Discussion about Contagion of Chlamydia:

Chlamydia: NWHIC (Excerpt)

Like other sexually transmitted diseases (STDs), chlamydia is spread during sexual intercourse via the exchange of bodily fluids through mucous membranes in the anus, mouth, and genital areas. Because there are often no symptoms for chlamydial infection, people who are infected may unknowingly pass the bacteria to their sexual partners. (Source: excerpt from Chlamydia: NWHIC)

Lesbian-Health: NWHIC_1 (Excerpt)

There is no evidence at this time that gonorrhea, syphilis, or chlamydia is sexually transmitted between women who are sexually active with women, but large studies have not been done. The majority of lesbian women are sexually exclusive with women (although 90% have been heterosexually active at some time): however, there are some lesbians who do have male partners, and this subpopulation of lesbians are at risk for gonorrhea, chlamydia and syphilis. (Source: excerpt from Lesbian-Health: NWHIC_1)
