The elimination of Plasmodium falciparum and P vivax does not mean the end of malaria in South-East Asia. Hundreds of cases of non-human primate malaria are diagnosed each year in some countries, caused mainly by Plasmodium knowlesi but also others such as P cynomolgi, P inui, P coatneyi and others. These infections cloud the issue of countries being registered by WHO as having reached malaria elimination, and pose a risk of sustained and pernicious malaria infection.
