Average annual coccidioidomycosis incidence and incidence rates (IR) by race-ethnicity (N = 2234), Los Angeles County, California, 1995–2011.

<p>Legend. *2004–2011 excludes 2006–2008 because of substantial missing race-ethnicity data during those years and the missing data coincides with substantially less white cases. **Average annual incidence rates per 100,000 people were calculated by dividing the average annual number of cases for 1995–2003 and 2004–2011 (excluding 2006–2008) by the U.S. Census population counts for 2000 and 2010, respectively. Race-ethnicity categories are mutually exclusive. Between 1995–2003 and 2004–2011, all race-ethnicity categories had large increases in average annual incidence and in average annual incidence rate. The average annual number of cases increased from 7.0 to 17.6 for Asians (151%), 10.8 to 34.4 for blacks (219%), 20.6 to 72.6 for Hispanics (252%), and 20.3 to 82.4 for whites (306%). The average annual incidence rate per 100,000 people increased from 1.16 to 4.22 (264%) for blacks, 0.69 to 3.02 (338%) for whites, 0.48 to 1.55 (223%) for Hispanics, and 0.62 to 1.33 (115%) for Asians. Whites and Hispanics had the most number of annual cases on average, but blacks and whites had the highest incidence rates.
