Whooping cough in a 6-month-old baby

Suspected whooping cough in a 6-month-old needs prompt medical assessment because babies can develop breathing and feeding problems quickly. Contact the baby's paediatrician or an urgent care service today, even if there is no classic whooping sound. Call UAE emergency services now if the baby is struggling to breathe, has pauses in breathing, turns blue or grey, has a seizure, or is difficult to wake.

Whooping cough, also called pertussis, is a contagious bacterial infection of the airways. It may start with a runny nose, mild cough, or low fever before repeated coughing bouts develop. Babies do not always make a whoop. A 6-month-old with pertussis may instead have pauses in breathing, gag or vomit after coughing, become exhausted, feed poorly, or change colour during a spell. Symptoms and severity vary, so the absence of a whoop does not rule it out.

A clinician may assess the baby's breathing, oxygen level, hydration, feeding, vaccination history, and contact with anyone who has a prolonged cough. Testing may involve a sample from the nose or throat.

Arrange a same-day medical assessment and tell the service that you suspect whooping cough before arriving; this helps staff limit exposure to other patients. Keep the baby away from smoke, fragrances, dust, and people who may be vulnerable to infection. During calm periods, offer the baby's usual milk in smaller, more frequent feeds if tolerated, and watch for fewer wet nappies or repeated vomiting.

Give any prescribed antibiotic exactly as directed. Antibiotics can reduce spread and may lessen illness when started early, but coughing can continue while irritated airways recover. Do not give an over-the-counter cough or cold medicine unless the baby's clinician specifically recommends it. The care team can also advise whether close household contacts need assessment, preventive antibiotics, or vaccination review.

Seek emergency help immediately for pauses in breathing, hard or shallow breathing, ribs pulling in with breaths, blue or grey lips, tongue, face, or skin, a seizure, unusual limpness, or difficulty waking. A baby who cannot feed because of breathlessness, keeps vomiting feeds, or has signs of dehydration also needs urgent assessment.

Contact the clinician again promptly if coughing spells are becoming stronger or more frequent, the baby develops fever or seems much less alert, feeding drops, or wet nappies become noticeably less frequent. Do not wait for a whoop before seeking care.

Ask whether testing or hospital observation is needed, how to monitor breathing and hydration at home, and when the baby is no longer considered contagious. Confirm the antibiotic instructions, what to do after a vomited dose, whether household members need treatment, and how the illness affects the baby's next routine immunisation appointment.
