aIncidence rates (IR) are calculated per 100,000 population. Estimated population used for 2006-2008 and projected used for 2009-2017. Population data are projected population from Texas Demographic Center’s Texas Populations Projections Program; 2021, 2020 and 2019 population projections were updated March 2022, and 2018 and earlier population projections were from the prior version.
bFor 2018-2021, per the Emerging and Acute Infectious Disease Unit Data Suppression Policy, case counts are not published when underlying populations are less than 2,000, when n <10 for populations 2,000 to 20,000, or when n<5 for populations 20,000 to 400,000. Rates are not provided when underlying populations are less than 2,000 or the Relative Standard Error exceeds 25% (n<16).
