Ten cases were exposed before the confirmed cases they contacted with developed clinical symptoms, and the possibility of exposure to other infection sources was ruled out; two clusters were caused by asymptomatic carriers; confirmed cases mainly presented with fever, respiratory and systemic symptoms; a gradual decline in the severity of clinical symptoms was noted with the increase of the case generation. In this study, information about all local clusters was exported from sub-module "Emergency Public Reporting System" and data about related confirmed cases and asymptomatic carriers from sub-module "Infectious Disease Management Information System".	./cache/cord-262413-jm4qmpeg.txt	./txt/cord-262413-jm4qmpeg.txt
