Abstract: Objective To analyze epidemic characteristics of reported other infectious diarrhea (other than cholera，dysentery, typhoid and paratyphoid) in Guangdong Province in 2013 so as to provide evidence for preventing and controlling the disease. Methods Epidemiological and pathogenic data of reported cases of other infectious diarrhea were collected from the Infectious Disease Report Information System in China Information System for Disease Prevention and Control from January 1 to December 31,2013. Outbreak data were collected from the Public Health Emergency Management of Information System. Descriptive statistical analysis was performed. Results A total of 166 274 other infectious diarrhea cases were reported in Guangdong Province in 2013 with an annual incidence rate of 156.95/100 000. The cases were distributed across the twenty-one cities in Guangdong. The top five cities by cases were Shenzhen (41 111 cases), Guangzhou (18 900), Meizhou (11 386), Jiangmen (10 704), and Dongguan (10 691), whose cases accounted for 55.81% of the total cases of the province. The cases peaked in January, October, November, and December, accounting for 59.83% of the reported cases（99 485/166 274）. There were 98 356 males and 67 918 females and the male to female sex ratio was 1.45∶1. The children in the age group between 0 and 4 year-old were the main population with infectious diarrhea (130 424 cases, 78.44% of the total cases). The cases were mainly scattered children (130 274 cases, 78.35%). Nineteen outbreaks were reported and all caused by norovirus. There were 76 264 laboratory-confirmed cases accounted for 45.86% of the cases reported and 59 844 confirmed cases have reported the test results, including 58 241 viral cases (97.32% of the total cases) and 1 525 bacterial cases (2.55%)．The main pathogen of viral diarrhea was rotavirus (95.73%，55 756/58 241). The main pathogen of bacterial diarrhea was Salmonella accounting for 81.11% of the bacterial cases（1 237/1 525）. Conclusion The incidence peak of other infectious diarrhea appeared in autumn and winter in Guangdong Province in 2013. The scattered children under 5 years were the high risk group of the infectious diarrhea. All the outbreaks were caused by norovirus. Rotavirus was the main pathogen of the viral diarrhea and Salmonella, the main one of the bacterial diarrhea.
