Mystery of blackwater fever from an Australian perspective.

Blackwater fever is a haemolytic syndrome associated with malaria that coincided with the use of quinine chemoprophylaxis. Once quinine was no longer chronically used to prevent malaria, blackwater fever largely disappeared and its aetiology remains poorly understood. Blackwater fever is representative of classical tropical medicine and its history was reflected in Australia's colonial development of Papua New Guinea particularly as reported in the Australian medical literature.
