Thirty years after the CDC confirmed the first cases of HIV, millions have died, particularly in developing nations. But there's hope. Innovative HIV prevention programs -- including a peer education program from hair stylists in Zimbabwe and a media campaign promoting male circumcision in Africa -- are contributing to a decrease in the global rate of new HIV infections.

These and other stories of effective programs on the ground in developing nations are showcased in a new TV documentary, ViewChange: HIV Prevention - Looking Back & Moving Forward, that premieres on Friday, July 29, from Link TV and international global health organization PSI (Population Services International). Debra Messing, actor and PSI ambassador, narrates the half-hour show.

We hope you'll join us in marking this key milestone, and that you'll spread the word about what's working in global HIV prevention.

(Al Jazeera English: 0125 PT, May 13, 2011) The fight for global access to anti-Aids drugs has been given added urgency as a research study found that people with HIV who start taking anti-retroviral drugs early can dramatically reduce the danger of passing the virus to their partners.

South Africa's new president Jacob Zuma assumed power this week with no shortage of controversy trailing him. Derided over the years as a terrorist, a communist, and an uneducated polygamist, Zuma arrived at the presidency having recently beaten back charges of rape and corruption. Free market devotees worry that Zuma will unravel South Africa's free trade policies. And on the left, observers are clamoring for the former freedom figher and long-time ANC leader to address the nation's epidemic poverty, crime, and HIV/AIDS infection rates.

But with all the speculation of dramatic change, Zuma's first week can't but seem a bit anticlimactic. Saturday's inauguration ceremony was marked by the appearance of Nelson Mandela to whom Zuma kneeled before addressing the nation. Zuma's midweek cabinet selection provided hope to both partisans on the right and left and pleased a broad cross-section of the South African press. Even the Mail & Guardian cartoonist Zapiro, a long-time Zuma satirist, agreed to depict the new president in a more conciliatory light.

Still, South Africa's inaugural week was not without its controversy. Opposition leader Helen Zille accused Zuma of putting his three wives at risk of contracting HIV and therefore was unfit to tackle social policy. BBC News further published a report that detailed Zuma's use of the nation's growing spy services, particularly for his defense against corruption charges.

Will Zuma prove to be a leader to unite South Africa? Or will critics prove justified in their skepticism of his ability to lead?
