Data Sources and Outputs for the Waterborne Disease and Outbreak Surveillance System

This figure shows the data sources and outputs for the Waterborne Disease and Outbreak Surveillance System (WBDOSS). Data sources for WBDOSS include outbreaks reported to CDC through the National Outbreak Reporting System (NORS) by jurisdictional health authorities such as states and territories; aquatic facility-related health events not associated with recreational water, which are reported sporadically by jurisdictional health authorities; single water-associated cases of primary amebic meningoencephalitis (e.g., Naegleria fowleri), chemical/toxin poisoning and wound infections (reported sporadically by some jurisdictional health authorities); and recreational water-associated Vibrio cases reported separately to the Cholera and Other Vibrio Surveillance System.

Following analysis of waterborne disease and outbreaks and dissemination of waterborne disease prevention messages, outputs include periodic reports of waterborne disease outbreaks; biennial waterborne disease and outbreak surveillance summaries for recreational water, drinking water and other uses; and the use of surveillance data by public health researchers and policy makers to understand and reduce waterborne disease and outbreaks.
