What should you know about diphtheria contagious?

The bacteria may pass when an infected person coughs, sneezes, or has close face-to-face contact. Contact with contaminated secretions or objects can also matter. A person may be contagious without dramatic symptoms. Vaccination lowers the chance of illness but does not make every sore throat a sign of diphtheria. Sore Throat has general symptom guidance, while suspected diphtheria requires specific clinical advice.

Call a healthcare service before arriving and explain the possible exposure. Keep distance from others, avoid sharing cups or utensils, cover coughs, wash hands, and use a well-fitting mask if advised. Follow instructions about testing, preventive medicine, and contact tracing. Do not stop prescribed medicine early; Antibiotic Treatment explains why treatment plans should be followed as directed. Check whether household members are up to date with Childhood Immunisation.

Get emergency help for breathing difficulty, inability to swallow saliva, severe weakness, confusion, or quickly increasing neck or throat swelling. Contact a clinician urgently after close contact with a suspected case, particularly if fever, sore throat, hoarseness, or a coating in the throat develops. Keep the person separate while awaiting instructions.

Ask how long to avoid close contact, whether household contacts need testing or preventive medicine, and when it is safe to return to work, school, or childcare. Ask whether your vaccination record changes the advice.
