* Based on weighted California percentage of respondents.
† Number represents adjusted survey counts, where responses missing either sex, age, or race and ethnicity values was removed from the analysis; respondents missing county information were removed from regional analysis.
§ High-incidence region = ≥10 cases per 100,000 population (Fresno, Kern, Kings, Madera, Merced, Monterey, San Joaquin, San Luis Obispo, Stanislaus, and Tulare counties).
¶ Moderate-incidence region = 2–9 cases per 100,000 population (Alameda, Calaveras, Contra Costa, Imperial, Los Angeles, Mariposa, Orange, Riverside, Santa Barbara, San Bernardino, Santa Cruz, San Diego, Solano, Tuolumne, and Ventura counties).
** Low-incidence region = <2 cases per 100,000 population (all other California counties).
