目的了解广州市荔湾区人群肝吸虫感染状况。方法采用改良加藤氏厚涂片镜检法对本辖区人群粪标本进行检测,并对检查结果进行分析。结果共检测1 018份粪标本,阳性率为5.60%(57/1 018),感染人群年龄主要集中在41~60岁。女性阳性率3.30%(16/486)远低于男性阳性率7.71%(41/532),差异有统计学意义(χ2=10.129,P<0.05)。原芳村区域人群感染肝吸虫明显高于原荔湾区域人群(χ2=6.344,P<0.05)。经Logistic多因素回归分析显示,肝吸虫感染主要与性别、年龄有关(P<0.05)。结论荔湾区肝吸虫感染较高,食品卫生亟待加强,需政府及多部门联防联控。
Objective To understand the prevalence of hepatic flukes in Liwan District of Guangzhou City. Methods The modified Kato’s thick smear microscopy was used to detect the fecal specimens in the area and the results of the examination were analyzed. Results A total of 1 018 fecal samples were detected. The positive rate was 5.60% (57/1 018). The age of infection was mainly between 41 and 60 years old. The positive rate of female was 3.30% (16/486), which was much lower than that of male (7.71%) (41/532). The difference was statistically significant (χ2 = 10.129, P <0.05). In the former Fangcun area, the prevalence of hepatic fluke was significantly higher than that of the original Liwan area (χ2 = 6.344, P <0.05). Logistic regression analysis showed that the prevalence of hepatic flukes was mainly related to gender and age (P <0.05). Conclusion Liwan District, higher infection of liver flu, food hygiene needs to be strengthened, requiring government and multi-sectoral joint control.
