The United States is experiencing the worst outbreak of West Nile virus since the mosquito-borne disease was first detected in 1999, health officials said Wednesday.

At least 41 people have died so far this summer and health officials have identified a total of 1,118 cases across the country.

For millions of the women around the world cooking the family meal is a daily, dangerous chore. Sweating over smoky open stoves, they put their lives and their children at risk every day.

More than three billion people, or 40 percent of the planet's population, still rely on open fires to cook, balancing a pot on top of some stones, under which burns a fire fueled by wood and coal, dung or left-over crops.

U.S. and South African lawyers are asking a court to allow thousands of miners with lung diseases to sue leading South African gold mining companies they accuse of negligence.

Paul Ryan works out and watches his diet, but a new study shows that clean living can only go so far to help people like the vice presidential candidate overcome a strong family history of heart disease.

The study of 4 million people — the largest ever on heart risks that run in families — found that having a close relative die young of cardiovascular disease doubles a person's odds of developing it by age 50. This risk was independent of other factors like high cholesterol, high blood pressure and diabetes, and was even higher if more than one close family member had died young.

When she was 20 years old, Alphonsina Zara was pregnant with her first child. After three days of excruciating labor, though she was in a health center, her baby was stillborn.

British American Tobacco (BAT) launched an advertising campaign in New Zealand Wednesday opposing plans to introduce plain packaging, in a move the government immediately dismissed as a waste of money.

Women seeking an abortion are seven times more likely to report physical or sexual abuse at the hands of their partners than the U.S. national average for domestic violence, a study published Monday found.

Doctors in Israel are beginning to believe in the power of clowning around.

Over the last few years, Israeli clowns have been popping into hospital operating rooms and intensive care units with balloons and kazoos in hand, teaming up with doctors to develop laughter therapies they say help with disorders ranging from pain to infertility.

As debate rages over the ethics of infant circumcision, a study published Monday said falling rates of the once-routine procedure in the United States could cost billions of dollars in health costs.

"We find that each circumcision not performed will lead to $313 of increased expenditures over that lifetime," said senior investigator Aaron Tobian, of the Johns Hopkins University team that did the study.

As Indonesia shifts from a month of fasting during Ramadan to a week-long eating binge for the Eid al-Fitr Muslim holiday, doctors are braced for an annual spike in complaints of rapid weight gain.
