Antiretroviral therapy (ART) recommended for all with HIV, incl. those with acute/early infection* *Clinical trial data suggest that individuals treated during early infection experience immunologic & virologic benefits refer asap! Genotypic drug resistance testing performed before initiation of ART will guide selection of ART Patients must be willing / able to commit to lifelong treatment with strict adherence Patients may postpone therapy, can be decided on case by case basis Treatment goal suppress plasma HIV 1 RNA levels to undetectable https://aidsinfo.nih.gov/guidelines/html/1/adult and adolescent arv/20/acute andrecent early hiv infection Where to refer HIVAZ.ORG https://www.hivaz.org/ Other HIV considerations Possible exposure Unprotected sex with someone who tells you they have HIV (or you think may have HIV) Condom broke or fell off during sex Rape or sexual assault Work related exposure to HIV (e.g. needle stick injury) Sharing needles to inject any type of drug Post Exposure Prophylaxis (PEP) Must start within 72 hours can call local health department HIVAZ.ORG https://www.hivaz.org/ CDC https://www.cdc.gov/hiv/risk/pep/index.html Pre Exposure Prophylaxis (PrEP) Daily medication, Truvada prescribed by HIV specialist 9
