Wastewater COVID testing shows massive jump in presence of the virus

Jan 5, 2022

HOUSTON — Houston's wastewater testing is showing a massive jump in how much of the COVID-19 virus is present.

There is now 1,694 percent more of the virus in wastewater compared to July of 2020. The positivity rate is now at 27 percent.

Although COVID-19 testing is way up, many cases detected in home health tests aren't reported back to health officials. That’s why testing Houston’s wastewater has become the most accurate way to track the spread of the virus in the city.

The latest results from December 27 show the omicron variant has been detected in nearly all of the water treatment plant in Houston. 

There are 39 water treatment plants spread out across the city. The delta variant is also still present at about a dozen treatment plants.
