Welcome to the State of California 

CalPHIN Projects

WebCMR and ELR

In 2005, the Department began implementation of the Web Confidential Morbidity Report (WebCMR) and Electronic Laboratory Reporting (ELR) projects. When completed, these projects will provide the State of California with a secure, web-based system for use by health care providers, laboratories, local health departments, and CDPH for the reporting, surveillance, and case management of communicable diseases. WebCMR covers the clinical aspect of reportable diseases whereas ELR covers laboratory results, but both will be part of a single, integrated system of tracking communicable disease.


Initiated in 2005, the CalPHIN Laboratory Information Management System (LIMS) project will implement a common data structure and user interface across all six CDPH laboratories in order to centralize tracking of patient records and laboratory specimens. In addition, the Laboratory Data Interchange (LDI) project will facilitate exchange of laboratory data between clinical and local public health laboratories, CDPH laboratories, and the CDC or other federal partners. In conjunction with these activities, CDPH is one of seven state laboratories participating in the CDC-sponsored Public Health Laboratory Interoperability Project (PHLIP), which promotes the use of PHIN messaging standards.


The California Health Alert Network (CAHAN) is the State of California’s web-based information and communications system available on a 24/7/365 basis for distribution of health alerts, dissemination of prevention guidelines, coordination of disease investigation efforts, preparedness planning, and other initiatives that strengthen state and local preparedness. CAHAN is managed by the Emergency Preparedness Office.
