Finally, a bit of good COVID news

Naturally, it comes from the wastewater.

Researchers who study sewage to monitor the pandemic are detecting less virus in Houston than they have in months, a positive signal that could indicate a forthcoming drop in new COVID-19 cases, doctors said.

The amount of viral load has declined at 28 out of 38 wastewater treatment plants across the city for the first time in five months, said Dr. Paul Klotman, president and CEO of Baylor College of Medicine. He announced the good news during a Friday video update.

“It’s actually a big drop,” Klotman said. “What that means is, in 7 to 10 days, I think we’re going to see a pretty dramatic drop in the number of new cases.”

Other indicators show signs of improvement. The Houston area’s R(t) value has dipped below 1 for the first time in weeks, meaning community spread is slowing. The test positivity rate for the Texas Medical Center hospital systems dipped from 13.2% last week to 12.7% this week, Klotman said, and the weekly average of COVID-19 hospitalizations is beginning to plateau.

See here, here, and here for the background. As we know, people shed virus in feces and urine, so tracking virus levels in wastewater is a pretty good tool for determining what the true status is and where hotspots are forming. If this is the start of a trend, we’ll see infection and hospitalization levels – not to mention deaths – start to decline rapidly in the next few weeks. Keep wearing your masks and avoiding indoor gatherings, as that’s been our best defense so far, and get that vaccine when you can.
