How long does Diphtheria generally last?

Diphtheria is an infectious disease caused by the bacterium Corynebacterium diphtheriae, which primarily affects the respiratory system. Once a person is infected, the symptoms typically develop within two to five days of exposure. During this period, the infection manifests with symptoms such as sore throat, fever, and a characteristic thick coating in the throat, which can lead to serious complications if not treated promptly.

The correct time frame of two to five days reflects the average duration for which symptoms are notably present and the bacteria can be contagious. Treatment with appropriate antibiotics, along with diphtheria antitoxin to neutralize the toxin produced by the bacteria, can alleviate symptoms and reduce the duration of illness. Without treatment, the disease can progress and result in more severe health issues, but the acute phase generally lasts within that two to five-day window. Understanding this timeframe is critical for recognizing symptoms early and seeking timely medical intervention.
