Fever and whooping cough: what to know

Whooping cough, also called pertussis, often causes repeated bursts of cough. A sharp intake of breath after a coughing bout may make a whooping sound, although some people do not make that sound. Fever can occur, but a new or rising fever may also point to another infection or a complication. Babies may have pauses in breathing, poor feeding, or unusual tiredness rather than a clear whoop.

Arrange medical advice if pertussis is suspected, because early assessment can guide testing, treatment, and steps to reduce spread. Offer frequent fluids and allow rest. Keep the air free from smoke and avoid close contact with infants, pregnant people, and anyone medically vulnerable until a clinician advises that contact is appropriate. Take prescribed medicines exactly as directed; antibiotics may reduce spread and are most useful when started promptly, but they do not instantly stop the cough. Do not give cough medicines or honey to a young child without checking age-appropriate guidance.

Seek emergency help for struggling or noisy breathing, blue or grey lips, repeated pauses in breathing, inability to drink, severe drowsiness, or a child who cannot recover between coughing bouts. Contact a clinician promptly for fever in a young infant, dehydration, chest pain, vomiting that prevents fluids, or symptoms that are worsening. A clinician can also advise about household contacts and [Antibiotic Treatment](/treatments/medical-management/antibiotic-treatment/).

Ask whether the pattern needs a pertussis test, whether close contacts need preventive treatment, how long to stay away from school or work, and which fever relief is suitable for the person’s age and health.
