HOUSSEN, Alsace, France -- Here in the village from where my great-great grandparents emigrated to America, in the former province known as Alsace, those who derive their living from the land are now a fraction of what they were at the time my ancestors left in 1872. But many, including...

NAIROBI, Kenya -- The abortion issue in Kenya is raucous, rancorous and highly emotional and political, just like in the U.S., but there is one major difference: In Kenya, abortion rights have been liberalized in certain cases in a Constitution approved in a public referendum two years ago.

At the XIX International AIDS Conference (AIDS 2012) in Washington, DC this week, there will be -- justifiably -- much talk about the significant scientific advances in the fight against HIV/AIDS of the last two years, and how we cannot squander this unprecedented opportunity to break the back of the...

This year's G8 Summit took place at the secluded Camp David presidential retreat in the mountains of northern Maryland.

GENEVA, Switzerland -- This month I was visiting the Strategic Health Operations Centre (SHOC), deep inside the World Health Organization.

One night, as a young development worker in Mali 20 years ago, I engaged in high-risk behavior in a village west of Bamako -- I slept without a mosquito net in the middle of the rainy season.

I came to regret my lapse: I was struck down with a severe...

Pope Benedict XVI's comments last month that condom use can be justified in some cases to help curb the spread of AIDS were surprising to me only because they came from the very top of the Catholic Church. But in my 10 years of managing condom social marketing programs for...
