Climate and ENSO Associations with Malaria Incidence in ColombiaBack to example Figure 1. Evolution of the Annual Parasite Index (API) in Colombia. The API is defined as the ratio between the number of cases reported and the population at risk per 1,000 inhabitants, computed as the total of cases of malaria by Plasmodium vivax (represented by the A.V.I. index) and Plasmodium falciparum (A.F.I. index). Data reported by the Colombian Ministry of Health. From Poveda et al. (2000). Reproduced with the permission of Cambridge University Press.
Back to example Figure 2. Geographical distribution of average annual cycles of P. vivax malaria (black bars) at diverse localities in Antioquia (northwestern Colombia), along with monthly averages during historical El Niño events (red bars), for the period 1980-1997. The annual cycle is depicted in Epidemiological Periods (for practical purposes similar to months), from the June (year 0) to May (year +1). Data source: Antioquia Health Service. From Poveda et al. (2001a). Reproduced with permission from Environmental Health Perspectives.
