【摘要】 1986、2002、2004、2006、2007和2008年调查未开展药物驱虫的海南省中部山区五指山市毛阳镇人体土源性肠道线虫感染情况及其影响因素。结果显示,土源性肠道线虫总感染率从1986年的96.4%降至2008年的35.7%,其中钩虫、蛔虫和鞭虫的感染率从84.7%、80.9%和31.8%分别下降至32.5%、0.3%和4.2%,蛔虫和鞭虫感染率下降幅度较大,钩虫下降相对较缓慢。钩虫、蛔虫、鞭虫轻度感染者构成比分别从1986年的56.6%、41.2%和66.9%上升至2008年的97.9%、100%和83.7%,而重度感染者构成比分别从6.8%、11.9%和3.8%下降至0。改水改厕工程逐年增加及受益人口逐年增长,农村居民人均纯收入逐年增加,卫生条件和居住环境得到改善,均是土源性肠道线虫病感染率下降的原因。更多还原

【Abstract】 The epidemiology of soil-transmitted intestinal nematodes were observed in the central mountain area without anti-helminthic therapy from 1986 to 2008. The results showed that the overall prevalence decreased from 96.4% in 1986 to 35.7% in 2008. The prevalence of Ancylostoma duodinale, Ascaris lumbricoides and Trichuris trichura decreased from 84.7%. 80.9%, 31.8% in 1986 to 32.5%, 0.3%, 4.2% in 2008, respectively. The proportion of light infection with Ancylostoma duodinale, Ascaris lumbricoides and Trichuris trichura increased from 56.6%, 41.2%, and 66.9% in 1986 to 97.9%, 100%, and 83.7% in 2008, respectively. While that of heavy infection decreased from 6.8%, 11.9%, and 3.8% in 1986 all to zero in 2008. Water and toilet renovation, rural income increase and the improvement of sanitation and living conditions made the prevalence of soil-transmitted intestinal nematode decreased.更多还原
