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.
