From: The burden of malaria in Sudan: incidence, mortality and disability – adjusted life – years
Malaria incidence calculation model. Malaria underreporting ratio was calculated using reported episodes in 2000 and results of MICS (Multiple Indicators Cluster Survey) 2000. The number of reported episodes of presumptive malaria in 2002 in northern and southern Sudan was corrected for underreporting, and adjusted downwards to calculate true malaria incidence in each region. Age-sex ratios were used to disaggregate the overall incidence in each region and the incidence in each age-sex group was pooled to estimate the age-sex specific incidence in all Sudan.
