Figure 3.6 Map of malaria situation globally, highlighting drag-resistant areas. (A) P. falciparum absent or sensitive to chloroquine. (B) Low risk in most areas, although chloroquine-resistant P. falciparum malaria does occur. (C) Risk high in most areas of this zone in Africa and also in parts of the Amazon basin. Relatively low elsewhere. Multi drag-resistant P. falciparum malaria occurs. Adapted from World Health Organization (1998)
