Positive malaria cases and climatic factors per month, May 2010 to April 2012.

<p>Symptomatic <i>P. falciparum</i> infection numbers were correlated with (<b>A</b>) rainfall distribution (R² = 0.252; p = 0.007), (<b>B</b>) average daily minimum temperature (R² = 0.203; p = 0.016), and (<b>C</b>) average daily humidity (R² = 0.261; p = 0.006). Case numbers were not associated with (<b>D</b>) the average daily maximum temperature (R² = 0.002; p = 0.820). Rainfall distribution is defined by the average daily rainfall per month (in mm) multiplied by the number of rainy days in that month.
