Seasonal transmission in Bobo-Dioulasso. Monthly mean EIR rates (EIR
) for (a) LMM2010 (b) rural VECTRI (density 32.2 km-2) and (c) urban VECTRI (density 1037 km-2). The large letter ‘X’ highlights the month in which the model produces a maximum in EIR. The start (‘S’), peak (‘X’) and end (‘E’) months for transmission measured in various field campaigns are marked in smaller font. The rural observations (brown) are placed on the left of the square of a particular month, the irrigated observations (blue) in the middle and the urban observations (black) to the right.
