The probability of contagion is very low, even if the person living with HIV has touched the doorknob, if it takes more than an hour, the AIDS cells are close to necrosis and collapse, and it is difficult to move to a new living body. So rest assured. Then sweat is not very contagious. You won't be infected.

There must be three conditions for HIV infection at the same time:

1. There must be a source of infection, only sex or sharing needles itself can not produce HIV, and there must be enough virus to become infected, AIDS patients have high HIV in their blood, semen, vaginal secretions, milk, and wound exudate, so the risk of contact with these body fluids is high, and HIV in saliva, tears, and urine is soft, and the possibility of infection is very low, and sweat, vomit does not contain HIV, and gastric juice, Intestinal fluid has a killing effect on HIV, and it is not possible to transmit AIDS through daily contact.

2. There must be the participation of people living with HIV, and there must be sufficient conditions for HIV infection, sexual intercourse, blood, blood products and unsterilized syringes are all ways of AIDS transmission. HIV in the mother's body can be transmitted to the child during pregnancy, childbirth, and breastfeeding.

3. AIDS can be transmitted through the vagina, rectal mucosa or tiny tears in the mouth, mouth ulcers or tears in the skin, and bloody needles can be infected with HIV.
