Diphtheria is a bacterial disease spread mainly by exhaled water droplets and occasionally through infected skin lesions. It can be fatal if left untreated. Travellers are at risk when mixing closely with the local population in most developing countries. If they are likely to be at risk, travellers should ensure they have had a Diphtheria vaccine within the last 10 years.
