Eating together does not lead to HIV transmission. Eating together with a person with HIV is a part of daily life contact and does not lead to HIV infection, so it is safe to have daily life contact with a person with HIV. There is no example of HIV transmission through saliva, so it is thought that such a small amount of contact with HIV will not lead to transmission. When we eat together, we will only come into contact with a small amount of saliva from a person with AIDS, so it will not lead to transmission. If your own oral mucosa comes in contact with blood, chest and abdominal fluids, reproductive tract secretions or breast milk of a person with AIDS, then there is a possibility of transmission. However, this will not happen when you eat together, and you will only come into contact with a small amount of saliva from a person with AIDS, so there is no need to worry about transmission.
