I’ll take it where I can get it.
Community spread of coronavirus is on the decline from its recent summertime high, but experts warn that Labor Day gatherings and kids’ return to classrooms could bring a rash of new infections in the coming weeks.
The latest samples of Houston’s wastewater — a highly sensitive method for tracking coronavirus — show diminishing traces of the virus across the region, said Loren Hopkins, the Houston Health Department’s chief environmental science officer. The results indicate a slight drop in person-to-person spread.
“The positivity rates are still alarmingly high, the wastewater rates are still alarmingly high, but it may be trending down,” Hopkins said Wednesday.
The decline could be short-lived.
The holiday weekend and the start of school, which spurred record infections among children, will likely keep the Houston area in “plateau mode” for the foreseeable future, said Bill McKeon, CEO of the Texas Medical Center.
On Tuesday, the Texas Medical Center reported that the rate of transmission across the Houston area was 0.87; the average for the previous week was 0.99. Both figures landing below 1.0 is a good sign; any number above 1.0 means the virus is spreading through the community.
Still, McKeon urged caution. Tuesday’s low daily transmission rate of 0.87 could be artificially deflated due to low testing rates, he said, which commonly occur over holiday weekends.
“We are just coming out of the Labor Day weekend and we typically do not see the impact of holidays for one to two weeks,” McKeon said.

Houston’s coronavirus hospitalizations slowed by 2.3 percent in the past week, but remained only slightly lower than August’s record peak. As of Tuesday, 3,370 people were in area hospitals for COVID-19, down from the record high of 3,500 on Aug. 24, according to the Texas Department of State Health Services.
Ballooning school transmissions are another concern, experts said, especially in districts that do not have mask mandates. Student infections are rapidly rising across the state, with the total number of positive cases among public school students surging by 90 percent just a few weeks into the new school year.
“We need mask mandates to protect our school children from getting infected and bringing it home to Mom and Dad,” said Catherine Troisi, an epidemiologist at Texas Medical Center’s School of Public Health.
The wastewater had documented to surge, and it will be the leading indicator when there is a real decline. I hope people were cautious over the Labor Day weekend, but we’ll know soon enough what if any effect that had. As for mask mandates in the schools, it seems to be working pretty well for HISD. I keep saying, none of this is a mystery, we know what we need to do, we just have to do it.
