How does diphtheria enter the body?

1. Inhalation:

- The most common route of entry is through inhalation of respiratory droplets produced by an infected person when they cough, sneeze, or talk.

- These droplets can contain the diphtheria bacteria (Corynebacterium diphtheriae).

2. Direct Contact:

- Diphtheria can be transmitted through direct contact with an infected person's sores or lesions, particularly if there is skin-to-skin contact or contact with contaminated clothing, bedding, or other shared items.

3. Contact with contaminated objects:

- Less commonly, diphtheria can be spread through contact with contaminated objects or surfaces, especially those recently exposed to respiratory droplets from an infected person. Touching contaminated objects and then touching the nose or mouth can introduce the bacteria into the body.

It is important to note that diphtheria is spread primarily through close contact with an infected person or their respiratory secretions. Proper hygiene practices, such as handwashing and covering the mouth and nose when coughing or sneezing, can help prevent the spread of the infection.
