Saliva does not generally transmit HIV. This is because the amount of HIV in saliva is very small, but saliva can contain HIV, but only in very low concentrations. According to the 17th edition of Nielsen Pediatrics, the amount of HIV-infected particles in 1 ml of saliva is less than 1. So with such a low amount it is likely that you will not be exposed to any HIV when you touch saliva. So theoretically, the possibility of transmitting HIV would be very low. However, in practice, there are no examples of HIV transmission through saliva. Therefore, it is currently believed that HIV cannot be transmitted through saliva. Therefore, daily contact with a person with AIDS will not lead to the transmission of AIDS. A common meal or even a ritual kiss with a person with AIDS will not lead to HIV transmission. However, if the kiss is deep, the bodily fluids in contact may not only be saliva, but also blood from bleeding gums of AIDS patients.
