/ Patients are tested for COVID-19 at the Community Action Health Center in Falfurrias on Nov. 13, 2020. COVID-19 testing has dropped to its lowest point in Texas since last fall, and health experts say the trend reflects the overall improvement in the course of the pandemic statewide. During the February winter storm that left millions of Texans without access to electricity or water, testing rates dipped below 50,000 tests per day on average for the first time since September. Testing levels rebounded after the winter storm, but the number of tests reported in March is still significantly lower than during December, January and February at the peak of the pandemic in Texas.
