How is Shigella typically transmitted?

• A. Airborne route
• B. Vector-borne transmission
• C. Fecal-oral route
• D. Surface contact

Answer: (C)

Shigella is primarily transmitted through the fecal-oral route, which involves the ingestion of contaminated food, water, or direct person-to-person contact with fecal matter. This mode of transmission is significant due to the bacterium’s low infectious dose, meaning that even a small number of bacteria can cause illness. Outbreaks often occur in settings with poor hygiene, such as daycare centers or refugee camps, where close personal contact and inadequate sanitation facilities facilitate the spread of the organism.

Understanding this transmission pathway is crucial in managing and preventing Shigella infections. Measures such as promoting hand hygiene, ensuring safe food and water practices, and educating communities about proper sanitation can effectively reduce the incidence of Shigella-related illness.
