The investigation of the crowd geohelminthes infection status in Ningxia

Objective To understand current crowd geohelminthes(roundworm,whipworm,hookworm and pinworm) infection status in Ningxia,and to provide a scientific basis for the future focus on prevention and control work.Methods The stratified cluster random sampling method was used for survey,46 survey points were selected in 2011,survey Kato-Katz thick smear method for detecting ascaris eggs in faeces,whip worm eggs,pinworm eggs,cellophane anal swab method to detect pinworm eggs for children 3 to 14 years.Results A total of 34,023 people were investigated,soil-transmitted nematodes total infection rate of 3.40%.Among them,30,241 copies stool were detected by microscopic examination,the detection of two kinds of soil-transmitted nematode(roundworm,whipworm),were not detected in the hookworm.Roundworm infection rate of 3.49%,there were significant differences about the infection rate between regions(χ2=3784.63,P 0.05),the infection rate in 5 to 9-year-old group was significantly higher than other age groups(χ2=108.46,P 0.05);whipworm infection rate of 0.29%;children pinworm infection rate of 2.69%.Conclusion Need to be strengthened soil-borne worm disease prevention and control work in high-infection areas of the southern mountain in the future,especially under the age of 14 children,farmers and other key groups,to further reduce the infection rate.
