Table 4 Calculated global 2005 DALY estimates for the four study viruses--yellow fever, Japanese encephalitis, chikungunya, and Rift Valley fever, based on data from previous tables

  1. a NOTE: Total DALY min and max do not sum across the YLL and YLD rows above because gains in one DALY category column (e.g., YLL) are necessarily offset by reductions in survival and reduction in possible YLDs.
