Usage Notes

Diphtheria is a noun that refers to a specific disease, and should not be used as a verb or an adjective. It is often used in medical contexts, and may be pronounced differently in different regions.

Additional Information

Diphtheria is usually transmitted through close contact with an infected person, and can be spread through respiratory droplets or by touching contaminated surfaces. Symptoms typically appear within 2-5 days after exposure and may include sore throat, fever, difficulty swallowing, and a thick, gray membrane on the tonsils. If left untreated, diphtheria can lead to respiratory complications, heart problems, and even death.

Treatment usually involves antibiotics and supportive care, and vaccination is the most effective way to prevent the disease.
