It's been 25 years since the first AIDS diagnosis. On June 5, 1981, the CDC publication Morbidity and Mortality Weekly Report printed a report entitled "Pneumocystis Pneumonia --- Los Angeles" -- a report that turned out to be the first scientific report of what is now known as AIDS. Join Ira and guests in this hour of Science Friday for a look at AIDS at 25 -- from treatments that keep the disease in check, to prevention programs, to the changing face of AIDS. Is there any hope on the horizon?

Plus, a new report from the United Nations finds that the epidemic may be slowing globally, but is increasing in some countries. The report finds an estimated 38.6 million people are living with HIV, the virus that causes AIDS, around the world. 4.1 million people are estimated to have become infected last year. And while the researchers found improvements in AIDS education around the world, increased condom use, and improved rates of HIV testing, they say that much more still must be done to stem the tide of the global HIV epidemic. We'll talk to one of the researchers abotu the new data. Call in with your questions and comments at 1-800-989-8255 (3-4 Eastern). Teachers, find more information about using Science Friday as a classroom resource in the Kids' Connection.
