HIV from Deep Kissing? Possibly Blood-Related

The CDC reports a case of
apparent HIV transmission by deep kissing, but suggests that the
transmission was due to oral mucous membrane exposure to blood rather than via saliva.

The couple involved was part of an ongoing study of couples in which
one partner has HIV. Interviewers questioned the partners separately
about their sexual practices over a one-year period. Both reported
consistent use of male latex condoms, no intercourse during menses, no
anal penetration, and no condom breakage during the study period.
Occasional oral sex did not involve exchange of blood or semen. They engaged in open-mouth deep kissing several times monthly.

The HIV-positive male partner reported that his gums bled frequently
after brushing and flossing, and the woman had had endodontic therapy.
The woman had an illness consistent with acute retroviral syndrome
during the study period; the CDC postulates that this was when she
acquired the infection. DNA sequencing and phylogenic analysis suggest that her HIV strain was acquired from her partner.

Comment: Although the CDC concluded that exposure of oral
mucous membranes to blood during deep kissing was the most likely mode
of transmission in this case, an editorial note remarks on the
"multiple routes by which exposure to infectious body fluids can occur
among sexually intimate persons." Clinicians and educators should be aware that, although rare, it appears possible to transmit HIV orally.
