Shigella infection spreads through the fecal-oral route, typically via contaminated food, water, or direct person-to-person contact. The bacteria, primarily Shigella sonnei, are present in the feces of an infected person. Inadequate hygiene practices, such as improper handwashing after using the toilet, can facilitate the transmission of the bacteria. Contaminated food and water sources, as well as shared surfaces and objects, can harbor the infectious agent. Additionally, the highly infectious nature of Shigella allows for rapid person-to-person transmission, particularly in crowded or unsanitary conditions. Implementing strict hygiene measures and ensuring the safety of water and food sources are crucial for preventing the spread of Shigella infections.
