How safe do you think is this Strategy to protect against HIV. It's in a purely heterosexual context, the partner is female. - Ask every sex partner when they had fever the last time. If any longer fever period in the last 3 months be careful since it could indicate an Acute HIV Infection. - Ask how often condoms were used in the recent time. - Test every partner with a Home Test Rapid Test (from idiagnosticsco.com). It's a blood based test, results in 15 minutes, 99% accuracy and approved by WHO/Unicef but not FDA. - Most people develop detectable antibodies after 4 weeks - Most people have Acute HIV Infection 2-4 weeks after infection, for an average of 28 days. So if she had fever/flu like symptoms recently or tests positive stay away. Otherwise it should be safe to have ORAL and VAGINAL sex without condom. NO ANAL. Given all the tests above we can assume she is HIV negative. Should she be HIV positive the risk for infection is actually very low, that is 0.5 / 10.000 or 5 / 10.000 per exposure. So that's less than 0.1% per sex act - should the test not work or something. Condoms are 85% effective. How effective is my strategy? What do you think?
