Cutaneous diphtheria infection is a bacterial infection caused by Corynebacterium diphtheriae that affects the skin. Unlike respiratory diphtheria, which affects the throat and respiratory system, cutaneous diphtheria primarily involves the epidermis and dermis layers of the skin.

Signs and Symptoms[edit | edit source]

The symptoms of cutaneous diphtheria include:

These symptoms typically appear on exposed areas of the body such as the hands, legs, and feet.

Transmission[edit | edit source]

Cutaneous diphtheria is transmitted through direct contact with infected wounds or lesions. It can also spread via contact with contaminated objects or surfaces. The bacteria can enter the skin through cuts, abrasions, or other breaks in the skin.

Diagnosis[edit | edit source]

Diagnosis of cutaneous diphtheria is confirmed through bacterial culture and polymerase chain reaction (PCR) testing of samples taken from the infected skin lesions. Clinical diagnosis is often supported by the characteristic appearance of the ulcers and the presence of a pseudomembrane.

Treatment[edit | edit source]

Treatment involves the administration of antibiotics such as penicillin or erythromycin. In addition, diphtheria antitoxin may be administered to neutralize the effects of the toxin produced by the bacteria. Proper wound care and hygiene are also essential to prevent secondary infections.

Prevention[edit | edit source]

Epidemiology[edit | edit source]
