  • As waves of omicron and its extremely contagious subvariants burn through previously uninfected populations, it has become clear that people with mild or asymptomatic cases aren’t immune from long COVID. Host Bonnie Petrie talked to Dr. Monica Verduzco Gutierrez, professor and distinguished chair of Rehabilitation Medicine at the University of Texas Health Science Center in San Antonio, to learn what we know about post-COVID syndrome and what we need to do to prepare for the decades of disability that may remain long after the pandemic is in the rear view.
  • COVID-19 testing clinics around the country are closing, and federal funding for free clinical testing is drying up. But wastewater surveillance could step in to play a crucial role in keeping track of where the virus is and just how much is really circulating out there. In this episode, host Bonnie Petrie takes us to a wastewater treatment plant in Converse, Texas and talks to scientists trying to build a surveillance and sequencing program in South Texas.
  • Ashley Savidge Hernandez, a Marine Corps spouse and mother of five, delivered a baby while critically ill with COVID-19. How did she and her healthy son Kyzon survive the worst that COVID has to offer?
  • Dr. Peter Hotez has become one of the faces of the pandemic. The bow-tied Texas scientist has been all over radio and television — and on this podcast, too — explaining viruses generally and COVID-19 specifically. Now Hotez and his partner, PhD scientist Maria Elena Bottazzi, have developed a vaccine that would be cheap and easy to produce.

  • New research out of South Africa and the UK have found that the omicron variant dramatically reduces vaccine effectiveness in the Pfizer-BioNTech COVID-19 vaccine. However, there are ways to minimize omicron's impact in the United States.
  • Children between 5 and 11 are now eligible for the Pfizer-BioNTech COVID-19 vaccine. Is the vaccine safe for people in this age group? Does it work? What are the potential side effects? We ask an epidemiologist and a pediatrician those questions and much more.
  • A new podcast from Texas Public Radio explores the confusion, heartbreak, and joy of moving back home to care for an aging relative. It's hosted by longtime NPR journalist Kitty Eisele, who chronicles her journey caring for her dad and the conversations she has with friends and experts along the way. You can listen to the first five episodes of "Demented" on Apple Podcasts, Spotify, Stitcher, or anywhere you listen to podcasts.
