The number of days per year which could support infectious P. vivax vectors map in 2010 globally

The number of days per year which could support infectious vectors was calculated using a dynamic biological model and spatial time series temperature data. The temperature data used was a continuous time series across an average year (1950-2000) for every approx. 1km2.

The biological model incorporates the impact of temperature on 1) vector lifespan and 2) the duration of Plasmodium vivax sporogeny. If the temperature at a site never allows mosquitoes to survive long enough to support sporogeny then the area is unsuitable and is shaded grey.
