This page is for public health disease reporters, including but not limited to: laboratories, health care providers, staff in congregate settings, and public health staff who need to report a case and/or outbreak of illness to the department.
Reporting individual cases
Lab reporting requirements
Labs must report diseases and conditions on the reportable communicable diseases and conditions list. The preferred method is via electronic laboratory reporting (ELR). For information on reporting via ELR, contact cdphe_elr@state.co.us. If you are a lab not currently onboarded to ELR you are encouraged to use the Reportal for case reporting.
Lab submission requirements
Specimen submission is in addition to laboratory reporting of required results. Isolate submission to the lab is not reporting and does not satisfy reporting requirements. Here are submission requirements for isolates or clinical material to the CDPHE Laboratory.
- Specimen submission requirements for clinical microbiology laboratories
- Colorado lab guidance for selected reportable antimicrobial resistant organisms

Reporting outbreaks
Outbreaks are instances of more illness in a given timeframe, location, or group of people than what is usually expected. All outbreaks are reportable to public health, regardless of the setting where the outbreak is occurring or the pathogen causing the outbreak.
Providers and other disease reporters
Providers and other disease reporters (including coroners, as well as staff working at schools, licensed child care centers, and higher education institutions) should report known or suspected outbreaks immediately by telephone (within four hours of detection) to either the local public health agency or to CDPHE at 303-692-2700 (after hours 303-370-9395). It is especially important to report outbreaks occurring in congregate settings such as health care facilities, group living homes, child care centers, correctional settings (e.g., jails, prisons), schools, and workplaces.
