To accurately assess the burden of simian malaria in humans imported to the United States, molecular testing on all malaria specimens from Asia and non-falciparum specimens from South America is needed. The currently approved RDT detects 2 different malaria antigens; one is specific for P. falciparum and the other is found in all 4 human species of malaria. Indirect fluorescent antibody (IFA) test. 1. The use of the RDT does not eliminate the need for malaria microscopy. It was thought that natural infections of simian malaria in humans were rare and not of public health importance until recent reports from Asia have suggested that P. knowlesi, a simian malaria species, is emerging as a public health problem.
