2. Diphtheria is an infection caused by the bacterium Corynebacterium diphtheriae.
Signs and symptoms may vary from mild to severe. They usually start two to five days after exposure.
Symptoms often come on fairly gradually beginning with a sore throat and fever.
In severe cases a grey or white patch develops in the throat. This can block the airway and create a
barking cough as in croup. The neck may swell in part due to large lymph nodes. A form of diphtheria
that involves the skin, eyes, or genitals also exists.

Travelers should be aware of:
•Persistence of disease in many regions of the world to which unvaccinated individuals are susceptible
•Waning immunity from diphtheria vaccine with increasing age
•Individuals with an incomplete primary vaccination history for diphtheria, irrespective of region of
travel
•10 yearly boosters of vaccine should be given for travel to epidemic/endemic areas particularly where
individuals will be mixing with the local population (e.g. health workers, teachers, volunteers).
