Abstract:
Objective To understand and analyse the epidemic status of human intestinal nematode infection in Jiangsu Province, so as to provide basis for making control measures. Methods The typical thirty-nine spots in thirteen counties among the sampling spots of National Investigation on Distribution of Human Parasites in 1990 were selected and investigated according to the Methods of National Investigation Scheme on Human Principal Parasites in 2004. Results The total prevalence was 3.88%, which decreased by 46.92% compared with the investigation in 2002 (7.31%). The infection rates of hookworm, Ascaris and Trichuris were 1.14%, 1.06% and 1.73%, respectively, and the proportion of light infection was 91.75%. The rate of multiple infections was 9.40%. The proportion of hookworm infection was 78.06% in Southern Jiangsu and the proportion of Ascaris or Trichuris was 89.03% in Northern Jiangsu. The infection rate of Enterobius was 3.72% among children aged less than 12 years. Conclusions The prevalence of intestinal nematodes has decreased to lower level in Jiangsu Province. The difference of prevalence in different regions has a relationship with the disease control and social-economic, culture and health levels. The principal control work should be still put in the northern part of Jiangsu Province. The preschool children and the middle and old age peasants are high-risk population. The different control measures should be taken in accordance with the situation of different regions in the future.
