What are the main causes of Chancroid?

  • Chancroid is a sexually transmitted infection (STI) caused by the fastidious gram-negative bacterium known as Haemophilus ducreyi.
  • The infection is transmitted primarily through sexual contact, including vaginal, anal, or oral sex, with an infected individual who has open sores.
  • Transmission is more common in areas with limited healthcare resources and is often associated with commercial sex work and illicit drug use.

Key symptoms of Chancroid to watch for

  • The hallmark symptom is the appearance of one or more small, soft, and extremely painful genital ulcers with ragged, undermined edges.
  • In about half of the cases, individuals develop tender, swollen lymph nodes in the groin area, which can rupture and form abscesses.
  • Unlike syphilis sores which are typically painless, chancroid ulcers are very tender and bleed easily upon contact, aiding in a differential diagnosis.

How can you prevent Chancroid effectively?

  • Consistent and correct use of latex or polyurethane condoms during all sexual encounters is the most effective way to reduce transmission risk.
  • Abstaining from sexual activity or being in a long-term, mutually monogamous relationship with a tested, uninfected partner can prevent infection.
  • Practicing good personal hygiene and seeking regular STI screenings, especially if you have multiple partners, is crucial for early detection and prevention.
