Public health workers have two main tools for HIV screening: a blood test that detects HIV a couple weeks after infection or a saliva test that detects the virus more than a month after infection. With a trick of chemistry, however, scientists at Stanford University have combined the best attributes of both — and the result could mean a serious boost for HIV prevention.

Study: New method of mapping HIV transmission risk may be more efficient way to prevent infection
Ideally, everyone should be tested for HIV. In reality, however, only about half of U.S. adults have ever been tested for HIV and about half of the 50,000 new infections that happen every year in the U.S. are transmitted by people who are unaware of their HIV status. Such statistics recently led a group of researchers to ask if there’s a more efficient way to go about curbing the HIV epidemic.
