Lifewatch: HIV

WILMINGTON -- More than a million people in the United States live with HIV, the virus that causes Aids.

New research is making treatment even more effective and providing important new clues about the disease itself.

Today there are more than 25 drugs to help people with HIV and Aids live longer.  But that's not enough.

The drugs that make living with Aids possible come with a catch.  Not every drug combination works for every patient.  Researchers at Duke University have developed a critical test that provides an early warning of which medicines a patient will be resistant to.

At the University of Florida, researchers are taking a different approach.  They are studying blood samples from young HIV patients over several years.  They tracked the virus' movements and genetic changes.  These led to clues that could one day tell them where and how to stop it.

According to researchers, the next step is tracking how HIV evolve before and during treatment, information that could pave the way for new drugs to fight the virus.
