Thank you doctor
I was given oral sex by a prostitute (with blow job), I had sperm in her mouth. Six bad washed his genitals and checked that my genitals were not bleeding. Then 2 weeks later I had fever, diarrhea, night sweats, nausea,.... At 28 days (4 weeks) I went for an HIV test (rapid test) with negative sperm results and syphilis test. negative results. I want to ask, can I feel secure about the risk of HIV infection? Is a negative rapid test result of 28 days valid (trusted)? Thank you doctor.
Oral sex is not a risk for HIV. Air and saliva inactivate the virus. You did not need to test AT ALL. The only risks for HIV are to have unprotected vaginal or anal sex or share IV needles to inject drugs. NO risk. No need to test. EVERY test you take will be negative and accurate because you have to have a risk to get HIV.
For information purposes though, 4th generation test are accurate and conclusive 28 days post event.
