  1. Approximate correspondence of SIMS values to values of existing indices, based on a combination of linear models and theoretical maxima and minima. SIMS: Summary Index of Malaria Surveillance; API = annual parasite index; AFI = annual falciparum index; SPR = slide positivity rate; SFR= slide falciparum rate; %Pf = percent of positive slides that are falciparum-positive; ABER = annual blood examination rate; MR = deaths/population
