HIV/AIDS Virus (09:34)

FREE PREVIEW

Doctors and researchers have struggled to understand and treat HIV and AIDS since it first appeared in the 1980s. People with a non-specific immunity to the HIV virus can survive without developing AIDS. Researchers in San Francisco are working to isolate a protein that stops the virus from progressing.

Understanding HIV (04:25)

The HIV/AIDS virus is able to enter human cells that have the CD4 protein and a code receptor that was unknown to researchers. Two co-receptors were discovered and helped researchers understand why some people are infected with the virus.

HIV/AIDS Vaccine Problems (06:01)

The HIV/AIDS virus does not respond to the two normal methods of vaccination. The virus is constantly mutating, which makes developing a vaccine difficult. Researchers are working to create a DNA vaccine.

AIDS Crisis (06:32)

More than 25 million people in Sub-Saharan Africa have HIV/AIDS, but cannot afford treatment. Social and cultural issues can make prevention and treatment difficult throughout the world.
