Overview
Diphtheria (Greek διφθερα (diphthera) — “pair of leather scrolls”), is an upper respiratory tract illness characterized by sore throat, low-grade fever, and an adherent membrane (a pseudomembrane) on thetonsils, pharynx, and/or nasal cavity.[1][2] A milder form of diphtheria can be restricted to the skin. It is caused by Corynebacterium diphtheriae, a facultatively anaerobicGram-positive bacterium.[3]
Diphtheria is a highly contagious disease spread by direct physical contact or breathing the aerosolized secretions of infected individuals. Once quite common, diphtheria has largely been eradicated in developed nations through wide-spread vaccination. In the United States for instance, between 1980 and 2004 there have been 57 reported cases of diphtheria (and only five cases since 2000)[4] as the DPT(Diphtheria–Pertussis–Tetanus) vaccine is given to all school children. Boosters of the vaccine are recommended for adults since the benefits of the vaccine decrease with age; they are particularly recommended for those traveling to areas where the disease has not been eradicated.
Historical perspective
Before 1826, diphtheria was known by different names across the world. In 1826, Diphtheria was named in 1826 by French physician Pierre Bretonneau. The name alludes to the leathery, sheath-like membrane that grows on the tonsils, throat, and in the nose.[5][6]
