Hi there,
Thank you for choosing AIDS Vancouver for your source of HIV/AIDS related information. It's great to see that you are taking initiative when it comes to your health and well being!
Unprotected sex is considered a high risk activity for HIV transmission; HIV can be transmitted from one single encounter. However, it's important to keep in mind that engaging in unprotected sexual activity with an individual who is HIV positive does not guarantee that HIV will be transmitted. I have attached a chart that I think will clear up any confusion about HIV transmission:






·         blood (including menstrual blood)
·         semen
·         pre-cum
·         rectal secretions
·         vaginal fluids
·         breast milk


·         unprotected anal or vaginal intercourse
·         sharing needles
·         mother to child


·         vagina
·         anus
·         urethra in the penis
·         open cuts and sores (in theory)
·         other mucosal membranes
·         points of needle injection







From the chart, you can see that the high risk activities for HIV transmission are: unprotected anal/vaginal sex and sharing needles. With this in mind, you can take comfort in the fact that you are in control of your HIV status. Keeping the lines of communication open with your partner(s), practicing safe sex, testing regularly for sexually transmitted infections (STIs) and HIV, as well as steering clear from needle sharing are all great ways to keep your risk of transmission extremely low. 
According to the World Health Organization (WHO) all HIV testing is conclusive 12 weeks (or 84 days) post exposure, provided there have been no other exposures during that window period. Up to 95% of cases can be detected through testing within 4-6 weeks of the exposure. From the information you have provided, I would encourage you to do the following:
1.) Get tested for HIV at the 6 week mark. If you receive a negative result at this point, this is an excellent indication that you are indeed HIV negative. 
2.) Get tested for HIV again at the 12 week mark. If you receive a negative result, then you are definitely HIV negative, and do not require further testing. 
At AIDS Vancouver we encourage all sexually active individuals to get tested for all sexually transmitted infections (STIs), including HIV, as part of their health routine. This can be in the form of testing every 3 months, bi-annually, annually or whatever suits your lifestyle. 
I hope I have answered your questions, and if you have any other concerns please do not hesitate to contact us!
All the best,
