Abstract

Objective: To investigate the trends in areas of Oncomelania hupensis snail habitats in Anhui Province from 2004 to 2023, so as to provide insights into facilitating the progress of schistosomiasis elimination in the province.

Methods: Areas of O. hupensis snail habitats in Anhui Province from 2004 to 2023 were collected, and the trends in and mutations of O. hupensis snail habitats in Anhui Province, and the trends in O. hupensis snail habitats in different types of schistosomiasis-endemic foci and in different cities of Anhui Province from 2004 to 2023 were analyzed using Mann-Kendall test.

Results: The areas of O. hupensis snail habitats reduced by 12.62% in Anhui Province in 2023 relative to in 2004. Mann-Kendall trend test showed that the areas of O. hupensis snail habitats appeared a tendency towards a decline in Anhui Province from 2004 to 2023 (Z = -3.926, P < 0.001, β = -215.66), with an annual average reduction of 215.66 hm². Mann-Kendall mutation test showed that the areas of O. hupensis snail habitats appeared a tendency towards a decline in Anhui Province since 2015 (|Z| > U_0.05, P < 0.05). The areas of O. hupensis snail habitats appeared a tendency towards a decline in marshland and lake regions (Z = -4.899, P < 0.001, β = -260.13), and a tendency towards a rise in hilly regions of Anhui Province from 2004 to 2023 (Z = 2.758, P < 0.01, β = 44.55). Among 9 cities endemic for schistosomiasis in Anhui Province, the areas of O. hupensis snail habitats appeared a tendency towards a decline in 5 cities of Ma'anshan, Tongling, Anqing, Huangshan and Chizhou (Z = -4.056 to -2.109, all P values < 0.05, β = -92.12 to -0.45). The average constituent ratios of areas of O. hupensis snail habitats were 88.19% and 11.81% in marshland and lake regions and hilly regions of Anhui Province from 2004 to 2023, respectively, and the ratio of areas of O. hupensis snail habitats in marshland and lake regions to areas of snail habitats in hilly regions reduced from 9.23∶1 in 2004 to 5.74∶1 in 2023 in Anhui Province, with the ratio appearing a tendency towards a decline (Z = -4.477, P < 0.001, β = -0.16).

Conclusions: The areas of O. hupensis snail habitats appeared a tendency towards a decline in Anhui Province from 2004 to 2023, with a reduction in areas of O. hupensis snail habitats in marshland and lake regions and a rise in hilly regions. Targeted O. hupensis snail control interventions are required tailored to real snail status.

[基于Mann-Kendall检验的2004 - 2023年安徽省钉螺生境变化趋势]。

目的：了解2004 - 2023年安徽省钉螺分布区钉螺分布趋势，为推进全省消灭血吸虫病工作提供参考。方法：收集2004 - 2023年安徽省血吸虫病流行区，采用Mann-Kendall检验分析2004 - 2023年安徽省不同类型血吸虫病流行疫源地和安徽省不同城市的血吸虫病流行区钉螺生境变化趋势和突变情况。结果：2023年安徽省钉螺栖息地面积较2004年减少12.62%；Mann-Kendall趋势检验表明，2004 - 2023年安徽省钉螺生境面积呈下降趋势（Z = -3.926, P < 0.001, β = -215.66），年平均减少215.66 hm2。Mann-Kendall突变检验结果显示，2015年以来安徽省钉螺栖息地面积呈下降趋势（|Z| > U0.05, P < 0.05）。2004 - 2023年安徽省湖沼区钉螺栖息地面积呈下降趋势（Z = -4.899, P < 0.001, β = -260.13），丘山区钉螺栖息地面积呈上升趋势（Z = 2.758, P < 0.01, β = 44.55）。在安徽省9个血吸虫病流行城市中，马鞍山、铜陵、安庆、黄山、池州5个城市的钉螺栖息地面积呈下降趋势（Z = -4.056 ~ -2.109， P值均< 0.05,β = -92.12 ~ -0.45）。地区的平均构成比o . hupensis蜗牛栖息地的分别为88.19%和11.81%在沼泽地和湖地区和丘陵地区的安徽省从2004年到2023年,分别和o . hupensis领域比蜗牛栖息地在沼泽地和湖地区丘陵地区的蜗牛栖息地减少的地区从2004年的9.23∶1 5.74∶1 2023年安徽省率出现下降的倾向(Z = -4.477, P < 0.001,β= -0.16)。结论：2004 - 2023年安徽省湖北钉螺生境面积呈下降趋势，沼泽和湖泊地区钉螺生境面积减少，丘陵地区钉螺生境面积增加。有针对性的控制钉螺干预措施需要根据实际钉螺状况量身定制。
