- DNA sequencing for Chlamydia trachomatis confirming presence of serovars L1, L2 or L3.
- Detection and confirmation of C. trachomatis (from any site) by detection of nucleic acid or antigen;
- Presence of one of the following:
-inguinal/femoral lymphadenopathy; OR
-suspicious lesion; OR
-sexual exposure to a partner with confirmed or probable LGV.
- Clinical symptoms consistent with LGV (i.e., proctitis, inguinal/femoral lymphadenopathy, or suspicious lesion) without a confirmed case of chlamydia; AND
- Sexual exposure to a partner with confirmed or probable LGV.
A case that meets the case definition for probable LGV with a negative test result for LGV serovars is not considered a probable LGV case. A case that meets the case definition for probable LGV with an inconclusive test result for LGV serovars on confirmatory (genotype) testing is considered a probable LGV case.
For more information on the case definition of lymphogranuloma venereum, please refer to the Technical Appendix of the annual STI surveillance reports.
