Common in many countries in Asia, the Middle East, eastern Europe, the Caribbean and the South Pacific (see map), while outbreaks have also been reported in other countries.1,4 The disease is more common in countries which do not offer routine vaccination.
The main symptom is a grey/white membrane (coating) in the throat which can lead to difficulty in breathing or swallowing.1,4 It can also cause fever, sore throat, nausea, headache and swollen glands in the neck.1
