Chancroid : Patient Information and Testing Services

Recognizing the Symptoms of Chancroid

Symptoms typically begin 4 to 10 days after sexual exposure. Patients usually develop a small, red pustule on the genitals that breaks down within a day or two to form a painful, soft ulcer with irregular borders.

Key symptoms include:

• Painful ulcers on the genital area.

• Swollen lymph nodes in the groin, which may form large, draining abscesses (buboes).

• Additional symptoms in some cases:

  • Rectal bleeding.

  • Pain with bowel movements.

  • Vaginal discharge.

  • Painful urination and sexual intercourse in women.

Is Chancroid Associated with Other Genital Ulcer Diseases?

Chancroid is one of the causes of genital ulcer diseases, along with Herpes Simplex Virus (HSV) Type 2, Syphilis, and Lymphogranuloma Venereum (LGV). While there is no direct association, any form of STD can increase the risk of contracting another, including chancroid.

Genital ulcer diseases are particularly concerning as they greatly increase the risk of HIV transmission. According to the World Health Organization (WHO), the presence of genital ulcers can increase HIV transmission risk by 10%-50% in women and 50%-300% in men.

How Do You Test for Chancroid?

Currently, there is no laboratory test that can immediately confirm the diagnosis of chancroid. Haemophilus ducreyi can be isolated on a special culture media, but this is not readily available in many centers and has a sensitivity of less than 80%.

Diagnosis is made based on clinical judgment. According to the US Centers for Disease Control and Prevention (CDC), a probable diagnosis can be made if:

• There is the presence of one or more painful genital ulcers.

• The ulcers and, if present, enlarged groin lymph nodes are typical for chancroid.

• Tests for syphilis and herpes simplex virus (HSV) are negative.

Treatment for Chancroid

Appropriate treatment of chancroid cures the infection, reduces complications, and prevents transmission. Treatment should begin as soon as chancroid is suspected due to the lack of fast and accurate laboratory testing.

Key aspects of treatment include:

• Antibiotics: These cure the infection and help reduce scarring as the ulcer heals. Your doctor will prescribe the appropriate antibiotic based on your condition.

• Bubo Management: If buboes are present, they should be drained using needle aspiration or surgery to reduce swelling and pain.

• Partner Notification: Sexual partners should be informed, examined, and treated regardless of symptoms if they had contact within 10 days preceding symptom onset.

Why Early Treatment Matters

Chancroid can increase the risk of other infections, including HIV, if left untreated. Early intervention ensures effective treatment and prevents further complications.
