Transmission routes of AIDS
Disease description:
Recently, I heard that a male colleague at the company tested positive for HIV infection. He is only 28 years old. HIV/AIDS usually seems far away from us, so I never expected that a colleague nearby could actually be infected. May I ask, what are the transmission routes of HIV/AIDS?

AIDS (Acquired Immune Deficiency Syndrome) is primarily transmitted through the following routes:
1. Blood transmission: This is the most common mode of transmission, including the use of unsterilized syringes and needles, transfusion of HIV-contaminated blood or blood products, and sharing personal hygiene items such as razors and toothbrushes.
2. Sexual transmission: Unprotected sexual activity, whether between individuals of the same or opposite sex, can potentially transmit the HIV virus. Using condoms can significantly reduce the risk of infection.
3. Mother-to-child transmission: Pregnant women infected with HIV may pass the virus to their infants during pregnancy, childbirth, or breastfeeding. The risk of mother-to-child transmission has been significantly reduced through effective antiviral treatment.
4. Body fluid exchange: Although HIV exists in certain bodily fluids such as saliva, sweat, and tears, the viral load in these fluids is generally extremely low and insufficient to cause transmission, unless there is an open wound or direct entry into the bloodstream.
HIV is not transmitted through everyday contact such as handshakes, hugs, coughing, sneezing, sharing utensils or bathrooms. If you have any concerns, it is recommended to seek medical advice promptly.
