Chancroid is a sexually-transmitted infection (STI) associated with periodic outbreaks in the United States. The infection is more prevalent in some parts of Africa and the Caribbean. A type of bacteria called Haemophilus ducreyi is responsible for chancroid. The STI produces painful genital ulcers and tender, swollen lymph nodes. Chancroid is an STI that increases the risk of contracting human immunodeficiency virus (HIV), the virus that causes AIDS.
