See the list below:

  • Meticulous hand hygiene is the single most important measure to decrease transmission. In situations where access to clean water or soap is limited, waterless hand sanitizers may be an effective option.

  • For individuals who travel to highly endemic areas, recommend that all fruits and vegetables be washed, peeled, and cooked (see the CDC Web site).

  • In developed countries, person-to-person transmission is the most common source of infection. In developing countries, water contaminated with human waste is the most common source for infection.

  • Encourage prolonged breastfeeding in infants because the incidence of disease is markedly decreased in breastfed babies.

  • The following measures help prevent person-to-person transmission of Shigella species:

    • Education of families and child-care center personnel in handwashing techniques, especially after toilet use

    • Avoidance of food preparation by personnel who change diapers in daycare centers

    • Exclusion of febrile children with diarrhea from daycare centers

    • Proper handling and refrigeration of food, even after cooking

    • Use of universal precautions and isolation of persons with diarrhea in institutions and hospitals

    • Exclusion from daycare centers of symptomatic children, attendees, and staff members with documented Shigella gastroenteritis until diarrhea has ceased and 2 stool culture tests are negative for Shigella

    • If a child in diapers has shigellosis, everyone who changes the child's diapers should be sure the diapers are disposed of properly in a closed-lid garbage can and should wash his or her hands and the child’s hands carefully with soap and warm water immediately after changing the diapers. After use, the diaper changing area should be wiped down with a disinfectant.

    • Exclusion of infected people as food handlers and measures to decrease contamination of food by house flies

    • People with diarrhea due to this waterborne pathogen should not use recreational water venues for 2 weeks after symptoms resolve.

    • Improvements in worker hygiene during vegetable and fruit picking and packing may prevent shigellosis caused by contaminated produce.

    • Appropriate case reporting to health authorities is essential to take effective measures to prevent further transmission.
