Twenty-eight years ago, Tracy Dixon-Salazaar woke to the sound of her daughter, two-year-old Savannah, in the midst of a medical emergency.

“I entered [Savannah’s room] to see her tiny little body jerking about violently in her bed,” Tracy said in an interview. “I thought she was choking.” When she and her husband frantically called 911, the paramedic told them it was likely that Savannah had had a seizure—a term neither Tracy nor her husband had ever heard before.

A vaccine for Lyme disease could be coming. But will patients accept it?

Hiking is one of Marci Flory's favorite activities, but her chronic Lyme disease sometimes renders her unable to walk. Biotech companies Pfizer and Valneva are testing a vaccine for Lyme disease in a Phase III clinical trial.

Marci Flory

For more than two decades, Marci Flory, a 40-year-old emergency room nurse from Lawrence, Kan., has battled the recurring symptoms of chronic Lyme disease, an illness which she believes began after being bitten by a tick during her teenage years.

Over the years, Flory has been plagued by an array of mysterious ailments, ranging from fatigue to crippling pain in her eyes, joints and neck, and even postural tachycardia syndrome or PoTS, an abnormal increase in heart rate after sitting up or standing. Ten years ago, she began to experience the onset of neurological symptoms which ranged from brain fog to sudden headaches, and strange episodes of leg weakness which would leave her unable to walk.

Scientists forecast new disease outbreaks

A mosquito under the microscope.

Two years, six million deaths and still counting, scientists are searching for answers to prevent another COVID-19-like tragedy from ever occurring again. And it’s a gargantuan task.

Our disturbed ecosystems are creating more favorable conditions for the spread of infectious disease. Global warming, deforestation, rising sea levels and flooding have contributed to a rise in mosquito-borne infections and longer tick seasons. Disease-carrying animals are in closer range to other species and humans as they migrate to escape the heat. Bats are thought to have carried the SARS-CoV-2 virus to Wuhan, either directly or through another host animal, but thousands of novel viruses are lurking within other wild creatures.

Understanding how climate change contributes to the spread of disease is critical in predicting and thwarting future calamities. But the problem is that predictive models aren’t yet where they need to be for forecasting with certainty beyond the next year, as we could for weather, for instance.
