When it comes to HIV prevention, there are several interventions to reduce HIV transmission, some of which are highly effective. As a provider or member of the HIV workforce, you can help guide and teach individuals, both negative and positive, about current HIV prevention methods. HIV transmission risk is further decreased when multiple methods are used in conjunction with one another.
Currently, aside from safer sex (such as using condoms), pre-exposure prophylaxis (PrEP) and treatment as prevention (TasP) are the most widely used and effective HIV prevention methods. PrEP is prescribed to HIV-negative individuals as a pill taken once a day. PrEP is also has effective when taken "on demand," before and after sex, as shown in the IPERGAY study. TasP is also effective because when a person with HIV is on treatment and has an undetectable viral load, their chances of transmitting HIV are virtually eliminated, as shown in the PARTNER study and the HPTN 052 study. In other words, "undetectable = untransmittable."
Other prevention methods, some of which are still only in the research phase, include:
