How is diphtheria spread?
Diphtheria is spread from person-to-person by coughing or sneezing.
In Australia, it is now more commonly acquired in adults rather than children – as most children have high levels of immunity due to immunisation programs. To prevent the spread of diphtheria, high levels of immunity are required in all age groups – which is why both adults and children are advised to be vaccinated against diphtheria.
In rare cases, the bacteria that cause diphtheria can cause a skin infection (called cutaneous diphtheria), and in these cases, the disease may spread by having contact with pus from the wound.
