Data obtained from those reports is represented below in several ways below to show the number of cases in each city and how those cases have grown over time.

Texas COVID-19 Positivity Rate, Testing, Hospitalized Patients, R-Value

As more testing is done across the state, raw numbers of positive tests will continue to climb. Texas Gov. Greg Abbott said the positivity rate is one of the metrics they rely on to determine the spread of the 2019 novel coronavirus because it will show the daily percentage of those tests that are positive. In early to mid-April, the positivity rate averaged more than 10%. As the rate dropped, Abbott moved forward with his Open Texas plan to allow some businesses in the state to resume operations. Since June 23, the rate has been sustained above 10% -- the threshold Abbott said would be cause for alarm. On Sept. 2, the positivity index dropped back below 10% for the first time in more than two months.

White House Reopening Guidelines Leave Room for Interpretation

For states considering lifting quarantine measures, the official guidelines propose either a downward trajectory of COVID-19 cases within two weeks or a downward trajectory of positive tests as a percent of total tests.

As shown below, when you compare yesterday’s new case count with that of two weeks ago, the number is often lower, simply because the counts fluctuate. The criteria has been criticized by some for being vague, creating the opportunity for any governor to argue the numbers are favorable enough to start reopening.
