The following information is intended to help state and local health departments respond to outbreaks associated with recreational water illnesses (RWIs). While some downloadable documents below are cryptosporidiosis-specific, they can also be used as models when creating similar documents for other pathogens. Likewise, though this page was produced by CDC’s Division of Parasitic Diseases, some of the information below can be used or adapted for use in non-parasitic RWI outbreaks. All documents can be downloaded and altered as needed.
