New coronavirus cases and hospitalizations are both on the rise in the Greater Houston area, according to new data from the Texas Medical Center released Dec. 27.

More than 5,000 people tested positive for COVID-19 in the Houston area Dec. 26, according to TMC data. An average of 2,094 new cases were recorded per day over the last week, according to TMC data. Over that same time, an average of 201 new COVID-19 patients were admitted into TMC hospitals per day, an 82% increase over the previous week.

In the same span of time, nearly 4,000 COVID-19 vaccine doses were being administered per day at TMC institutions.

The uptick in cases comes as researchers with the Baylor College of Medicine published a study potentially linking COVID-19 to oxidative stress/oxidant damage and glutathione deficiency in adults ages 21-40.

More than 63% of Harris County’s eligible population—which includes everyone age 5 and older—is fully vaccinated, according to the Texas Department of State Health Services. More than 73% of those residents have received at least one dose of the vaccine.
