Shigellosis

Shigellosis is a diarrheal infection caused by Shigella bacteria, most commonly S. sonnei and S. flexneri. The organism is spread through the fecal-oral route and humans are the only known host. Food and water contaminated with human fecal matter are common vehicles of transmission. Because the infective dose of Shigella bacteria is very low, this infection is easily transmitted via household or sexual contact. Travelers to developing countries with poor sanitation are also at risk for infection.
