Blood draws in hospitals are not infected with HIV because the medical equipment used in hospitals for blood draws are all disposable. All blood collection devices and tubes are used exclusively by the patient, and are disposed of in the medical waste after use. There is no need to worry about repeated use, so there is no possibility of HIV infection. In fact, there are three main ways of HIV transmission: sexual transmission, blood transmission and mother-to-child transmission. Therefore, if you take precautions in these three areas, you can avoid contracting AIDS. Common contact with AIDS patients in daily life, such as living together, studying, using the toilet, eating, showering, etc., will not transmit AIDS.
