Shigellosis was first identified by Japanese microbiologist Kiyoshi Shiga in 1897, who isolated the bacterium *Shigella dysenteriae*. His discovery was crucial in understanding bacillary dysentery and developing public health interventions. This breakthrough significantly advanced the field of infectious disease microbiology.
Shigellosis spreads primarily through the fecal-oral route. This occurs when an infected person's stool, even in microscopic amounts, contaminates food, water, or surfaces, which are then ingested by another person. Direct person-to-person contact, contaminated food, and contaminated water are common transmission pathways.
