REPORTING PROGRESS ON THE USE OF THE WHO 2009 DENGUE CASE CLASSIFICATION: A REVIEW

Abstract

This review reports on the progress in the use of the WHO 2009 dengue case classification--dengue and severe dengue--following up on a previous review (Horstick et al, 2012). The previous review detailed Steps 1 - 5 in developing the 2009 WHO case classification. As a further step, a systematic review of published studies comparing the two classifications has been published with 12 studies and a further 10 expert opinion papers that recommend the use of the 2009 WHO dengue case classification for clinical management, epidemiology, and clinical research. Furthermore, a formal expert consensus was reached in La Habana, Cuba in 2013 with dengue experts from the Americas, sharing experiences that applied the 2009 WHO dengue case classification. The expert panel recommended to 1) update ICD10, 2) include the 2009 WHO case classification in country epidemiological reports globally, and 3) implement studies improving sensitivity/specificity of the dengue case definition.
