For example, there are now several drugs to treat herpes, but none of them prevent it from coming back after treatment. There are now many drugs to treat HIV infection, and we are beginning to feel that we may be able to control this terrible disease. Finally, there is a great deal that we still don't know about the transmission of these diseases. Therefore, recommendations on how to avoid them can be difficult to give. I have received many questions about transmission of STDs through oral sex and kissing, and often cannot give a definite answer.
Epidemiologists talk often about the efficiency of transmission.
Most STDs are most efficiently transmitted through intercourse, but oral sex or even kissing may occasionally result in transmission. The answer is yes, warts are common on the fingers and may be so small that you don't know you have them. Warts can be transmitted to any skin surface or mucous membrane. Don't enter into sexual relationships indiscriminately. Always use condoms with new partners, and keep on using them until you know this is a long-term monogamous relationship.
