    Causes, incidence, and risk factors

    Lymphogranuloma venereum (LGV) is a chronic (long-term) infection of the lymphatic system caused by three different types of the bacteria Chlamydia trachomatis. The bacteria spread through sexual contact. The infection is caused by a different bacteria than that which causes genital chlamydia.

    LGV is more common in Central and South America than in North America. Every year, a few hundred cases of LGV are diagnosed in the United States. However, the actual number of infections is unknown.

    LGV is more common in men than women. The main risk factor is having multiple sexual partners.
