Figure 3

Marseille climate diagram for the 1745–1850 period. Average temperatures (solid line) and precipitation (broken line). The horizontal blue and red lines indicate minimal temperatures required for P. vivax (15°C) and P. falciparum (18°C) development, respectively. These figures are not precise thresholds, but they illustrate a climate above which temperatures are generally favourable for transmission.
