Sexual transmission refers to the spread of infections or diseases through sexual contact between individuals. This can include the transmission of sexually transmitted infections (STIs) such as HIV, gonorrhea, syphilis, chlamydia, and herpes. Sexual transmission is a major route of transmission for many infectious diseases and effective prevention strategies, such as the use of condoms and regular testing, are essential in reducing the spread of these infections. Researchers study sexual transmission to understand the mechanisms of how infections are spread through sexual contact and to develop effective prevention and intervention strategies.
