keep your child upright during coughing fits.This can help them recover their breath more easily.
- 4Keep the environment calm and free from irritants.Smoke and strong fumes can trigger further coughing fits.
- 5Keep your child away from young babies and pregnant people until advised it's safe.This reduces the risk of passing the infection to those most vulnerable to serious complications.

BarnMD Bottom Line
Whooping cough is preventable through vaccination, including during pregnancy, which protects babies during their most vulnerable early weeks.
Pauses in breathing or a blue tinge during coughing fits in a baby always need emergency assessment.
