Fifteen years ago an unwelcome viral visitor entered the U.S., and we've been paying for it ever since.
The U.S recorded its first case of West Nile virus back in 1999. Since then, the disease has spread across the lower 48 states and cost the country around $800 million, scientists reported this week in the American Journal of Tropical Medicine and Hygiene.
The Obama administration is, again, delaying implementation of a part of the Affordable Care Act that requires employers to provide health insurance to their workers (or, potentially, face penalties).

It's been a big week for distressing and important news about women and stroke.
Thursday saw the first-ever guidelines for prevention of stroke in women. They pointed out that women are more likely than men to have strokes. Young women are vulnerable because of pregnancy and birth control pills.

People who have slightly higher blood pressure when they're 18 to 25 are more likely to have high blood pressure and hardening of the arteries in their 40s, a study says. About one quarter of the people in this study were in that group.
When it comes to persuading teenagers not to smoke, you have to think short-term, the Food and Drug Administration says.
"While most teens understand the serious health risks associated with tobacco use, they often don't believe the long-term consequences will ever apply to them," FDA Commissioner Margaret Hamburg told reporters Monday before unveiling the agency's first-ever anti-smoking campaign.
Sure, you think, my kid's on a football team. That takes care of his exercise needs, right? Probably not.
"There are these bursts of activity," says Jim Sallis, a professor of family and preventive medicine at the University of California, San Diego. "But if you think about it, one hour of playing football out on the field means that the vast majority of that time is spent standing around waiting for the next play."
