**4.1 Suppressive treatment**

The symptoms of malaria are relieved by suppressing the erythrocytic stage of the parasitic development in the suppressive treatment. This involves the administration of appropriate blood schizonticidal agents. In all cases of non-falciparum malaria (*P. vivax*, *P. ovale*, P. malariae and *P. knowlesi*), it consists of the administration of chloroquine. Also, presumptive treatment for malaria involves administration of blood schizonticidal medicines, such as chloroquine, to suspected cases of malaria, followed by full treatment after confirmation. This plan of action has been abandoned in recent years [45].
