概括

在中国,土壤传播的虫病感染率从2016年到2020年大幅下降. 然而,热点仍然存在,特别是在中国西南部,需要本地化控制战略.

科学领域:

* * 公共卫生公共卫生
* 传染病传染病
* 流行病学流行病学

背景情况:

*土壤传播的虫病 (STH) 是全球健康的重大负担,特别是在中国流行.
*从2016年到2020年的全国监测旨在了解中国的STH流行,趋势和影响因素.

研究的目的:

*分析2016年至2020年中国土壤传播的虫病的流行率和变化趋势.
* 确定影响STH分布的关键因素,并为未来的控制策略提供信息.

主要方法:

*在31个省份使用修改的Kato-Katz方法进行全国性便样本检查.
*使用了空间自相关,热点分析 (ArcGIS) 和时空扫描统计 (SaTScan).
*机器学习模型 (LR,RF,GBM,XGBOOST) 分析了STH感染与环境/人为因素之间的关系.

主要成果:

*从2016年到2020年,整体STH感染率下降了65.85%.
*高患病率地区集中在中国南部和西南部,空间和时间聚合.
* 随机森林模型确定了地形,赤脚农业,温度季节性和卫生所覆盖率作为关键影响因素.

结论:

*中国的STH感染率正在下降,原因是控制措施和经济发展.
*高感染率地区的持续的时空聚合需要量身定制的局部控制策略.
*根据当地影响因素和流行情况调整控制措施对于消除STH至关重要.

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
