The government has named 75 medical facilities that received a potentially contaminated drug suspected of infecting 47 patients with meningitis nationwide.

It now appears that the new coronavirus found on the Arabian Peninsula is more widespread than initially thought, even though only two people are known to have gotten sick from it.

At first it seemed likely that the two known cases of illness from the new cousin-of-SARS virus may have been exposed in or near the Saudi Arabian city of Jeddah on the Red Sea coast.

It's a troubling story authorities think will unfold over the next month or so. An untold number of Americans who got steroid injections in their spine to relieve back pain may end up with a rare fungal meningitis. The drug was contaminated with the spores of a common leaf mold — nobody knows how.

So far, the Centers for Disease Control and Prevention has recorded 35 cases of the fungal meningitis in six states: Tennessee, North Carolina, Florida, Virginia, Maryland and Indiana. Five patients have died.

Scientists have recently discovered three new human viruses.

Should you take Vitamin D supplements to prevent colds and shorten the misery?

Like other theories about the benefits of vitamin D, it seems like a reasonably good idea. After all, some lab studies suggest vitamin D might enhance immunity. And as everybody knows, people are more prone to respiratory infections during winter, when they cover up and get less vitamin D-generating sunlight.

New viruses are popping up all over these days – Heartland virus in Missouri last month, a new virus in the same family as SARS in Saudi Arabia this month. And now, a never-before-seen hemorrhagic fever virus in central Africa.

Brief counseling from primary care doctors reduces "risky" drinking, defined as having more than four drinks a day for men, three for women, a federal task force says.

About one in three Americans misuse alcohol, the panel says, with the vast majority falling in the "risky" category.

Scientists have known for a while that breast cancer is really four different diseases, with subtypes among them, an insight that has helped improve treatment for some women.

But experts haven't understood much about how these four types differ. A new report, published online in the journal Nature, provides a big leap in that understanding.

A Swedish medical team has transplanted uteruses from two women in their 50s to their daughters. Meanwhile, Shots has learned that an Indiana group is recruiting women willing to undergo womb transplants in this country.

"We could go ahead tomorrow if we found the perfect candidate," Dr. Giuseppe Del Priore told Shots.

A lot of medicine's direst emergencies come down to one problem: lack of oxygen.

Cardiologist John Kheir started thinking about that when a little girl in his care, drowning from lung hemorrhages, died before she could be hooked up to a heart-lung machine that would have kept her blood oxygenated while the damage was repaired.
