(1) Background: infection causes a significant health burden in children. The infection occurs throughout the country and remains a serious public concern in China. Therefore, it is necessary to know the situation of infection, to provide a scientific basis for the disease control and the optimum conditions for children's growth. (2) Methods: Descriptive epidemiological analysis was implemented to demonstrate the status and changing trend of infection from 2016 to 2020, while the spatial distribution characteristics and spatial-temporal clustering were illuminated by spatial autocorrelation analysis and spatio-temporal scanning analysis. (3) Results: The infection of showed a fluctuating downward trend with a decline of 32.00% in 2020 compared to that in 2016 and was concentrated in central and southern China. There was no significant difference in infection rate between boys and girls, while the high infection rate was presented in 4-, 5- and 6- year-old children. The hotspots and spatial clustering areas were mainly concentrated in southern China. (4) Conclusions: From 2016 to 2020, the infection rate of in children aged 3 to 9 years in China demonstrated a declining trend, and its distribution showed spatial clustering, mainly in southern China. Therefore, it is necessary to strengthen surveillance and implement control measures in combination with health education and environmental improvement.
(1) 背景：感染给儿童带来了沉重的健康负担。这种感染在全国范围内都有发生，在中国仍然是一个严重的公共问题。因此，有必要了解感染情况，为疾病防控提供科学依据，为儿童成长创造最佳条件。(2) 方法：采用描述性流行病学分析方法展示2016年至2020年感染的现状和变化趋势，同时通过空间自相关分析和时空扫描分析阐明其空间分布特征和时空聚集情况。(3) 结果：感染呈现出波动下降趋势，2020年相较于2016年下降了32.00%，且集中在中国中部和南部地区。男孩和女孩的感染率没有显著差异，而4岁、5岁和6岁儿童的感染率较高。热点地区和空间聚集区域主要集中在中国南部。(4) 结论：2016年至2020年，中国3至9岁儿童的感染率呈下降趋势，且其分布呈现空间聚集性，主要集中在中国南部。因此，有必要加强监测，并结合健康教育和环境改善实施防控措施。
