Richard Knox

Since he joined NPR in 2000, Knox has covered a broad range of issues and events in public health, medicine, and science. His reports can be heard on NPR's Morning Edition, All Things Considered, Weekend Edition, Talk of the Nation, and newscasts.

Among other things, Knox's NPR reports have examined the impact of HIV/AIDS in Africa, North America, and the Caribbean; anthrax terrorism; smallpox and other bioterrorism preparedness issues; the rising cost of medical care; early detection of lung cancer; community caregiving; music and the brain; and the SARS epidemic.

Before joining NPR, Knox covered medicine and health for The Boston Globe. His award-winning 1995 articles on medical errors are considered landmarks in the national movement to prevent medical mistakes. Knox is a graduate of the University of Illinois and Columbia University. He has held yearlong fellowships at Stanford and Harvard Universities, and is the author of a 1993 book on Germany's health care system.

He and his wife Jean, an editor, live in Boston. They have two daughters.

More than 12 million Americans buy health insurance on their own, and many are getting cancellation notices because their individual coverage does not meet the standards of the Affordable Care Act. This is causing anxiety and anger — especially since most of these people can't get onto the healthcare.gov website to figure out their options for 2014.

Today marks a milestone on the nation's long march toward universal health coverage: the launch of online marketplaces, called exchanges, designed to help people find insurance they can afford.

It's an idea pioneered by Massachusetts seven years ago. People here call their program a success, and say the state's exchange was an indispensable factor.

Researchers say a cheap, generic pill called finasteride prevents almost 40 percent of low-grade prostate cancers without increasing the risk of dying from more aggressive tumors.

New evidence points to the drug as a potentially safer way to deal with prostate cancers that now get more intense treatment. Many prostate cancers that aren't destined to cause men serious health problems are often treated with surgery or radiation.

A federal task force is planning to recommend that millions of smokers and former smokers get a CT scan annually to look for early signs of lung cancer.

The 16-member US Preventive Services Task Force gives that lung cancer screening test a grade of B, which puts it on the same level as mammography for women between the ages of 50 and 74.

Looking crisp and official in his khaki-colored sheriff's department polo shirt, Steve Steinhardt says Sheboygan, Wis., is a pretty good place to be a director of emergency services.

"Nothing bad happens here," he says, knocking on wood. Unless, that is, you count the tuberculosis outbreak that struck the orderly Midwestern city of 50,000 this spring and summer.

"I never expected TB to be one of the bigger emergencies I'd face when I got into this field," Steinhardt says.

A vaccine against human papillomavirus — the most common sexually transmitted infection and the cause of almost all cervical cancer — is dramatically reducing the prevalence of HPV in teenage girls.

The first vaccine against HPV, Merck's Gardasil, was approved by the Food and Drug Administration in 2006. Cerverix, from GlaxoSmithKline, was approved in 2009.

The World Health Organization is warning health care workers everywhere to suspect a disease called Middle Eastern Respiratory Syndrome, or MERS, whenever they see a case of unexplained pneumonia.

Monday's warning comes at the end of a six-day WHO investigation in Saudi Arabia, where 40 of the 55 cases of the respiratory disease have occurred. Sixty percent of those people with known infections died.

Every day in hospitals all over America, thousands of patients die of infections that used to be curable. But the antibiotics used to treat them aren't working anymore.

It's called drug resistance, and it's largely a consequence of antibiotics overuse. The more germs are exposed to antibiotics, the faster they mutate to evade being vanquished.

Thanks to gold-standard tuberculosis treatment and prevention programs, cases of TB in the United States have declined every year for the past two decades — to the lowest level ever.

But TB's course through the Williams family in Boston shows that no nation can afford to relax its efforts to find, treat and prevent TB. It's just too sneaky and stubborn an adversary.

The number of Boston bombing victims still in the hospital dropped to 19 as of Wednesday evening. The great majority have gone home or to a rehab facility.

That's what has happened with Celeste and Sydney Corcoran, a mother-daughter pair who ended up in the same hospital room after being struck down by the first marathon bomb blast.
