Diphtheria cases are increasing in some parts of Australia, mostly affecting Aboriginal and Torres Strait Islander people living in regional and remote communities. Recently, there has been a spike in case numbers in South Australia.
Diphtheria is a serious infection that can affect your throat, breathing or skin. It can also spread to other people.
What you can do to protect yourself and your family:
âś” Check your vaccinations are up to date - children, teenagers and Aboriginal adults are eligible for a free diphtheria booster.
✔ Know the symptoms – sore throat, fever, breathing problems or skin sores that won't heal.
âś” See a GP or health service as soon as possible if you are unwell or worried about these symptoms
✔ Simple hygiene can also help stop the spread – wash hands, cover coughs and sores, clean shared surfaces.
Vaccination is safe and can help protect against serious diphtheria illness. Ask your GP, Aboriginal Medical Service or local health service about vaccination today.
