risk is very very low,

Detailed Answer:
HI, thanks for using healthcare magic

The risk of possible HIV transmission has been approximately calculated from pooling different medical studies.

The studies used different methods to the added approximate risk is only a guideline and it estimates the risk of transmission from a person who is positive.

In that case, the risk of transmission from a male to female, in a high income country is 0.08% (1: 1234) for each exposure. This means that 1 out of 1234 women who are sexually active with a male and exposed in each encounter may get the virus from a male with HIV.
(Can provide website with info to you)

Since your partner is not known to be positive, the risk should be lower. The precise risk is not known but it should be very very low.

If you wish to check your status, then you can.

I hope this helps, feel free to ask any other questions

Is not having any symptoms after the encounter and 6 years post a good determinate of low risk as well? I have a GP appt coming up and can get tested but I know that many say not to bother is single exposure and low risk.

Brief Answer:
risk is very low according to numbers mentioned

Detailed Answer:
HI

The fact that both of you are fine after 6 years is good and also reduces the risk.

There are a small group of persons who have minimal symptoms but most would have symptoms after a few years, a small number after 10.

As mentioned, risk after a single exposure is very low but if it is going to be at the back of your mind, the only definitive way to get an answer and relief would be to test.
