Diphtheria is an infection of the upper respiratory tract and on occasion the skin. Onset is acute and is spread by close contact with other infected individuals. The incubation period between 2-5 days. Untreated subjects become infectious for up to 4 weeks. On milder infections carriers maybe asymptomatic.
Diphtheria can cause nose and throat infections: a tough ‘leathery’ grey/yellow membrane develops, that affects the soft palate, tonsils and throat. Lymph glands become swollen, prominent and tender, producing a ‘bull neck’.
*Vaccines work best if given time to become active. This vaccine can be given up to the day before travel and will provide some cover.
**Children who have have already been immunised with the NHS childhood vaccination program.
