Deterrence/Prevention
A vaccine for shigellosis is not currently available. Until a vaccine is available, the following measures can help prevent the dissemination of shigellosis:
- Use of safe drinking water
- Chlorination of unreliable water sources
- Strict handwashing
- Refrigeration and proper preparation and cooking of food
- Food handlers must be treated with antibiotics and should not be involved in food preparation as long as stool cultures are positive for Shigella infection.
- At least 48 hours of antibiotic treatment are usually required.
Complications
- Chronic carriers of shigellosis are unusual.
- See Mortality/Morbidity.
Prognosis
- Postinfection carriage is generally less than 3-4 weeks.
- Mild cramps and diarrhea may continue for many days to weeks after treatment of shigellosis.
Patient Education
- Careful handwashing and stool precautions should prevent the dissemination of shigellosis.
