July 22, 2012 The country has the largest HIV epidemic in the world, and it's also had one of the most conflicted responses to the virus. For years, the government questioned the link between HIV and AIDS and offered little by way of treatment. Now, South Africa is trying to make up for lost time.
July 20, 2012 When other countries were struggling to deal with the HIV epidemic, Brazil openly acknowledged the problem and launched aggressive campaigns to raise awareness and treat the disease. But activists now say say there are no longer organized HIV prevention efforts.
July 19, 2012 Each year hundreds of thousands South Africans become infected with HIV, so it might seem that a drug to slow transmission would be welcome. But there's concern about unintended consequences if Truvada is used widely for prevention.
July 19, 2012 Clinicians on the front lines say HIV treatment could help end the AIDS pandemic by curbing infections. Studies have found that HIV drugs make a person less likely to transmit the virus to others because they decrease the level of virus in the body.
July 17, 2012 Some Brazilian researchers say Truvada should only be given to very specific groups at risk of getting HIV, like young, gay men. Others are concerned that a drug that blocks the transmission of HIV could be a set-back for safe sex campaigns and might actually encourage unsafe sexual behavior.
July 9, 2012 Botswana's successful efforts against AIDS mean more HIV-positive children than ever are living into adolescence. But that brings with it new challenges, as kids who've been on antiretroviral drugs their whole lives enter the tumult of the teenage years — and face the specter of drug-resistant mutations.
July 6, 2012 HIV rates among men who have gay sex in Kenya are three times higher than the national average. To curb those high transmission rates, health workers must first convince gay men to be open about their sex lives in a country where coming out of the closet can mean discrimination, violence and even jail.
July 5, 2012 By the end of 2013, Kenyan health officials want more than 1 million men to get circumcised — a procedure that can reduce the risk of contracting HIV by up to 60 percent. If the effort succeeds, it just might prove a model for the rest of Africa.
April 16, 2012 A major expansion of the Panama Canal is fueling the tiny Central American country's economy. Last year, Panama's economy grew by more than 10 percent. But with roughly one-third of the country's people living in poverty, critics say the growth is primarily benefiting a small elite.
April 4, 2012 The Panama Canal is getting its first major overhaul since it was opened nearly a century ago. The massive construction project will add a third channel that will permit many more ships, and much larger ones, to take the shortcut between the Pacific and Atlantic Oceans.
March 24, 2012 The throngs of well-wishers stretched for miles along the highway from the airport when Pope Benedict XVI arrived Friday. The pontiff comes during a presidential campaign and amidst a brutal drug war that's terrified and desensitized much of the country.
February 27, 2012 Drug cartel violence, riots and fires have killed more than 400 inmates in Mexican and Central American prisons recently. The deaths underscore the problems of corruption, overcrowding, prison gangs and crumbling infrastructure that prisons face throughout the region.
