Sharing towels and toilets does not lead to HIV transmission. The HIV virus is not viable in the air, but only in the human body, and once it is removed from the body, it will quickly lose its activity. Therefore, among the main modes of HIV transmission, there is no transmission through towels or toilets. There are no clinical cases of HIV transmission. For the HIV virus, the common disinfectants currently available in the market can play a relatively clear role in killing it. Therefore, there is no need to worry about sharing toilets and towels, which may lead to transmission.
