HIV is transmitted from male to female and from female to male.

AIDS male-to-female and female-to-male probability is not the same, usually male-to-female probability is greater than female-to-male, but also need to consider whether to use condoms in the same room; because AIDS incubation period is long, there are no obvious symptoms in the early stage, if you worry about AIDS, you should go to the hospital's STD department in time for examination.
