Chancroid Diseases: Symptoms, Causes, and Treatment

December 4, 2024

What are Chancroid Diseases?

Chancroid diseases refer to a type of sexually transmitted infection, primarily characterized by painful sores or ulcers in the genital area. The infection is caused by the bacterium Haemophilus ducreyi, and it is prevalent in tropical and developing regions. Chancroid is often confused with similar infections like syphilis and genital herpes due to overlapping symptoms.

Symptoms and Diagnosis

The most noticeable symptom of chancroid diseases is the appearance of one or more painful genital ulcers. These lesions can be very tender and may also ooze pus. Other symptoms can include swollen lymph nodes in the groin and discomfort during urination. Due to the severity of the symptoms, it is important to seek medical attention for a definitive diagnosis. A healthcare provider can usually diagnose it through physical examinations and tests.

Treatment Options

Fortunately, chancroid diseases are treatable with antibiotics. Medications such as azithromycin or ceftriaxone are common choices for effective treatment. It is crucial to complete the prescribed course to ensure that the infection is entirely cleared. Additionally, individuals diagnosed with chancroid should inform their sexual partners, who may also require treatment to prevent reinfection or further spread.



Chancroid is a bacterial infection caused by Haemophilus ducreyi. It is a sexually transmitted infection (STI) that affects the genitals and is characterized by painful ulcers and swelling.

Causes and Risk Factors:

  1. Sexual contact: Chancroid is primarily spread through sexual contact with an infected person.
  2. Skin-to-skin contact: Chancroid can also be spread through skin-to-skin contact with an infected person.
  3. Contaminated objects: Chancroid can be spread through contact with contaminated objects, such as towels or bedding.

Symptoms of Chancroid:

  1. Painful ulcers: One or more painful ulcers on the genitals, typically on the penis or vulva.
  2. Swollen lymph nodes: Swollen and painful lymph nodes in the groin area.
  3. Foul odor: A foul or unpleasant odor from the ulcers.
  4. Painful urination: Pain or discomfort while urinating.
  5. Fever: Elevated body temperature.

Complications of Chancroid:

  1. Scarring: Chancroid ulcers can leave scars on the genitals.
  2. Abscesses: Chancroid can cause abscesses, which are painful collections of pus.
  3. Fistulas: Chancroid can cause fistulas, which are abnormal connections between the skin and internal organs.
  4. Phimosis: Chancroid can cause phimosis, which is a tightening of the foreskin that can make it difficult to retract.

Diagnosis of Chancroid:

  1. Physical examination: A healthcare provider can diagnose chancroid based on a physical examination of the genitals.
  2. Laboratory tests: Laboratory tests, such as a Gram stain or culture, can confirm the diagnosis.

Treatment of Chancroid:

  1. Antibiotics: Chancroid is typically treated with antibiotics, such as azithromycin or ceftriaxone.
  2. Pain management: Pain management medications, such as acetaminophen or ibuprofen, can help manage pain and discomfort.

Prevention of Chancroid:

  1. Safe sex practices: Practicing safe sex, such as using condoms, can reduce the risk of transmission.
  2. Avoiding sharing personal items: Avoiding sharing personal items, such as towels or bedding, can reduce the risk of transmission.
  3. Getting tested regularly: Getting tested regularly for STIs, including chancroid, can help detect and treat infections early.
