What is diphtharia?

Diphtheria is a serious bacterial infection caused by Corynebacterium diphtheriae, which primarily affects the throat and nose. It is characterized by the formation of a thick gray or white coating in the throat, leading to difficulty breathing, swallowing, and potential airway obstruction. Diphtheria spreads through respiratory droplets and can lead to severe complications if untreated, including heart failure and nerve damage. Vaccination has significantly reduced its incidence, making it a preventable disease.
