May 31, 2011 New research findings suggest that a mouse virus thought by some to cause chronic fatigue syndrome is instead a laboratory contaminant. The results led a leading scientific journal to ask for a retraction of an earlier paper proposing the viral link.
May 24, 2011 So far this year, 118 cases of measles have been reported in the United States. Now that may not sound like a whole lot, but that makes this the busiest period for measles since 1996, the Centers for Disease Control and Prevention says.

The armadillo is the only animal, besides humans, that is known to carry leprosy-causing bacteria.
April 28, 2011 Genetic studies have confirmed that some humans handling armadillo meat contracted a never-before-seen strain of the bacterium that causes leprosy. The armadillo is the only animal, besides humans, that is known to carry the bacterium.
April 28, 2011 One new drug to treat hepatitis C won an FDA advisory panel's approval Wednesday, and a second drug is expected to get the green light Thursday. Panelists were highly enthusiastic about the drugs' efficacy, though questions remain about side effects and who will benefit.

April 18, 2011 Measles was declared eliminated in the United States more than 10 years ago, but a few cases still crop up. The biggest problem is travelers who pick up the disease overseas and bring it home.
Honey fell out of favor in the last century as antibiotics became all the rage in medicine.
April 15, 2011 Preliminary research suggests that honey made from the nectar of the New Zealand Manuka tree helps fight drug-resistant bacteria like MRSA. But don't run out and buy some just yet — much more research is needed.
About half of meat and poultry samples nationwide had evidence of S. aureus contamination, a study found.
April 15, 2011 A survey of meat and poultry sold in supermarkets across the country found widespread contamination with Staphylococcus aureus contamination — the cause of most staph infections in people. A quarter of the samples were tainted with bacteria resistant to antibiotics.
Keeping MRSA bacteria like these under control in hospitals remains a challenge.

April 14, 2011 More careful attention to cleanliness in hospitals can help curb infections caused by antibiotic-resistant bacteria. But even stringent hygiene only goes so far in beating the germs back.
A nurse uses an alcohol-based hand gel. A new $1 billion proposal from Health and Human Services aims to cut down on preventable hospital infections and patient readmissions.

April 12, 2011 Health and Human Services Secretary Kathleen Sebelius on Tuesday pledged "up to $1 billion" for a new initiative that aims to reduce preventable hospital infections and patient readmissions after discharge. Many in the health industry are praising the proposal — but GOP lawmakers aren't, perhaps because it's paid for by the health overhaul law.
