Collin County recently added a disclaimer to its COVID-19 dashboard that says the county does not have confidence in the accuracy of the data currently being provided by the Texas Department of State Health Services. County commissioners decided on the disclaimer during a discussion Aug. 17 about the backlog of coronavirus test results submitted by several commercial laboratories last week to DSHS.
As the backlogged results are added to the electronic reporting system, some counties are receiving notification that positive results of the virus that were previously diagnosed but not reported to the local health department at the time the test was completed. As a result, statewide confirmed case counts and some county case counts have recently included some older cases.
"Collin County chose to have the state take over its COVID-19 case investigations and contact tracing and to use DSHS data for its public reporting," DSHS officials said in an emailed statement. "Since that transition in June, DSHS has been providing the most complete data available each day. As with all COVID-19 data, it is subject to change as more information comes in."
With the added backlog of cases, McKinney reported 356 new cases in the last week.
Among the ZIP codes for McKinney, the 75071 and 75070 ZIP codes both had the greatest number of new confirmed cases, with 126, between Aug. 14-20. That brings the total number of cases in those ZIP codes to 597 and 426, respectively.
The ZIP code with the second-highest number of new cases in the past week is ZIP code 75069, which reported 125 cases, bringing its total to 610. ZIP code 75072 reported three new cases. Data shows the 20-29 age group in Collin County has had the highest number of total COVID-19 cases, but the age group is closely followed by those ages 40-49 and ages 30-39, respectively. In addition, the data shows 33 total deaths in McKinney, with a death rate of 2%, according to city data. The total number of deaths since tracking began in March is 98 for Collin County.
Among the key indicators being watched by experts is the number of hospitalizations. Collin County reported 111 COVID-19 patients were hospitalized as of Aug. 20. That number has generally decreased since the beginning of the month. Statewide, the number of patients who have tested positive with COVID-19 and are currently hospitalized is 6,879 as of Aug. 13. That compares with 8,065 patients who were hospitalized and had COVID-19 a week ago.
Experts are watching the state’s positivity rate, which hit a record high in Texas on Aug. 11 with a rate of 24.5%, but has since declined to 16.08% as of Aug. 12. The rate is averaged over the previous seven days and calculates the ratio of positive new cases compared with the number of tests. Gov. Greg Abbott has previously said that a rate of 10% or more is cause for concern.
Here is a look at the rate since early April.
