Shigellosis

Factsheet

Shigellosis is a bacterial infection that affects the intestines. It is one of the more common causes of diarrhea. Most cases are seen in the summer and early fall and occur as single cases or outbreaks.


Disease Reporting

 
Health-care providers and clinical laboratories are required to report cases and suspect cases of shigellosis to local health departments within one working day of identification.

Cases are subject to restriction on school and day-care attendance, food handling, and patient care while in the communicable stage of the disease, or for the duration of any diarrhea and/or vomiting.

In general, restrictions on cases with shigellosis or Shiga-toxigenic Escherichia coli infection shall not be lifted until results of licensed laboratory tests of two consecutive approved fecal specimens collected not less than 24 hours apart show no identifiable pathogens. If sufficient measures have been taken to prevent transmission, or the disease is no longer communicable, worksite, child-care and school restrictions can be removed at the discretion of the local public health authority; school restrictions can be removed by a school nurse or health care provider; and health-care facility restrictions can be removed by the facility's infection control committee.
