Objective To investigate the epidemiology of infectious diarrhea other than cholera, dysentery, typhoid and paratyphoid （CDTP） in Baoan District of Shenzhen during the period of 2006 - 2010, and to provide reference for preventing and controlling infectious diarrhea other than CDTP.

The proportions of scattered children in children cases of each year were all more than 90 %. The proportions of workers in adult eases of each year were all more than 60 %. The outbreak mainly occurred between October and November. The laboratory con- firmed cases accounted for 84.72 % of the total cases, and the cases of rotavirus infection accounted for 77.32 % of the laboratory confirmed eases.
