title: [Survey of infection situation of intestinal parasites of rural residents in plain area of Shandong Province].
abstract: OBJECTIVE
  To understand the current situation of infections of intestinal parasites of rural residents in four cities namely Dongying, Weifang, Jining and Heze of Shandong Province.
  
  
  METHODS
  Twenty-four villages were randomly selected as study areas. The Kato-Katz technique was applied to test the stool samples of adult residents and the cellophane tape anus method was applied to test the infection of Enterobius vermicularis of children aged 12 years or below. Fifty families were randomly selected from each village and surveyed with questionnaires for the general situation of the family, and the knowledge of prevention and control of parasites, and healthy behaviors of the family members.
  
  
  RESULTS
  Totally 8,227 adult residents and 1,313 children were investigated and the total infection rate of intestinal parasites was 0.55% (45 cases). The infection rates of Ascaris lumbricoides, hookworm, Trichuris trichura, E. vermicularis and Clonorchis sinensis were 0.15% (12 cases), 0.06% (5 cases), 0.09% (7 cases), 1.37% (18 cases) and 0.04% (3 cases), respectively. Totally 3,767 residents were surveyed with questionnaires, and the awareness rate of the knowledge of prevention and control of parasites was 28.72% (1,082 cases), the formation rates of washing hands before meal, washing hands after toilet, washing fruit and vegetables before eating, and never drinking unboiled water were 60.66% (2,285 cases), 50.17% (1,890 cases), 48.71% (1,835 cases), and 87.07% (3,280 cases), respectively.
  
  
  CONCLUSIONS
  In the plain area of Shandong Province, the infection rates of A. lumbricoides, hookworm, T. trichura and C. sinensis are low but the infection rate of E. vermicularis of children is relatively high; the awareness rates of the knowledge of parasites as well as the formation rates of healthy behaviors are low. Therefore, the health education and promotion should be strengthened.
