“Richard Cibulskis and colleagues at the WHO in Geneva, Switzerland present a critique of different estimation methods of the worldwide incidence of malaria in this week’s PLoS Medicine,” according to a post in the PLoS Medicine “Community Blog.” The blog states, “In this study, the authors produced their estimate by analyzing routine surveillance reports compiled by national health ministries and conducted a statistical analysis to determine the range of uncertainty of their estimates.” The blog also contains a link to an accompanying perspective in which “Ivo Mueller, Laurence Slutsker, and Marcel Tanner (uninvolved in the research study) highlight the importance of using complementary methods to estimate the burden of malaria and call for a renewed focus on efficient malaria surveillance” (12/20).
