Trends in prevalence and incidence of scabies from 1990 to 2017: findings from the global Burden of disease study 2017

Scabies remains a significant public health concern globally, affecting people of all ages, races, and socioeconomic groups. The epidemic characteristics of scabies are yet unravelled, especially in high-income countries and elderly population. In this study, we sought to investigate incidence and prevalence and their trends of scabies worldwide from 1990 to 2017 via the Global Burden of Disease (GBD) Study 2017. The prevalence and incidence of scabies tend to a moderate increase after age 70. The annual percentage change in ASR of scabies prevalence and incidence increased in high SDI countries and High-income North America. Current prevention strategies should be reoriented, and much more targeted strategies should be established in some populations to forestall the increase in scabies.
