Fig. 1. Monthly Texas coronavirus disease 2019 incidence, hospitalizations, and deaths from March to July 2020. This graph depicts the incidence, average hospitalization days, and mortality rates for Texas from March to July 2020. Monthly cases, mortality, and average hospitalization days increased from month to month, with the highest increases seen from June to July. Although the risk of being infected with coronavirus disease 2019 increased from May to July, the mortality rate significantly decreased in May and June and was insignificant in April and July. Case fatality ratios showed a similar trend, with the highest death case ratio in April and a subsequent decrease from May to July. *Statistical significance of relative risk.
Fig. 2. Total cases, daily hospitalizations, fatalities, and case fatality ratios at study time points. The total number of positive cases was 325,030 and deaths was 3958 on July 19, which increased to 430,485 cases and 6387 deaths on August 1. Cases increased over time, whereas daily hospitalizations decreased, possibly because of increased recoveries or discharges home and fatalities. Fatalities increased at the end of July, corresponding to an increase in death case ratio over time. The chance of acquiring COVID-19 from each study point to the next increased significantly, whereas the chances of being hospitalized with COVID-19 decreased steadily throughout time. The probability of dying from COVID-19 was only significant from July 22 to July 27. *Statistical significance of odds ratio. COVID-19, coronavirus disease 2019.
Fig. 3. Impact of sex, age, and race/ethnicity on COVID-19 case fatality ratios at study time points. (A) Case fatality ratios between males and females. Males had higher case fatality ratios at all study points compared with females. Males had a case fatality ratio of 3.02 on July 19, 2020, which increased to 19.38 on August 1, 2020. (B) Case fatality ratios between individuals younger and older than 65 years. Older adults
had the highest case fatality ratio compared with individuals younger than 65 years old and among other demographics. (C) Case fatality ratios among the different races and ethnicities. Of the known races, Whites, Asians, and Hispanics had the highest case fatality ratios. Although most of the races had an increase in case fatality ratios over time, Whites and Blacks experienced a decrease in death case ratio by the end of July 2020. COVID-19, coronavirus disease 2019.
