Climate Change and Malaria in Canada: A Systems Approach
Figure 2
Geographic distribution of vectors of malaria, cases of local mosquito-borne transmission during the period 1957–2003 Figure 2(a),
population density Figure 2(b), and population change Figure 2(c) in Canada. (a) shows the geographic
distribution of vectors of malaria and cases of local mosquito-borne
transmission during the period 1957–2003. Black dots represent location of cases
of malaria in the United States and Canada presumed to be acquired from local
mosquito-borne transmission between 1957 and 2003 (Source: [1, 38–45]. Each dot
represents one or a cluster of cases in a given year. Labels include species
type (V = P. vivax, F = P. falciparum, M = P. malariae, S = species unknown) and date. Locations are
approximate. Hashed areas represent the approximate distributions of the two
most important competent malaria vectors in Canada. (Sources of malaria data: [1, 30–34]). See Table 2 for
full names of Canadian provinces. (b) and (c): population density
(2001) and population change (1996–2001) in Canada.
