In 2020, a group of researchers began testing Houston's wastewater to collect data to help identify trends at the community level. Now, the team's work has been rounded up to use as an online resource.

The Houston Health Department and Rice University launched the dashboard on September 22. The information comes from samples collected from the city's 39 wastewater treatment plants and many HISD schools.

"This new dashboard is another tool Houstonians can use to gauge the situation and make informed decisions to protect their families," says Dr. Loren Hopkins, chief environmental science officer for the health department and professor in the practice of statistics at Rice University, in a news release. "A high level of virus in your neighborhood's wastewater means virus is spreading locally and you should be even more stringent about masking up when visiting public places."

The health department, Houston Water, Rice University, and Baylor College of Medicine originally collaborated on the wastewater testing. Baylor microbiologist Dr. Anthony Maresso, director of BCM TAILOR Labs, led a part of the research.

"This is not Houston's first infectious disease crisis," Maresso says in an earlier news release. "Wastewater sampling was pioneered by Joseph Melnick, the first chair of Baylor's Department of Molecular Virology and Microbiology, to get ahead of polio outbreaks in Houston in the 1960s. This work essentially ushered in the field of environmental virology, and it began here at Baylor. TAILOR Labs is just continuing that tradition by providing advanced science measures to support local public health intervention."

It's an affordable way to track the virus, says experts. People with COVID-19 shed viral particles in their feces, according to the release, and by testing the wastewater, the health department can measure important infection rate changes.

The dashboard, which is accessible online now, is color-coded by the level of viral load in wastewater samples, as well as labeled with any recent trend changes. Houstonians can find the interactive COVID-19 wastewater monitoring dashboard, vaccination sites, testing sites, and more information at houstonemergency.org/covid19.

Here's when Houston can expect the Johnson & Johnson COVID-19 vaccine

coming soon

Texas can expect to receive the first 200,000 doses of the coveted Johnson & Johnson COVID-19 vaccine this week. The company announced that it has started the rollout process on March 1 — after the FDA approved its Emergency Use Authorization.

The Center for Disease Control gave the developer, Janssen Pharmaceutical, the final greenlight Sunday, February 28.

What does that mean for Houston? Mayor Sylvester Turner said the Houston Health Department is also anticipated to be on the list to receive Johnson & Johnson doses within the next seven days.

"That will be a game changer," Turner said at an event on February 28 afternoon. "There will be more vaccines available in a shorter period of time. We anticipate that we will probably get a shipment in sometime this week that will add to the Pfizer [doses] that we are using at NRG."

Turner said other clinics with the Houston Health Department have been administering the Moderna vaccine.

The Johnson & Johnson vaccine does have noticeable differences from the Pfizer and Moderna vaccines, experts said.

The MRNA vaccines each require two shots which are usually delivered weeks apart and stored in freezers. The Johnson & Johnson vaccine is a single shot that can be stored in a refrigerator for up to three months at 35 to 46 degrees.

However, Johnson & Johnson does not have as much of the COVID-19 vaccine produced as originally anticipated. ABC13 confirmed 3.9 million doses will be shipped out across the country this week. Johnson & Johnson announced roughly an additional 16 million doses by the end of the month.

"In the next few weeks, it won't have much of any impact because they only have at least three or four million doses available, and that's disappointing news," says Dr. Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine. "In the longer term, over the next few months, it's really important because we need a greater vaccine supply. We are not going to get there with the two MRNA vaccines. We need probably up to five different vaccines in order to vaccinate the American people."

Recently, there has been a decline in COVID-19 hospitalizations and COVID-19 cases reported statewide. As of Sunday, about 5,700 Texans are in the hospital due to COVID-19, which is half the number of hospitalization in the beginning of the month.

Infectious disease epidemiologist Dr. Catherine Troisi says it's important for people to not let their guard down and that people should get tested if they have been in a high-exposure situation, or if they have been in direct contact with someone who has tested positive.

"Get vaccinated, don't worry about what vaccine it is," Dr. Troisi notes. "It's true that unfortunately there are not as many doses right now of the Johnson & Johnson vaccine as we have hoped, but the company is saying that by the end of June, they will have a 100 million doses, and that's into 100 million people because you don't need two doses.

"So, we expect to have 600 million doses of the other two vaccines, that's 300 million people," she continues. "That should be enough for everyone who wants the vaccine to be able to get it. With one caveat and that is as of right now we do not have a vaccine for children under age 16. Those trials are going on, hopefully as we go throughout the year there will be a vaccine licensed to 12 year-olds and then maybe going down to 8 years or older."

City of Houston launches online registration for free COVID vaccinations

calling the shots

Since COVID-19 vaccinations arrived in Houston, locals have been clamoring for the inoculations. Now, the City of Houston has made it easier for those at highest risk to receive the injections.

The Houston Health Department launched online registration on January 4 for residents at highest risk of coronavirus disease to schedule appointments to receive free vaccinations. (A Spanish version is anticipated to launch as well, according to the city.)

Those in Phase 1B of the State of Texas' vaccine distribution are advised to use the new service. This includes those 65 and older or 18 and older with at least one chronic medical condition putting them at increased risk of severe illness or death.

Frontline healthcare workers — classified as Phase 1A in the distribution plan — who have yet to receive the vaccine also are eligible to sign up to get the shot through the health department, per a press release. The department currently offers the Moderna COVID-19 vaccine. More information can also be found here.

Meanwhile, appointments are also available through the health department's COVID-19 call center by calling 832-393-4220. The call center is open Monday through Saturday from 7:30 am to 4 pm and until 5 pm on Tuesdays and Thursdays.

Users will receive an appointment time and the location of the vaccination clinic site during the registration process. Staffers will screen visitors and direct them to a secure area to receive the vaccination and monitor them for any adverse reaction for 15 minutes, according to the city.

"The Houston Health Department is doing a phenomenal job getting the vaccine directly to people," said Mayor Sylvester Turner. "The new online registration, in addition to the call center, will make the process more efficient. While there is great public demand for the COVID-19 vaccine, there is also a lot of hesitancy. I understand the concerns, but I encourage all eligible Houstonians to get vaccinated to help stop the spread of the deadly virus."

Rice University researchers unveil new model that could sharpen MRI scans

MRI innovation

Researchers at Rice University, in collaboration with Oak Ridge National Laboratory, have developed a new model that could lead to sharper imaging and safer diagnostics using magnetic resonance imaging, or MRI.

In a study recently published in The Journal of Chemical Physics, the team of researchers showed how they used the Fokker-Planck equation to better understand how water molecules respond to contrast agents in a process known as “relaxation.” Previous models only approximated how water molecules relaxed around contrasting agents. However, through this new model, known as the NMR eigenmodes framework, the research team has uncovered the “full physical equations” to explain the process.

“The concept is similar to how a musical chord consists of many notes,” Thiago Pinheiro, the study’s first author, a Rice doctoral graduate in chemical and biomolecular engineering and postdoctoral researcher in the chemical sciences division at Oak Ridge National Laboratory, said in a news release. “Previous models only captured one or two notes, while ours picks up the full harmony.”

According to Rice, the findings could lead to the development and application of new contrast agents for clearer MRIs in medicine and materials science. Beyond MRIs, the NMR relaxation method could also be applied to other areas like battery design and subsurface fluid flow.

“In the present paper, we developed a comprehensive theory to interpret those previous molecular dynamics simulations and experimental findings,” Dilipkumar Asthagiri, a senior computational biomedical scientist in the National Center for Computational Sciences at Oak Ridge National Laboratory, said in the release. ”The theory, however, is general and can be used to understand NMR relaxation in liquids broadly.”

The team has also made its code available as open source to encourage its adoption and further development by the broader scientific community.

“By better modeling the physics of nuclear magnetic resonance relaxation in liquids, we gain a tool that doesn’t just predict but also explains the phenomenon,” Walter Chapman, a professor of chemical and biomolecular engineering at Rice, added in the release. “That is crucial when lives and technologies depend on accurate scientific understanding.”

The study was backed by The Ken Kennedy Institute, Rice Creative Ventures Fund, Robert A. Welch Foundation and Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory.

Houston-area lab grows with focus on mobile diagnostics and predictive medicine

mobile medicine

When it comes to healthcare, access can be a matter of life and death. And for patients in skilled nursing facilities, assisted living or even their own homes, the ability to get timely diagnostic testing is not just a convenience, it’s a necessity.

That’s the problem Principle Health Systems (PHS) set out to solve.

Founded in 2016 in Clear Lake, Texas, PHS began as a conventional laboratory but quickly pivoted to mobile diagnostics, offering everything from core blood work and genetic testing to advanced imaging like ultrasounds, echocardiograms, and X-rays.

“We were approached by a group in a local skilled nursing facility to provide services, and we determined pretty quickly there was a massive need in this area,” says James Dieter, founder, chairman and CEO of PHS. “Turnaround time is imperative. These facilities have an incredibly sick population, and of course, they lack mobility to get the care that they need.”

What makes PHS unique is not only what they do, but where they do it. While they operate one of the largest labs serving skilled nursing facilities in the state, their mobile teams go wherever patients are, whether that’s a nursing home, a private residence or even a correctional facility.

Diagnostics, Dieter says, are at the heart of medical decision-making.

“Seventy to 80 percent of all medical decisions are made from diagnostic results in lab and imaging,” he says. “The diagnostic drives the doctor’s or the provider’s next move. When we recognized a massive slowdown in lab results, we had to innovate to do it faster.”

Innovation at PHS isn’t just about speed; it’s about accessibility and precision.

Chris Light, COO, explains: “For stat testing, we use bedside point-of-care instruments. Our phlebotomists take those into the facilities, test at the bedside, and get results within minutes, rather than waiting days for results to come back from a core lab.”

Scaling a mobile operation across multiple states isn’t simple, but PHS has expanded into nine states, including Texas, Oklahoma, Kansas, Missouri and Arizona. Their model relies on licensed mobile phlebotomists, X-ray technologists and sonographers, all trained to provide high-level care outside traditional hospital settings.

The financial impact for patients is significant. Instead of ambulance rides and ER visits costing thousands, PHS services often cost just a fraction, sometimes only tens or hundreds of dollars.

“Traditionally, without mobile diagnostics, the patient would be loaded into a transportation vehicle, typically an ambulance, and taken to a hospital,” Dieter says. “Our approach is a fraction of the cost but brings care directly to the patients.”

The company has also embraced predictive and personalized medicine, offering genetic tests that guide medication decisions and laboratory tests that predict cognitive decline from conditions like Alzheimer's and Parkinson’s.

“We actively look for complementary services to improve patient outcomes,” Dieter says. “Precision medicine and predictive testing have been a great value-add for our providers.”

Looking to the future, PHS sees mobile healthcare as part of a larger trend toward home-based care.

“There’s an aging population that still lives at home with caretakers,” Dieter explains. “We go into the home every day, whether it’s an apartment, a standalone home, or assisted living. The goal is to meet patients where they are and reduce the need for hospitalization.”

Light highlighted another layer of innovation: predictive guidance.

“We host a lot of data, and labs and imaging drive most treatment decisions,” Light says. “We’re exploring how to deploy diagnostics immediately based on results, eliminating hours of delay and keeping patients healthier longer.”

Ultimately, innovation at PHS isn’t just about technology; it’s about equity.

“There’s an 11-year life expectancy gap between major metro areas and rural Texas,” Dieter says. “Our innovation has been leveling the field, so everyone has access to high-quality diagnostics and care, regardless of where they live.”
