Chante Karimkhani and colleagues1 highlighted the substantial burden of scabies, reporting that scabies accounted for 0·21% of disability-adjusted life-years (DALYs) from all conditions globally in 2015. Although the documentation of global morbidity is timely, the contribution of scabies to mortality is yet to be elucidated. Karimkhani and colleagues' DALY calculations were unable to take into account years of life lost (YLL); instead, a null mortality was assumed. Furthermore, scabies was attributed a maximum disability severity of 1, corresponding to itch or pain, which potentially under-represents its severity as a complex disease process.
