They discussed 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.

The emergence of the delta variant has presented a daunting challenge in the fight against the COVID virus, made worse by a pandemic of bad information. Much of that bad information is being spread intentionally by people who know it's false; it's disinformation. People across the country consume that disinformation and — believing it's true — pass it on. In this episode of Petrie Dish, we explore the medical misinformation and disinformation that are fueling anti-mask and anti-vaccine beliefs that are driving the delta surge.

COVID-19 and pregnancy are not a good mix. In this episode of Petrie Dish, Bonnie Petrie explores the risks associated with getting COVID during pregnancy and why doctors are recommending that people who are pregnant get a COVID vaccine.

As of May 13, nearly 120 million Americans are fully vaccinated, and the Centers for Disease Control and Prevention released new guidance saying anyone who is fully vaccinated can take off their masks in most situations, outside and inside.For many in the United States it can feel like the pandemic is over, but many people across the country remain unvaccinated and COVID surges are still happening across the globe. This week's Petrie Dish takes a look at the state of the pandemic.

The Food and Drug Administration and the Centers for Disease Control have asked vaccine administrators to stop using the Johnson & Johnson one-dose COVID-19 vaccine. The federal agencies called for this pause after six women experienced dangerous blood clots after getting the J&J shot. Dr. Ruth Berggren is an infectious diseases doctor and the director of the Center for Medical Humanities and Ethics at UT Health San Antonio. She says this recommended pause is appropriate, but stresses that the reports of blood clots in those who’ve received the J&J shot are exceedingly rare.

The pandemic has not been easy on children. TPR's Bonnie Petrie spoke with a renowned pediatrician about how to help them overcome the individual and collective trauma of the last year.

Dr. Ricardo Cigarroa is a cardiologist in Laredo. He descends from a line of doctors in the city who have been serving patients there for 100 years.

Dr. Katelyn Jetelina is an epidemiologist at UT Health’s School of Public Health in Dallas. She said there are about 12,000 strains of SARS-CoV-2 circulating around the world right now. One of them — the UK variant — is likely to become the dominant strain in the U.S. by March.

The pandemic has killed hundreds of thousands of Americans, but it's also stolen our normal lives and our sense of security. How do we go on when pressed under the weight of so much personal and collective pain? This week's Petrie Dish explores pandemic grief and also considers ideas about how to transform that pain into resilience.

The worst time of the year for viruses is at our doorstep. During the winter there are surges in adenoviruses, respiratory syncytial viruses — more commonly known as RSV — mild coronaviruses that cause colds, basically all the cold and flu-like illnesses you’d expect when the weather turns cold. And, of course, the actual flu, which can be an efficient killer in its own right.

On this week’s Petrie Dish, we explore what happened in Louisiana and Southeast Texas when Hurricane Laura landed — and what other hurricane hotspots like Florida, Alabama and Mississippi can learn from the deadly storm.

On this week’s Petrie Dish, we dive into the COVID-19 vaccine. First we answer: what is a vaccine? We've all gotten them, but have you ever wondered how they protect you from disease?

COVID-19 has exposed all Americans to an increased risk, even while doing the most mundane things: shopping at the grocery store, going to work, and taking walks. But it’s also exposed how communities of color are largely defenseless in the fight against an enemy that does not discriminate, but rather reveals to us our own discrimination.

In the last two weeks, some Texas counties implemented new face mask orders and Gov. Greg Abbott ordered all bars to shut down — before eventually issuing his own statewide mask order.

At first, COVID-19 appeared to be primarily a respiratory disease. But patients have reported a much wider range of symptoms than most viral diseases, leading some researchers to wonder if COVID-19 might, in some cases, also be a vascular disease. On this episode of Petrie Dish, TPR's podcast about the science of the pandemic, we explore the evidence for this and hear from coronavirus survivors experiencing the vascular side effects of the disease.

As restaurants reopened and businesses relaxed mask-wearing rules, coronavirus hospitalizations have spiked in parts of the country that previously escaped the worst of the pandemic. This week on Petrie Dish, Texas Public Radio's podcast on the science of the pandemic, we take stock of one such state, Texas, and ask whether reopening the economy worked the way it was supposed to.

Covid-19 survivors must adjust to a wide array of lingering symptoms — could those side effects last a lifetime? This week on Petrie Dish, TPR's podcast about the science of the pandemic, two survivors tell their stories of halting recovery, and experts weigh in on what we know — and don't know — about the impact of the coronavirus on the body.

To rein in the invisible spread of the virus, a special branch of science has exploded: Contact tracing. It's the careful, sometimes intimate task of figuring out where the coronavirus might have spread in a community, and who is at risk. This week on Petrie Dish, TPR's podcast about the science of the pandemic, we hear from the disease detectives who are tracking down possible Covid-19 carriers before they even get sick. We also dig into state-by-state plans to ramp up contact tracing to safely restart the economy, and compare U.S. contact tracing efforts with those across the world.

A huge swath of the American workforce is unable to work from home, and the repercussions of a crowded workplace, rather than one that is social-distanced, are gradually becoming clear.

Creating a brand-new drug is painstaking and tricky — under normal circumstances. In the age of coronavirus, drug researchers are working in overdrive. This week on Petrie Dish, TPR's explainer podcast about the virus pandemic, we hear from the experts trying to balance safety and speed in their search for a cure, and from a woman who suffered the side effects from that search.

If you’re diagnosed with COVID-19, one of your first conversations will likely be with a nurse. And during your journey to recovery, nurses will be stationed at your side every step of the way. This week on Petrie Dish, TPR's weekly show on the coronavirus, nurses describe how they're adjusting to this sudden new role in the front lines of the crisis.

Almost overnight, "flatten the curve" became a national motto. This week on Petrie Dish, TPR's weekly podcast about the coronavirus, we unpack the origins of that phrase with a public health expert who helped popularize it. And, we hear from reporters across Texas about some of the negative consequences of quarantine, from a spike in domestic violence reports to the relocation of migrants in camps along the U.S.-Mexico border.

In the span of a few weeks, a medical device most of us have never seen or used became a national concern, the signature shortage in our response to the COVID-19 outbreak. This week on Petrie Dish, TPR's explainer podcast about the coronavirus pandemic, we explore how the coronavirus affects the lungs and how our government, our hospitals, and industrious YouTubers are responding to the vast shortage of ventilators.

The virus sweeping across the planet right now is frightening, in part, because there is so much we don't know about it. In the first episode of Petrie Dish, TPR's explainer podcast about the coronavirus pandemic, Bonnie Petrie talks to a virologist about what exactly the coronavirus is and how scientists are studying it.

Stay tuned for a new podcast about how the coronavirus is changing our world, with Texas Public Radio Bioscience-Medicine reporter Bonnie Petrie.
