National Shigella Surveillance System
The National Shigella Surveillance System is based on data collected by state and territorial public health laboratories. Shigella isolates are submitted to the state or territorial public health laboratory by clinical diagnostic laboratories. The public health laboratory confirms the isolates as Shigella and performs subtyping.
State and territorial public health laboratories send reports electronically to CDC through a variety of mechanisms. Initially, all surveillance data were transmitted through the Public Health Laboratory Information System (PHLIS), but other methods of data transmission have been implemented over time; currently data are collected into the Laboratory-based Enteric Disease Surveillance (LEDS) system, which has replaced PHLIS. The Division of Foodborne, Waterborne, and Environmental Diseases (DFWED) in the National Center for Emerging and Zoonotic Infectious Diseases maintains the national Shigella surveillance data in LEDS. The annual summaries of these data are the only regularly published national source of serotype information for Shigella.
