Two new advances in HIV/AIDS prevention and testing could mean big changes for those at-risk of infection. This summer, the Federal Drug Administration offered their approval to new uses of AIDS medicine Truvada and to an at-home HIV test.
Dale Pierce, practice manager and Ryan White Program director at Rosedale ID in Huntersville, says the two new advances offer plenty of hope for prevention. Yet, he describes both as a sort of “double-edged sword.”
Pierce, who is HIV-positive, said his experience taking HIV/AIDS medications played a crucial role when he and his partner, who is HIV-negative, discussed Truvada. His partner had considered using the medicine for its newly-approved prevention method. Known as a pre-exposure prophylaxis, or PrEP, Truvada can be taken daily by an HIV-negative person to help reduce the risk of HIV transmission.
“As someone who has gone through having to take the medications and dealing with its side-effects and how the medicine alters your lifestyle, it wasn’t something we were willing to try,” Pierce says. “At this point, we are more focused on practicing safer sex and being aware of what’s going on.”
Though Pierce and his partner have opted not to use Truvada, he says it can be of practical use to those at-risk. He offers some warning, hoping that the potential reduction in infection risk doesn’t give some a false sense of security. Safer sex practices, he said, are key to prevention.
Pierce says he’s more hopeful about OraQuick, the new at-home HIV test from OraSure. He has his worries — chief among them the availability of medical and psychological counseling in the aftermath of a positive result. Generally, though, the test is a good step toward increasing the availability of HIV testing for more people.
“It is easer access to testing for those people who might be fighting the stigma, who may not want to go to free testing events or the health department,” Pierce says.
At the end of the day, Pierce is glad to see the improvements. But, he’s quick to remind: “There is no 100 percent sure-fire means to stop [HIV] transmission,” he says. Knowledge, awareness and safer sex practices need to be at the forefront of everyone’s mind. : :
