What Are The Chances Of HIV Infection After A Sexual Encounter?

default
Posted on Thu, 8 Jan 2015
Question: i recently had an experimental sexual encounter with a sex worker in which a dildo was used in my anus. i don't recall if they used a condom over the dildo. the dildo was dry and i am almost certain probably had not been used in the hours prior to my arrival. my question is if the dido had been used on someone else the day prior or for that matter even a few hours earlier who was hiv positive and the sex worker did not properly clean the dildlo could i still get hiv in the car that the dildo had been exposed to air and was dry ? The dildo was a hard plastic and looked clean FYI. thanks

Brief Answer:
Chances are slim to non-existent

Detailed Answer:
Hello sir and welcome.

Thank you for writing to us.

I have gone through your query with diligence and would like you to know that I am here to help. The topic is about 'how long HIV can survive outside the body?'. This topic has been debated for ages now, and so many studies have taken place on finding the result.

Recent studies have proved that the HIV virus cannot survive outside the body for more than a few minutes. So, even if the previous person who the dildo was used on did have HIV (which is a less likely possibility), the virus could have only survived on the dildo for a few minutes from the bodily fluids of that supposedly HIV-infected individual.

So I do not think your concerns are warranted and the chances of your being HIV-infected is very very unlikely. I hope you find my response helpful sir. Please feel free to write back to me for any further clarifications, I would be more than happy to help you.

Best wishes.

Thank you. Very helpful indeed. Finall question. Is the transfer in that case even possible if there was say bodily fluids on the sextoy and they were shared let's say from one anus to the other with in that few minutes in a hypothetical scenario with a dildo? Or does it prettying almost only transfer from inter course ?

In other words can a dildo even transfer the virus considering there would be a swap that goes through the air to transfer.

Brief Answer:
I have put forward a few scenarios for you sir

Detailed Answer:
Hello once again.

The dildo can transfer the infection only if at all bodily fluids are involved, the scenarios are the following:

+If the first individual on whom the dildo was used was indeed infected and then the dildo was used on the second individual almost immediately or within 30 minutes, and the second individual had some wound in the anal region or within with which the bodily fluids of the first person from the dildo came in contact with

+If the first individual on whom the dildo was used was indeed infected and then the dildo was used on the second individual almost immediately or within 30 minutes, in regions other than the anus and that particular region had a wound through which the virus could have entered.

Other than this, there is no chance for transmission of infection. Even with the above 2 scenarios, chances of transmission are very very low. So, in my opinion chances of transmission itself are very slim to non-existent.

I hope this response helps you sir. Please feel free to write back to me for any further clarifications, I would be more than happy to help you.

Best wishes.
