Diphtheria is an infection caused by the bacterium Corynebacterium diphtheriae. Most infections are asymptomatic or have a mild clinical course, but in some outbreaks, the mortality rate approaches 10%. Signs and symptoms may vary from mild to severe, and usually start two to five days after exposure. Symptoms often develop gradually, beginning with a sore throat and fever. In severe cases, a grey or white patch develops in the throat called a pseudomembrane. This tough, leathery membrane slowly blocks the airway. Starting with a barking cough similar to what is observed in croup, the neck may also swell, in part due to the enlargement of the facial lymph nodes. The pseudomembrane can grow to cover a wide area of the throat, leading to strangulation and death. Diphtheria can also involve the skin, eyes, or genitals, and can cause complications, including myocarditis, inflammation of nerves, kidney problems, and bleeding problems due to low levels of platelets.
