Chancroid is a sexually transmitted infection (STI) caused by the bacteria Haemophilus ducreyi. It typically presents as painful genital ulcers, which is the key difference from syphilis (chancre), where ulcers are usually painless. If left untreated, chancroid can lead to complications and increase the risk of passing the infection to others.

Causes & Risk Factors of Chancroid

• Caused by the bacterium Haemophilus ducreyi
• Unprotected sexual activity, especially penetration
• Multiple sexual partners or frequent partner changes

Symptoms of Chancroid

Symptoms often appear within 3-7 days after infection:

• Painful genital ulcers with irregular edges
• Ulcers may appear in several spots, often moist with discharge
• Swollen, tender lymph nodes in the groin
• In women: possible vaginal discharge, pain during sex, or painful urination

Diagnosis of Chancroid

A doctor will check your symptoms, examine the ulcers, and take your sexual history. For confirmation, tests such as swab culture or PCR may be used to distinguish chancroid from syphilis or herpes.

Treatment of Chancroid

• Antibiotics (Azithromycin, Ceftriaxone, or Ciprofloxacin) as prescribed
• Proper wound care and hygiene
• Avoid sexual activity until fully healed
• Partner testing and treatment to prevent reinfection

Prevention

• Always use condoms
• Get regular sexual health checkups
• Check your partner for unusual lesions before intimacy
• See a doctor immediately if you notice unusual ulcers
