Chancroid is a sexually transmitted infection (STI) caused by the
Haemophilus ducreyi bacterium. It causes painful open
sores (ulcers) in the genital area and swelling of the lymph nodes in the
Chancroid is not common in the United States but is more common in
patients who also have human immunodeficiency virus (HIV) infection. Some
people who have chancroid are also infected with syphilis or genital herpes
Without proper treatment, ulcers require longer periods to heal,
which increases the likelihood of getting or transmitting HIV infection.
Successful treatment with antibiotics cures the chancroid
infection, relieves symptoms, and prevents transmission to others. In extensive
cases, scarring can occur despite successful treatment.
