Question: What are chances of a guy contracting HIV from a HIV infected lady after 1 unprotected sexual intercourse with her
Answer: You can get infected from a single sexual encounter with someone with HIV 

Although I cannot give you exact figures as regards your actual chances or probability but I know that the chances vary significantly based on other factors such as kind of sex if you are a man or woman the viral load of the person with HIV etc 

The risk is higher in people with other STIs or if the infected person has a high viral load People with HIV who are compliant with their medications ARVs can have really low viral load that they cannot infect other people most times Multiple sexual exposures increase the chances of infection Anal sex has significantly higher risk of infection up to 20 times more than vaginal sex and women are at a higher risk than men

Finally if you are worried about exposure please speak to your doctor about getting on post exposure prophylaxis
