Malaria in southeast Queensland in 1979.

The incidence of malaria in Australia is increasing. With the emergence of strains of Plasmodium falciparum resistant to chloroquine there are new lessons to be learned by laboratory workers in the species diagnosis; by clinicians in the clinical manifestations, the treatment of prophylaxis; and by members of the public about the dangers of malaria, and how it can be prevented. At the same time, old knowledge must not be forgotten. This paper reports some recent experience with a sizeable number of cases.
