Waterborne Disease Outbreak Investigation Toolkit
The Waterborne Disease Outbreak Investigation Toolkit is a guide to assist state and local health departments in conducting waterborne disease outbreak investigations. CDC developed this toolkit to help partners address the unique challenges they face when investigating waterborne disease outbreaks. Because of the numerous ways in which water impacts every person’s daily life, timely detection, response, and control of these outbreaks are crucial to protect public health.
Using experiences of epidemiologists at the state and local levels, this toolkit describes best practices in preparing for, identifying, and responding to a waterborne disease outbreak.
For outbreaks related to recreational water, visit CDC’s Recreational Water Illness Outbreak Response Tools page.
CDC is available to assist local, state, territorial, and tribal health departments—as well other countries’ ministries of health—with investigating and controlling waterborne disease outbreaks.
