The Louisville AIDS Walk is Sunday, but donations for this year's event have fallen short.Last year, the AIDS Walk raised about 200 thousand dollars. About a quarter of which was donated in the days leading up to the event.So far this year, one hundred thousand dollars has been raised. Director Brad Hampton attributes the drop to the economy and waning interest in AIDS-related issues."HIV-AIDS is just not in the forefront of concern of Louisvillians anymore," he says. "There's a misconception that AIDS is no longer a crisis, that you just take one pill a day and everything's okay. It's just really not to that point yet."Hampton says if more money isn't donated by January 1st, the AIDS Walk will have to cut services it funds for patients next year.
