The San Francisco Department of Public Health (SFDPH) coordinates cryptosporidiosis surveillance for the five counties served by the San Francisco Public Utilities Commission. SFDPH is cooperating with the California Emerging Infections Program to gather cryptosporidiosis surveillance data in San Francisco and Alameda counties. In the remaining counties (San Mateo, Santa Clara, and Tuolumne), SFDPH established contact with 21 laboratories to institute an ongoing, active, lab-based surveillance system. Of these, 16 (76%) originally agreed to report cryptosporidiosis data to SFDPH, and two (10%) are reporting to California Emerging Infections Program (CEIP), for an overall participation rate of 86%. Three laboratories (14%) have refused to participate. Two of the laboratories that have declined to participate are commercial reference facilities and one is a commercial lab with many local branches. Non-commercial local laboratories served by the reference labs are participating in the surveillance project and are serving as a proxy measure of reference lab activity. Further surveillance information is obtained from the public health departments in each county. Includes tables, figures.
