Beyond the diagnosis of overt
AIDS, the important information is whether she is on anti-
HIV drugs; and how much
HIV is in her blood, i.e. the result of a viral load test. If she is being treated and has an undetectable or very low viral load, there would be little or no risk even with unprotected intercourse. If you do it, you probably would not be infected. But common sense says there is no point in taking the chance.
