Sharing a washing machine with a person with AIDS will not lead to HIV transmission. Even if there is blood or other bodily fluids containing large amounts of HIV in the washing machine, the washing machine will not contain large amounts of HIV on the clothes as long as the clothes are cleaned, so it will not cause transmission. Daily contact with a person with AIDS does not cause transmission because it is unlikely that daily contact will result in exposure to body fluids containing large amounts of HIV. These fluids are mainly blood, reproductive tract secretions, breast milk, chest and abdominal fluids, cerebrospinal fluid, etc. The body fluids that can be contacted in daily life are generally sweat, respiratory droplets, saliva, urine, etc. Although these body fluids contain a small amount of HIV, it has been found through corresponding research that even if a small amount of HIV comes into contact with the broken skin or mucous membrane of a normal person, it will not cause infection, most likely because the amount of HIV contained in it is too small.
