  • Shigellosis Information for Providers

    For general information, see our shigellosis page.

    Shigellosis is an acute enteric infection.

    Shigellosis causes bacterial diarrhea. It transmits easily from person to person and frequently arises during travel.

    Consider shigellosis in the differential diagnosis of acute diarrhea, especially in people who:

    • Recently travelled outside the United States.
    • Are younger than 5 years.
    • Have oral-anal sexual contact.
    • Live homeless.
    • Live with HIV or other immune-compromising conditions.

    Test people with shigellosis symptoms with stool culture or CIDT.

    • If culture-independent diagnostic test (CIDT) is positive for shigellosis, confirm with stool culture.
    • If you plan to treat with an antibiotic, perform antimicrobial susceptibility testing (CIDT is not sufficient).

    Shigellosis can be a mild, self-limited illness. When treatment is indicated (for people at risk for severe disease or with moderate to severe symptoms), select an antimicrobial agent based on the susceptibility profile of the individual isolate.

    Shigellosis cases are increasing.

    Nationally, providers are reporting increased extensively drug-resistant (XDR) shigellosis.

    Locally, providers are reporting increased drug-susceptible shigellosis, especially among people living homeless.

    Report suspected or confirmed cases within 24 hours.

    Call (253) 649-1413 or use the Notifiable Conditions Fax Form. For more information, see our page.
