Overview
All individuals are at risk of developing shigellosis. Individuals at high risk of developing shigellosis are young children between the age of 2 to 5, individuals who engage in anal sexual intercourse, HIV-positive individuals, and travelers to developing countries.
Shigellosis Risk Factors
Young Children
- The majority of shigellosis cases are reported in childcare/school settings or among families with small children.[1]
- Children between the age of 2 to 5 are most susceptible to shigellosis infection and to death associated with the infection.
Anal Sexual Intercourse
- Individuals who engage in anal sexual intercourse are at risk of developing shigellosis.[1]
- Shigella is transmitted via the fecal-oral route. Individuals who engage with anal sexual intercourse may be exposed to fecal residue.[1]
HIV-positive Individuals
- HIV-positive patients may develop severe and prolonged forms of shigellosis.[1]
Travelers
- Individuals who travel to developing countries are at risk of shigellosis following ingestion of contaminated food and water.[1]
