  1. California STD Surveillance2017 Data Graph Set

  2. The STD surveillance systems operated by state and local STD control programs are the sources of California data in this slide set. Case reports are submitted to local health jurisdictions in the form of laboratory reports and Confidential Morbidity Reports (CMRs). The local health jurisdictions then submit the data to the California Department of Public Health (CDPH), with the majority using the California Reportable Disease Information Exchange (CalREDIE) system. A small number of health jurisdictions report case data from county-generated databases. Rates by county and selected city health jurisdictions were calculated using State of California, Department of Finance, E-6. Population Estimates and Components of Change by County, July 1, 2010–2017,Sacramento, California, December 2017. Rates by age, race/ethnicity, and gender were calculated using State of California, Department of Finance, Report P-3: State and County Population Projections by Race/Ethnicity, Detailed Age, and Gender, 2010-2060, Baseline 2016. Sacramento, California, February 2017. The race and ethnicity information listed and the corresponding census categories are: Native American/Alaska Native (Native American /Alaska Native, non-Hispanic) Asian/Pacific Islander (Asian or Native Hawaiian/Pacific Islander, non-Hispanic) Black (Black or African-American, non-Hispanic) Hispanic/Latino (Hispanic ethnicity, regardless of race designation) White (white, non-Hispanic) Other (Other, non-Hispanic) Multi (2 or more races, non-Hispanic), and Not Specified (no race or ethnicity information was available) Data Sources

  3. The substantial amount of missing race/ethnicity data from the laboratory reports and CMRs limits the interpretation of race/ethnicity data from surveillance data. The majority of case reports originate from laboratories, a group which does not routinely collect data on race/ethnicity. Further, some managed care organizations and other health care service providers do not routinely record race/ethnicity of patients. The observed racial/ethnic disparities may reflect true differences in the infection rates, differential access to health care, and/or reporting practices of different types of providers that serve different populations. The “year” for California data presented in these slides is based on a hierarchy of dates (i.e., the earliest of the following dates: clinic visit, specimen collection, diagnosis, treatment, and lab report/CMR received by the health jurisdiction). In slides on race/ethnicity, where space is limited, the following abbreviations are used: NA/AN = Native American/Alaska Native A/PI = Asian/Pacific Islander Increasing trends in chlamydia cases are difficult to interpret due to the asymptomatic nature of the disease, improved reporting by providers, expansion of screening programs across diverse health care settings, and increased availability of more sensitive diagnostic tests. For prevalence monitoring slides, percent positive in males is generally higher than females, not necessarily because the true prevalence is higher, but most likely because men seen in these venues are typically tested for symptomatic reasons whereas screening programs exist for women. More recent data on major trends can be found in the quarterly updated graph set on the CDPH STD Data page (https://www.cdph.ca.gov/Programs/CID/DCDC/Pages/STD-Data.aspx). Data Limitations/Notes
