City launches public dashboard for tracking COVID-19 in Houston's wastewater

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.

Melax Tech Partners, a leader in natural language technology processing, announced a new partnership with the University of California at Irvine that will help researchers derive insights from the UCI Health Data Science Platform’s electronic health records system and improve patient care.

Melax will implement its signature text annotation tool LANN to pull information from clinical notes, and its CLAMP product to develop natural language processing customizations through the use of AI, according to a statement from the company.

“There has been a strong desire among UCI researchers to have the capability to analyze free-text clinical narrative data using cutting-edge NLP technologies," Kai Zheng, chief research information officer at UCI Health Affairs, says in a statement. "We are delighted to have this opportunity to work with Melax Tech to deploy their AI-driven annotation and analytics tools to help our researchers advance their research agenda by leveraging the vast amount of free-text data that our health system has accumulated in the past two decades.”

Natural language processing, or NLP, allows organizations and healthcare groups to sift through and analyze massive amounts of data at a rapid rate through the use of machine learning and AI. Houston-based Melax Tech, founded in 2017, has developed multiple NLP tools that are used by more than 650 health care and life science organizations, according to its website.

In addition to the recent partnership with UC Irvine, Melax has also recently partnered with Vanderbilt University Medical Center and the University of Western Pennsylvania on similar clinical projects.

Melax has also used its platforms to pull vital information from datasets relating to COVID-19, in both medical and social settings.

In March 2022, it was awarded a Phase 1 NIH Award, valued at $300,000, to develop informatics tools based on COVID-19 datasets with the San Diego Supercomputer Center at UC San Diego. The tool aims to help researchers better understand vast amounts of virus-related data and connect findings with other similar results.

In August, Melax also received another $300,000 grant from the National Institute of Allergy and Infectious Diseases to develop NLP-based algorithms that will "model, extract and synthesize vaccine misinformation from multiple popular social media sources," according to a statement. Melax will also develop a visualization that presents its findings on the misinformation into a compressible format.

"This is a very real topic affecting culture at present," Andre Pontin, CEO at Melax Tech, says in a statement. "And shows that we as a collective business and group of experts continue to be on the cutting-edge of science in the NLP and AI domain."
