What should you know about bact ria bordetella pertussis?

The bacteria attach to the lining of the airways and release substances that irritate them. Early illness may resemble a cold, with a runny nose and mild cough. The cough can then become forceful and occur in repeated bursts; a person may gasp after a bout, and vomiting can follow. Infants may have pauses in breathing rather than a loud cough. Symptoms can continue after the infection itself starts settling.

Arrange a clinical assessment if the cough is worsening, prolonged, or occurring in an infant. Testing may help guide treatment. Antibiotic Treatment can reduce spread when started at an appropriate stage, although it may not immediately stop the cough. Keep the person away from vulnerable contacts as advised, cover coughs, wash hands, and improve airflow indoors. Childhood Immunisation helps prevent pertussis and its complications; ask whether routine doses are up to date.

Seek urgent care for breathing difficulty, blue or grey lips, repeated pauses in breathing, inability to drink, marked drowsiness, or coughing that causes choking. An infant with a suspected exposure needs prompt medical advice even if the symptoms seem mild. A Cough with fever or rapidly worsening breathing should also be assessed without delay.

Ask whether testing is needed, when the person can return to school or work, whether close contacts need advice, and which warning signs require emergency help.
