How much does a cut on your penis increase HIV transmission rates during unprotected anal sex?

I recently had penetrative anal sex with a stranger while on vacation in Barcelona, and it was unprotected. The next day, I noticed I had a small cut underneath the head (the more sensitive skin or inner foreskin) which is worrying me. At the time, I felt some discomfort which I attributed to friction or a lack of lube, but I now suspect I was feeling discomfort from the small cut. To make matters worse, I read that Barcelona has one of the highest HIV incidences in all of Europe, especially among MSM.

I also read that penetrative anal sex, unprotected, with an HIV positive partner is a 0.11% chance of infection if you are circumcised and 0.62% if you are uncircumcised, per encounter.

This leads me to three questions:
1. Roughly how do HIV transmission rates change/increase if you have small cuts or abrasions underneath the head of the penis (basically on the inner foreskin)?

2. If the receptive partner was recently infected (in the "window period" where their body is not yet producing antibodies to HIV), how much does the transmission rate increase? A friend had said it's 30x as high -- but that seemed like too high of an estimate (implying 3.3% if circumcised or 18.6% if uncircumcised)!

3. What is the best way to treat a cut on the sensitive skin beneath the penis head? Clearly a band-aid is not practical.

Combo test negative at 4 weeks

I had sex with a girl using a condom but i penetrated her first two time before using the condom. I caught chlamydia from this exposure but it is now treated. I had two red patch on the left side of my chest one weeks after. This lead to a skin rash all around my chest and back. I had few rash in the arms too. It's red and some are flat and others rashes looks like 5-10 pimples regrouped. Few days after, i had small fever for one or two night then it left. My rash was there for around 6-7 weeks.

I got tested with a combo test at 27 days (+6 hours) and i tested negative. My dermatologist made a biopsy punch and determined i had an allergic reaction.

I made another test at 11 weeks and I'm waiting for the results. I've been stressed a lot about this recently.

1. Do my symptoms look like ars from hiv?
2. Can my dermatologist could be wrong?
3. Can hiv skin rash stays that long (6-7 weeks)
4. If i already had the symptoms and i got tested 2 weeks after (at 4 weeks after exposure), is my test conclusive?

Thanks !!

HIV risks from oral sex and sharing sex toys

Hi! I had an encounter with another guy 2 weeks ago. I don't know his status but he claims to be HIV Negative. Our entire encounter lasted below 20 minutes. I had my penis sucked for about 3-5 minutes but I never sucked his. We shared this one sex toy, though. The one that looks like a vagina and simulates vaginal sex. We used antimicrobial soap as lubricant. He also suckled on my nipples. How much of a risk am I looking at here? I'm freaking out and I can't wait for three months to get tested. We have had encounters in the past and I tested negative after our encounters. Please get back as soon as you can. Thanks and more power to your site!

Follow-Up to Handling Items from Cashiers and HIV Risk

Thanks to Isla for pretty much clearing up the question I had, but I have just one more question, and I'm done. Suppose if you have the cuts that I mentioned in the previous message on your fingers and/or hands, perhaps some bleeding, and the cashier has cuts and bleeding on their fingers/hands, and your fingers/hands touch each other as they're handling your food and inanimate items and/or change? Can HIV transmission occur? I also have cracked skin on my fingers and hands as the weather has become drier and colder (they always crack and bleed during the Winter months). I hope this makes sense and all. Thank you in advance.

hiv transmission

I ask previous question but I give detail is not complete ..then my question is I work a hospital .I give the injection to the patient and after needle is a new not reuse but the syringe is same use just I same syringe use fill up of injection penta parazole fluid and pressure is increase in p.parazole bottle fluid is through my mouth &eye is only 1drop in mouth &eye.there is no blood present in syringe only infected by patient.patient hiv report is non reactive.so please tell me very fast can I risk of hiv?


How accurate is an RNA PCR HIV test at 11 days post exposure? I took the test 11 days post exposure (10/23/2015) and I will go in for the results on Tuesday. I wanted to know the exact accuracy of the test?

1) Is it 100% conclusive at this time and reliable at this time?
2) If the virus is not detected, does that mean I am not infected?
3) If the test doesn't detect the virus, should I retest at 4 weeks post exposure?
4) I told my doctor that if I am found negative, I want to go on PREP (Truvada). PREP + Condoms usage is the way to go, but how effective is PREP at preventing HIV in case the condom fails?
5) Has there been any documented case of HIV with people on PREP?
6) Should I also tell my doctor to prescribe me with Isentress? I heard it's good if combined with Truvada for PREP.

Thank you!

Mouth ulcer & Sandwich

Can mouth ulcers transmit Hiv, I have very big mouth ulcer, & was out with friends we shared a sandwich, like one had a bite, then I had a bite & last part was eaten by 3 friend, is there any chance of getting hiv if any of them is infected or can they get any infection from my mouth ulcers.

HIV? Repost ? Concern ?query ? Doubt

do know there are 4 situation which effects the hiv testing !
1) pep
2) treatment for hep c
3) treatment for cancer
4) immunodeficiency

I have take several duo test at
23rd day - Eclia
28th day - Eclia
42nd day - Eclia
58th day - Eclia
89th day - ELFA
93rd day - Eclia
103rd day - ELFA
103rd day - Cmia
122nd day - cmia

One hiv rna pcr 1 qualitative @ 103rd day - NOT DETECTED

One id NAT test @ 125th day - viral screening for hiv rna Dna 1/2 ! Hep c ! Hep b ! - NOT DETECTED

Two complete immunology test once th day when I had my IgM was slightly high and IgG was slightly low @ 48th day

Again took immunology test at 58th day
All were normal

Again took immunology test at 93rd day
All were normal

How do I know whether I have immunodeficiency ? I was serious kinda ill during my childhood
Suppose if I do I have some immunodeficiency
Does it affect my testing !?
Testing is delayed for antibodies ?

But even with some immunodeficiency antigens /rna/ dna / Id NAT should be detected?it detects the genetic material of hiv

I mean even if I do have some immunodeficiency
Test like I'd nat and pcr rna looks for virus only ?
Rather than looking for antibodies ?
