What is diphtheria?

Diphtheria is a contagious bacteria that can lead to sore throat, low-grade fever, muscle weakness, loss of appetite, enlarged lymph nodes on your neck, a grayish membrane may form over the bridge of your nose, throat and tonsils may block your airway causing it to be difficult to swallow. It is transmitted by person to person though close contact with the discharge from an infected person's eyes, nose, throat or skin. Diphtheria demands immediate attention- any delay may lead to death. The infected person should be hospitalized, isolated and treated with antibiotics such as penicillin. Diphtheria is also known as Corynebacterium diptheriae.
Diptheria is an upper respiratory tract illness. Symptoms of the disease are low fever, sore throat, swollen neck, and swelling of the tonsils, pharynx, and nasal cavity. The disease is spread through physical contact and breathing the air-borne secretions of the infected. The disease has been largely wiped out through vaccinations.
