Daily life is contacted will not infect AIDS
The HIV-positive though appearance is the same as normal people, but blood, seminal fluid, vaginal secretion, the intersection of skin and mucomembranous damage or inflammatory ulcer of them ooze out on liquid containing a large amount of HIV, have very strong infection; The milk includes the virus too, infective. Can find the virus in the saliva, tear, sweat liquid and urine, but include little virus, it is not big to be infective. There are three AIDS already verified infects routes:

1,Spread through sex intercourse
Transmit the main infection route that is HIV through two sexual behaviors: No matter homosexuality or anus between the two sexes hand in and mouth hand in have great infection dangerous.
Sex contagion among the same sex
In the AIDS patient of the male adult, homosexuality person's large percentage, especially in some countries and regions in U.S.A., Europe, with homosexual spreading, is infected with HIV or suffers from the number of people of AIDS to increase constantly, this kind of sexual behavior has already become the main way to transmit AIDS. Been infected with the man of HIV, a large amount of HIV exists in its son of seminal fluid, the density can be up to 107-8 ml liquid. In addition, the rectum of male rectum is different from dissection institutional framework of women's vagina, the vagina, in order to reply the skin on one floor of scales, and the rectum mucous membrane is the skin on the column, relatively women's vagina is fragile for its resistance, and then flexible but lower than the vagina too. So, they are in the course of handing in the anus, extremely apt to make the thin and fragile mucomembranous surface of rectum rectum damage, form the wound surface. HIV in the seminal fluid enters the blood circulatory system through the slight wound surface of rectum while ejaculating, make the organism infected with AIDS. In addition, organization person who dissolve antigen wait for cell pass into through damaged the intersection of rectum and mucous membrane, the receptor can be implanted and resisted the constellation primary response, or the host resists and implants reacting. This two can all cause serious immune inhibition. Homosexualities male is often been for unitarity partner, they and a lot of have frequent sex contact partner piece, so, the already sexual persons who have taken the initiative passed HIV to the passive one through the seminal fluid, it is passive also have there is other people's seminal fluid with HIV in the body, and the passing the virus to persons who take the initiative. Spread chance of this bigger HIV.
