Comparison of trend analysis of varicella zoster disease burden between China and the world 1990–2021 and disease burden forecast 2030

Between 1990 and 2021, the incidence, prevalence, mortality, and DALYs of VZV in China demonstrated a declining trend, reflecting a relative reduction in the VZV burden. Women are more susceptible to VZV infection and face a higher risk of mortality than men. In contrast, the global disease burden remains higher than that in China. Projections suggest a slight decrease in the VZV burden in China by 2030. However, due to the country's large and aging population, VZV will continue to pose a significant public health challenge.
