Diphtheria

Diphtheria is a serious bacterial infection that affects the mucous membranes of the throat and nose. Although it spreads easily from one person to another, diphtheria can be prevented through the use of vaccines.
A type of bacteria called Corynebacterium diphtheria causes diphtheria. The condition is typically spread through person-to-person contact or through contact with objects that have the bacteria on them, such as a cup or used tissue. You may also get diphtheria if you’re around an infected person when they sneeze, cough, or blow their nose.

2. Throat
3. Tongue

Signs of diphtheria often appear within two to five days of the infection occurring. Some people don’t experience any symptoms, while others have mild symptoms that are similar to those of the common cold.
