Overview
Natural History
- The incubation period for H. ducreyi is typically 4 to 10 days, after which erythematous papules arise.[1]
- Approximately 2 to 3 days after symptom onset, papules evolve into pustules.[2]
- Pustules may resolve spontaneously or ulcerate in approximately 1-2 weeks since formation. Patients typically develop between 1-4 ulcers.
- Inguinal lymphadenitis develops in approximately half of patients, usually unilaterally and more commonly in males than females, 1 to 2 weeks after appearance of primary ulcer.[3]
- In approximately 25% of patients with lymphadenitis, lymph nodes may swell to form fluctuant buboes. Untreated buboes may rupture, discharge exudate, and ulcerate.[3]
- Chancroid is not lethal.
Complications
- Coinfection with HIV:
- H. ducreyi facilitates infection of HIV
- Presence of HIV may result in atypical manifestations of chancroid including: increased number of lesions, extragenital lesions, delayed treatment response[1]
- Coinfection with syphilis
- Superinfection of lesions by other anaerobic bacteria such as Fusobacterium and Bacteriodes[4][5]
- Phimosis in men
