Chancroid: Symptoms, Diagnosis & Treatment

What Is Chancroid?

Chancroid is a bacterial sexually transmitted infection (STI) that results in painful genital ulcers and swollen lymph nodes near the groin.

The condition arises from Haemophilus ducreyi, a bacterium transmitted through direct sexual contact. Although now rare in countries with established STI control programmes, chancroid continues to occur in parts of Africa, the Caribbean, and Southeast Asia where access to healthcare or preventive measures may be limited.

The open sores caused by chancroid not only lead to significant discomfort but also increase susceptibility to other infections, including HIV. Without proper management, the sores may deepen, leaving scars or causing lasting damage to surrounding tissue.

What Are the Causes and Risk Factors for Chancroid?

Chancroid occurs when Haemophilus ducreyi bacteria penetrate small breaks or abrasions in the skin that may form during sexual contact. Transmission happens through direct exposure to an infected person's sores during vaginal, oral, or anal sex.

Risk of infection rises with certain behaviours or exposures, such as:

• Having unprotected sex with one or more partners
• Engaging in sexual activity with individuals from regions where chancroid remains prevalent

The infection does not spread via casual interactions, shared utensils, or toilet facilities.

How Is Chancroid Infection Treated and Managed?

Chancroid is usually treated with antibiotic therapy that targets Haemophilus ducreyi, relieves discomfort, and supports ulcer healing. Noticeable improvement often occurs within 1 to 2 weeks after starting treatment.

Common antibiotic options include azithromycin, ceftriaxone, ciprofloxacin, and erythromycin. These medicines shorten the infection's duration and prevent further transmission.

When lymph nodes become significantly swollen or develop abscesses, minor drainage or aspiration may be needed to relieve pain and promote recovery. It is also important to avoid sexual contact until all ulcers have completely healed to prevent reinfection and protect partners from exposure.

What Is the Cost of Chancroid Testing and Treatment?

At Singapore Women's Clinic, we provide private and confidential STI screening, including targeted testing for chancroid. Confirming the diagnosis allows appropriate antibiotic treatment to begin promptly if infection is detected.

Both male and female doctors are available at our clinics, depending on appointment availability, to ensure your comfort.

For enquiries about testing options or to schedule a consultation, please contact us directly.

How Can Chancroid Infection Be Prevented?

Chancroid prevention relies on safer sexual practices and early STI screening. Important steps include:

• Using condoms correctly during all sexual encounters
• Reducing the number of sexual partners
• Avoiding sex with individuals who have visible genital ulcers or unexplained sores
• Seeking prompt assessment if ulcers, pain, or unusual discharge develop
• Going for regular sexual health check-ups helps detect infections early and reduces the risk of complications or onward transmission.
