Time series of climatic and epidemiological data observed during the simulation periods. (A) Monthly Plasmodium falciparum malaria incidence (IFM: total positive reported cases scaled by the total population at risk) for the Nuqui region along with mean daily temperatures (Daily_T) recorded during the period from November 1st, 1997 to December 31st, 2003 (2,252-day simulation period). (B) P. falciparum (IFEP) and P. vivax (IVEP) malaria incidences recorded in El Bagre, every epidemiological period, during the period from January 3rd, 1994 to December 28th, 2002 (1st EP 1994-13th EP 2002). In this case, the simulation exercise comprises a 3,282-day simulation period. (C) Plasmodium falciparum malaria incidence (IFEP, gray bars) for El Bagre along with mean daily temperatures (T, solid line). Notice in the graphs the strong increasing and decreasing trends. The plots indicate that the increase in the number of P. falciparum malaria cases might be associated with increases in air temperatures.
