Checking in again on the wastewater

COVID levels keep creeping up.

After the U.S. death toll from COVID-19 hit 1 million deaths on Monday, new data shows numbers on the rise again.

The latest Houston Health Department wastewater results from May 9 show levels are now higher than they were in July of 2020.

The viral load on May 9 was 127 percent higher in comparison to July 6, 2020.

The July 2020 readings serve as a baseline for wastewater testing, since that was during the summer surge of cases.

The positivity rate in Houston is also now at 8 percent. At the end of March, Houston’s wastewater positivity rate was 2 percent.

Since the results are delayed, levels are likely higher now.

Houston Methodist is also reporting a rise in cases over the last two weeks.

“We have also seen our first cases of BA.4 and BA.5, which we will continue to monitor, since literature suggests these variants escape immunity from previous Omicron infection,” [Dr. Wesley Long of Houston Methodist] tweeted. “Vaccines are still our best defense against COVID-19 along with masking and distancing.”

Long also says while the wastewater levels are nearly 30 percent higher than the July 2020 surge, that the public shouldn’t be fearful, but shouldn’t ignore the trend either.

“The bottom line is, the amount of virus in the community is going up,” Long said. “That’s one thing we know for sure. I wouldn’t be worried, but I would be paying attention.”

There was a story in the Sunday print edition of the Chron about the Houston wastewater tracking, with a byline from the NY Times, but I could not find it online. Note that this KHOU story reports on the May 9 virus level in two different ways, saying that the viral load is “127 percent higher” and also that it is “nearly 30 percent higher”. The latter is correct – the Houston COVID dashboard says that the COVID load is “127% in comparison to the July 2020 level”, which is to say up 27%. Pay attention in those math classes, people.

At this point, until there is a new type of vaccine, we have what we’re going to get. I heard on the CityCast Houston podcast that the vax level in Harris County is about 67%, which is better than it used to be but still too low to really slow things down. What we can do is whatever we can to get the unvaxxed people in our lives to get the shots, and we can get boosted – one if we’re under 50, two if we’re over. Get your kids boosted, which also very much means getting them vaxxed in the first place – only about 30% of kids in this range have had two shots, which is just madness to me. Wear your masks when in indoor public places again, and avoid needless indoor public gatherings. You have to take care of yourself now, so do it. Until it gets worse – and I still hope it won’t – this is the best you can do.

UPDATE: The May 16 numbers are now on the dashboard, and they show that we are at 170% of the July 6, 2020 level. Not great!
