Bleeding gums are unlikely to be infected with HIV from kissing at this time. HIV is mainly transmitted through sexual contact, blood transmission and vertical transmission from mother to child. Although the mucous membrane of the mouth is broken when the gums bleed, it is very unlikely that a person with HIV will be infected with HIV because the level of HIV in the saliva of a person with HIV is low. If you suspect that you have a chance of contracting HIV, you can go to a regular hospital or the CDC after 3 months to have blood tests done to check for anti-HIV antibodies. If the test is negative, it is unlikely that you will be infected with HIV. If you are not sure, you can take another anti-HIV antibody test after 6 months, and if it is still negative, you can rule out HIV infection.
