Lymphogranuloma Venereum (LGV)
(caused by 3 subtypes of Chlamydia trachomatis, a bacteria)
NOTE: LGV is rare in the U.S. If you have signs or symptoms of any sexually transmitted disease you should see a health care provider for evaluation and possible treatment. Suspect cases of LGV should be coordinated by the MDH Public Health Laboratory to facilitate submission of diagnostic specimens. Please contact (651) 201-5257 for further information.
Lymphogranuloma venereum (LGV) is a sexually transmitted disease (STD) caused by a type of chlamydia trachomatis (serovars L1, L2, or L3) that rarely occurs in the United States and other industrialized countries. However, recent outbreaks of LGV have been reported among men who have sex with men (MSM) in Europe and other U.S. cities. If you have signs or symptoms of any sexually transmitted disease you should see a health care provider for evaluation and possible treatment.

Signs and Symptoms
Early stage LGV symptoms:
- Begin 3–12 days or longer after exposure
- Early symptoms often go unnoticed or never occur
- Soft red, painless sore or lesion that forms on or near the genitals or anus
- Sores can also occur in the throat or mouth from oral sex
- The sore heals rapidly in a few days
Later stage LGV symptoms:
- Begin 2–6 weeks or longer after primary lesion
- Swollen lymph glands on one or both sides of the groin
- Pain during urination or when passing stools
- Rectal bleeding
- Pain in lower abdomen or back
- Pus-filled or bloody diarrhea

LGV is spread by:
- Vaginal sex
- Oral sex
- Anal sex
If left untreated, LGV can:
- Spread to sex partners.
- Cause severe scarring and deformed genitals.
- Cause scarring of rectum causing narrowing.
- In women, create an opening between the vagina and anus (fistula).
- Cause brain inflammation (very rare).
- Avoiding vaginal, oral or anal sex is the best way to prevent STDs.
- Latex condoms, when used consistently and correctly, can reduce the risk of transmission of LGV.
- Always use latex condoms during vaginal and anal sex.
- Use a latex condom for oral sex on a penis.
- Use a latex barrier (dental dam or condom cut in half) for oral sex on a vagina or anus.
- Limit the number of sex partners.
- Notify sex partners immediately if infected.
- Make sure partners are tested and treated.
Testing and Treatment
- Get a test from a medical provider if infection is suspected.
- LGV can be cured using medication prescribed by medical provider.
- Partners should be treated at same time.
