Although this usually means sexual intercourse, it also includes close body contact, kissing, cunnilingus, anilingus, fellatio, mouth–breast contact, and anal intercourse. Many STDs can also be transmitted to the fetus in utero by transplacental spread or passage through the birth canal and via lactation during the neonatal period. The organisms involved are adapted to growth in the genital tract and are present in body secretions or blood. Having one STD increases the risk of coinfection with other STDs; therefore, full screening should be offered to all patients with a new STD diagnosis.
