    How to prevent chancroid transmission?


    • In the presence of an ulcer, lump, bump or unusual redness it is important to refrain from all sexual activity (abstinence) and to consult a physician;
    • By contacting and advising all sexual partners of the last 90 days prior to symptom onset and/or diagnosis. Partner notification is extremely important for the chain of transmission to be interrupted. Partner notification also ensures that you are not re-infected by one of your sexual partners.
    • By discussing issues of sexual health with all sexual partners. Ask current or new sexual partner(s) about their previous sexually transmitted infections history — Have they ever done screening test?;
    • The systematic use of a condom ensures a good measure of prevention with respect to all sexually transmitted illnesses, including chancroid. The condom must be used appropriately and must not be expired (check the date).
