According to the scheme of the 3rd National Survey of Principal Human Parasitic Diseases, a survey on Enterobius vermicularis infection among children was performed in Fujian Province in 2015-2017. Based on the ecological category, economic condition and geographical location of the region, all counties (cities) were listed into the east, south, west, north and middle regions of the province respectively, for stratified cluster random-sampling. One to two kindergartens were selected from each region, and E. vermicularis infection was examined in children aged 3-6 years by using the adhesive cellophane anal swab. A total of 3 472 children in 15 counties (cities) were examined, and 205 children were found having E. vermicularis infection, with an infection rate of 5.90%, which was decreased by 87.38% and 73.21% as compared to the first and second surveys, respectively. The prevalence of E. vermicularis was 7.24% (128/1 769) in boys, higher than that in girls (4.52%, 77/1 703) (P < 0.05), and the prevalence showed a trend of increasing with age. The infection rate was highest in the age group of 6 years (7.39%, 95/1 285), and the difference between all age groups was statistically significant (P < 0.05). The infection rate in the economically advanced regions was 4.27% (86/2 016), significantly lower than those in the medium- (7.22%, 52/720) and less-developed regions (9.10%, 67/736). The infection rate in the Zhejiang-Fujian mountainous and hilly ecological regions was 4.48% (58/1 294), significantly lower than that in the Yunnan-Guangxi-central Guangdong-southern Fujian mountainous and hilly ecological regions (6.75%, 147/2 178). The infection rate was significantly lower in public (4.40%, 59/1 340) than in private kindergartens (6.85%, 146/2 132) (P < 0.05). The infection rate of E. vermicularis was highest in Zhangzhou City (15.59%, 63/404) and lowest in Xiamen City (2.51%, 10/398). The results suggest that the infection rate of E. vermicularis was significantly decreased compared to the second survey, but there still need to strengthen the surveillance and control of E. vermicularis infection.
