How does diphtheria affect the body and effect the organism?

Diphtheria primarily affects the respiratory system, causing inflammation of the throat and the formation of a thick, gray membrane that can obstruct breathing. The bacteria produce a toxin that can damage heart and nerve tissues, leading to serious complications such as myocarditis and neuropathy. Systemically, the toxin can disrupt cellular function and lead to severe illness or death if left untreated. Vaccination and prompt antibiotic treatment are essential for prevention and management of the disease.
