Kissing Animals

Disease transmission
Diseases which may be transmitted through kissing include mononucleosis, allergic reactions to nuts and drugs, and herpes, when the infectious virus is present in saliva. Research indicates that contraction of HIV via kissing is extremely unlikely, although a woman has been infected with HIV by kissing (in 1997). Both the woman and infected man had gum disease, so transmission was through the man's blood, not through saliva.
