Dear Dr. Bob,

First of all, thank you for your thoughtful and postive approach to this very sensitive subject. I've read several of your responses and am much impressed by your answers.

About 16 weeks ago I had protected (I didn't notice any breakage)vaginal intercourse with a sex worker in West Africa. After 13 weeks of worry and feeling very disappointed in myself, I tested negative on both hiv1 and hiv2 elisa tests. My question is, due to the prevalence of hiv among sex workers in that region, would you reccomend testing out to six months? Also, I read in one of your responses that the hiv1 O subtype is more common in that region. Do I need to ask for this test specifically?

Thanks for all that you do. I'll be making a donation to your foundation presently.

Response from Dr. Frascino


HIV cannot permeate across intact latex. If your West African sexual safari was truly "protected," your risk of HIV transmission is nonexistent (assuming the latex condom was used properly and did not fail).

So your risk is essentially nonexistent and your 13-week HIV-1 and HIV-2 ELISA tests are negative. I see no reason for additional or supplemental HIV tests. You are HIV negative. Congratulations! Now go celebrate (safely, of course).

Stay safe and you'll stay well (even in West Africa).

Dr. Bob

Oral Transmission?
Thank you for the response
