IR= incidence rate per 100,000 population. * 2022 data provisional and subject to change.
aIncidence rates (IR) are calculated per 100,000 population. Population data are projected population from Texas Demographic Center’s Texas Populations Projections Program; 2020 and 2019 population projections were updated March 2022, and 2018 & earlier population projections were from the prior version.

aIncidence rates (IR) are calculated per 100,000 population. Incidence rates are based on projected census data obtained from the DSHS Center for Health Statistics. Population data are projected population from Texas Demographic Center's Texas Population Projections Program, updated March 2022. 
bAge is calculated from date of birth to date of patient symptom onset. Other event dates are used when the symptom onset date is unknown.
