Imported malaria notified in New South Wales and the Australian Capital Territory, including trends in notifications of Plasmodium falciparum, 1989 to 2003

Abstract

Malaria is the most common tropical parasitic infection imported into NSW. This article presents a review of all cases of malaria diagnosed and notified in NSW and the Australian Capital Territory from 1989 to the end of 2003. Of the four species of malaria infecting humans, Plasmodium falciparum, P. vivax, P. ovale and P. malariae, P. falciparum is most likely to be associated with serious illness and death. Therefore, trends in the occurrence of this species over the period are examined. This information is of value to clinicians and public health professionals in highlighting both the importance of rapid and accurate diagnosis of malaria and the changing trends in the origin of imported cases.
