Mosquitoes mainly transmit malaria, dengue fever, yellow fever, etc., but not AIDS. The main ways of HIV transmission are blood transmission, sexual transmission and mother-to-child transmission. 1. Blood transmission: When a normal person has a wound on the skin and comes into contact with something containing the blood of a person with AIDS, the AIDS virus will enter the body through the wound and cause infection, and it is also possible to be infected by sharing a syringe. 2. Sexual transmission: When you have sex with someone with AIDS, you don’t take protective measures, which can easily lead to infection. 3. Mother-to-child transmission: Mothers with AIDS transmit the virus to their babies through the placenta, the birth canal or through breastfeeding. AIDS often manifests itself in fever, sore throat, nausea, rash, swollen lymph nodes and neurological symptoms. If the above symptoms occur, especially after high-risk behaviors, it is recommended to go to a regular hospital to find a professional doctor for examination in order to clarify the diagnosis, and if diagnosed, must be standardized treatment under the guidance of the physician.
