1/ You may have seen headlines in recent days that say Texas has surpassed 1 million coronavirus cases.

But our coronavirus case tracker has the state at 974,230 cases.

Here’s why there’s a discrepancy.

2/ We are using state data, which is also reported to the Centers for Disease Control and Prevention. It does not include "probable cases" in its total case count.

Probable cases come from antigen tests taken by nasal or throat swabs. bit.ly/35f7OXA

3/ Texas tracks antigen tests in a separate dashboard, which you can find here.

More than 35,000 positive antigen tests have been reported.

4/ Other sites or services that say Texas has surpassed 1 million coronavirus cases may be using “probable cases” identified via antigen tests.

5/ It’s important to note: We don’t always know why others have different case counts, largely because their methodologies aren’t always public. bit.ly/35f7OXA

6/6 You can find out more about where our data comes from, along with a timeline for how it has changed dating back to March, at the bottom of this page. apps.texastribune.org/features/2020/…
