Casey Barber, Lung-Chang Chien, Brian Labus (Epidemiology and Biostatistics), Edwin Oh (School of Medicine and the College of Sciences), Lung-Wen Antony Chen (Environmental and Global Health), and colleagues published an article on "Application of joinpoint regression to SARS-CoV-2 wastewater-based epidemiology in Las Vegas, Nevada, USA" in the journal Epidemiology and Infection.

Using joinpoint regression, this study identified significant positive and negative trends and trend turning points in sewershed-specific SARS-CoV-2 RNA wastewater concentrations and COVID-19 confirmed case rates between June 2020 and April 2023. These findings guide future applications of advanced statistical methodologies and support the continued integration of wastewater-based epidemiology as a complementary approach to traditional COVID-19 surveillance systems.
