Public Health Significance and Occurrence

  • Donovanosis is a rare cause of genital ulceration but should be considered in patients returning from areas where the disease may be endemic e.g. PNG, Southern Africa, India and parts of South America.
  • It is primarily sexually transmissible but may be transmitted vertically and by casual contact.
  • Incident cases were found as recently as mid-late 2000s in northern and tropical Australia among Aboriginal and Torres Strait Islander people, but it is now very rare in these areas.
  • The last notified case of Donovanosis in Queensland was in 2010.

It may occur in children aged 1-4 years but the prevalence is highest in adults aged 20-40 years. The male:female ratio is 2.5:1. Affected individuals are usually sexually active. The disease appears to be poorly communicable. It can be confused or coexist with other causes of ano-genital ulceration.

The sequelae of the ulcerative/destructive process associated with this infection can result in stenosis, fistula formation, lymphatic obstruction and secondary infection, all of which can cause considerable morbidity. There is an association between donovanosis and HIV infection, particularly in men with genital ulcers of long duration. Treatment relapses are common and may occur up to 2 years after apparently successful treatment.
