Urban students living environment and health habits are somewhat different from rural students, the cause of the infection of intestinal worms, the existing information and more rural population as the research object, to provide clues to study the cause of urban population, this article in March 1990 By June, six primary school students in our downtown area were compared with roundworm and whipworm infections. 1 research methods to six primary school fecal insects egg-positive 149 were positive group, the other the same class with the same gender students of the same age as a negative control.
