What are the biggest threats to the health security of the American people? There are some strong candidates. Avian influenza is spreading in birds, cattle, and 50 mammalian species. Measles cases are surging at home and abroad. COVID-19 is still spreading and could mutate into a more deadly strain. Farther afield, Uganda continues to respond to an Ebola outbreak and Mpox has been seen in 127 countries. But perhaps the biggest threat to America’s health could be self-inflicted.

PFAS can be found in just about everything, but there are a few things you can do to reduce your exposure.

Over the coming months, more than 100,000 Americans will likely die, mostly unnecessarily, from respiratory infections. Yes, that is the reality we are now facing this fall and winter—and likely every fall and winter for the foreseeable future. Unless we act.

COVID cases are on the rise and this week the Centers for Disease Control and Prevention has recommended that anyone who is six months or older get the new COVID-19 vaccines. Health reporter Lynn Arditi talked about the new vaccines with Doctor Ashish Jha, former White House COVID advisor and current dean of Brown University’s School of Public Health.

Noise pollution is a physical and mental stressor with real health impacts, Professor Erica Walker tells NPR. "It's going to the emergency room for a panic attack, it's 'I can't sleep,' 'I can't hear my children.' It's all of those things," she says.

The health effects of chemical pollutants called “forever chemicals” are becoming indisputable, says epidemiologist Joseph Braun.

“Although the reported number of cases in the U.S. is now over 100,000 per day, the real number is clearly orders of magnitude higher,” Brown University School of Public Health epidemiologist Mark Lurie told The Journal. “We are clearly experiencing the next wave; who among us doesn't know multiple people who have been infected during this wave?”

Epidemiologist Erica Walker returns home to study the environmental quality of Jackson, Mississippi.

The founder of the Community Noise Lab will partner with the Piney Woods School on a Robert Wood Johnson Foundation-funded study of the air, noise, and water quality of the Jackson, Mississippi Metro area.
