Wastewater-based epidemiology (WBE) is a powerful and cost-effective tool for investigating chemicals consumption/pathogens infection and health status of populations, and is rapidly evolving as COVID-19 continues to ravage the world. This paper reviews the significant developments and breakthroughs of WBE in 2021 including collection, pretreatment and analysis of sewage samples, materials stability, correction factors calculation and uncertainty analysis, implementation cases and so on, based on the research findings published in international top academic journals or the most influential achievements. It provides reference for clarifying the development of WBE and promoting the research and application of WBE.
