Update 2:53 p.m. April 27

The mobile coronavirus testing site in Waller County administered 106 tests April 26, according to an April 26 Facebook post from County Judge Trey Duhon.

Duhon said results of the tests will return in two to three days.

"Usually, testing sites see a 10% positive rate," he wrote. "Based on 106 tests, it won’t be unusual if we add 10-11 confirmed cases this week in addition to the average trickle of cases."

Duhon thanked the Waller County departments that worked together to host the mobile testing site.


"The mobile testing site today at the Waller County community center was extremely successful," Duhon wrote. "Everything went very smoothly, and most people that were tested were in and out in five minutes."

The state-run mobile testing site conducted COVID-19 testing for one day only. It had the capacity to perform 120 tests, Duhon said. It was important to administer as many tests as possible so that the mobile site could return to the county sooner, he said in another April 26 Facebook post.

As of 6:56 p.m. April 26, Waller County had a total of 28 confirmed positive cases of the coronavirus. Seventeen cases have recovered, according to the county's website.

Waller County will host a mobile coronavirus testing site April 26 in Prairie View, County Judge Trey Duhon announced on Facebook.

The site will only accept patients who are screened, approved and provided a time slot for a drive-thru test, he added. Residents who show up without going through these steps will not be tested.

Testing is limited, so individuals wanting a test must go through a registration process. Registration begins 9 a.m. April 24. Individuals can register by going online to www.txcovidtest.org or calling 512-883-2400.

The drive-thru testing site will be open 9 a.m.-6 p.m. April 26 at the Waller County Community Center, 21274 FM 1098 Loop, Prairie View.


The testing site’s prescreening process will check for symptoms—such as fever, shortness of breath, sore throat and vomiting—according to a April 23 memo by Dr. Carlos Plasencia, the Department of State Health Services physician who serves as the health authority for Waller County, about the mobile testing site.

However, the site will also test asymptomatic health care workers and asymptomatic individuals who are considered high risk, such as those who have come into close contact with someone who has a confirmed case of the virus or those who another health condition, such as diabetes, heart disease or lung disease, per the memo.

Texas Military Forces will perform the testing at the mobile site, and the tests will be processed at a University of Texas Medical Branch at Galveston laboratory or a UT Southwestern Medical Center laboratory, according to the memo.

According to county data available as of 5:50 p.m. April 23, Waller County has a total of 25 confirmed positive cases. Of those, 17 have recovered. However, the county has not provided the total number of tests conducted.
