One year after high-risk behavior is negative, and if there is no other high-risk behavior, it usually does not turn positive. Two to six weeks after high-risk behavior, you can go to the hospital for HIV antibody test, if it is negative, and after three months and retest is still negative, generally can rule out the possibility of AIDS; if there is no other high-risk behavior, generally will not turn positive. Under the premise of excluding AIDS infection, if there are uncomfortable symptoms, we need to consider the possibility of other diseases. If the test is negative after one year of high-risk behavior, HIV infection can be ruled out. If there are symptoms, it is recommended to go to the hospital to consult a specialist, and if necessary, consult a psychologist.
