Additional file 6: of Observational study: 27 years of severe malaria surveillance in Kilifi, Kenya

Figure S1. Numbers of admissions to Kilifi County Hospital over time. The percentage of admissions drawn from the Kilifi Health Demographic Surveillance System are shown on the left Y axis. Total annual admissions are shown on the right Y axis. The KHDSS was established in 2001, hence earlier residence in the DSS is reconstructed based on the reported location of residence in the clinical record. Hence the appearance of an expansion in KHDSS residence after 2001 is likely to reflect greater ascertainment of residence. (PNG 151 kb)
