Researchers are moving closer to fully curing HIV by designing a more accurate, cost effective, and efficient test for detecting how much of the virus is left in the human body.

The greatest challenge for researchers who have been hard at work trying to come up with a cure for HIV is detecting the virus after retroviral therapy. HIV can “hide” in immune cells at levels that are hard to identify.

Current anti-HIV therapy suppresses the infection to an almost undetectable level, but the virus can persist in a dormant form in CD4 T cells, which are also called T cells or T helper cells. However, most of the HIV DNA in these cells is defective and cannot cause infection.
