Treatment costs in both high and low incidence districts formed the highest cost driver for households.
These districts ranked second and eighth respectively among the top ten districts that reported cases and where selected as high and low incidence districts respectively.
Similar to the national-level results, both early incidence (national, district, and averaged over neighbors) and wind and dust information (national and district) contributed to the fit of the model, with wind and dust information having the greater influence.
The best model with respect to these criteria and AIC, pseudo- R, and CVC (Table 2) is model 9, which includes early incidence (national, district-level, and average of neighbors) and climate (national and district-level deviations from the national-level zonal wind and dust concentration), population density, and a district-specific intercept.
We used Poisson models to test the variability of annual incidences within district years (Wald test) and to test the difference of annual incidences between health centres with and without localised epidemics.
Quartiles of CXR+Pn incidence by districts are shown on choropleth maps.
The negative value of E t may be partly an artifact of our simple model, which does not distinguish between early incidence within remote districts and districts that are nearby but not neighboring (and whose influence is not included within –e it).
Relying on previous spatial analysis of BU incidence in Akonolinga District, we analyzed a series of cases that occurred in the highest BU-risk area of the district, located along the Nyong River upstream of Akonolinga (3 ).
In 2003, the P. vivax incidence in San Juan district was estimated at 0.39 infections/person/malaria seasons but has probably declined since 2007 thanks to the malaria control efforts [2], [4].
However, the incidence in each district varied during the 10-year study period.
