Acute diarrhea is an important public health issue. Here, we focused on the differences of enteropathogens in acute diarrhea between urban and rural areas in southeast China. Laboratory- and sentinel-based surveillance of acute diarrhea (≥ 3 loose or liquid stools/24 hours) was conducted at 16 hospitals. Fecal specimens were tested for bacterial ( sp., sp., diarrheagenic , , non-typhoidal , sp., sp., and sp.) and viral (adenovirus, astrovirus, , , and ) pathogens. Descriptive statistics were used. Between January 1, 2010, and December 31, 2014, 4,548 outpatients with acute diarrhea were enrolled (urban, = 3,220; rural, = 1,328). Pathogens were identified in 2,074 (45.6%) patients. Norovirus (25.7%), (10.2%), enteroaggregative (EAEC) (8.8%), group A (7.0%), and enterotoxigenic (ETEC) (5.6%) were the most common pathogens. Enteropathogens were less common in urban than in rural areas (42.0% versus 54.4%, < 0.001). In urban areas, EAEC and ETEC were more common in high-income than in middle-income regions. Interventions targeting the most common enteropathogens can substantially reduce the burden of acute diarrhea in southeast China.
