Abstract:

Objective To understand the malaria epidemiologic characteristics in Wuhe County,Anhui Province from 2009
to 2011,so as to provide the evidence for formulating effective malaria control and prevention interventions. Methods The data
of malaria cases from the reporting system and malaria epidemiological investigations were collected and analyzed statistically in
Wuhe County from 2009 to 2011. Results The total number of malaria cases was 349 in Wuhe County from 2009 to 2011,and
the incidence showed a downtrend. The sex ratio of patients was 1.42:1(205 males vs. 144 females). The ranks of patient age
groups were 11?20 years old at the first and 31-40 at the second,and the youngest was 1 year old,and the oldest was 100 years
old. The seasonal factor was observed clearly,malaria cases were rare during the period of January to March,the case numbers in?
creased in April and reached the peak during the period of June to September,and the cases from November to December account?
ed for only 2.01% of the total cases. Among the 349 patients,there were only 2 patients(0.57%)living in urban areas and the rest
347 patients(99.43%)all living in rural areas. The incidence of the urban population was 0.08/10 000,and it was significantly
lower than that of the rural population(1.78/10 000,P < 0.05). The highest incidences occurred in hill townships,Zhuding Town
and Xiaoxi Town,the annual incidences were 5.53/10 000 and 4.78/10 000,respectively. The cases in hill townships accounted
for 36.10% of the total cases. The most patients in these areas lived in brick or cement buildings without mosquito?proof doors or
windows. They preferred sleeping outside during summer,and were generally lack of the malaria prevention knowledge. Conclu?
sion In Wuhe County,the malaria incidence is decreasing year by year,and the epidemiologic factors are related to the living
conditions,mosquito?proof facility using,sleeping habit,and malaria awareness of the residents.

摘要:

目的 分析2009-2011年安徽省五河县疟疾流行特征,为制定行之有效的防治措施提供科学依据。方法 对2009-2011年五河县疟疾疫情报表和流行病学调查资料进行统计学分析。结果 2009-2011年五河县疟疾总发病349例,发病呈逐年下降趋势。其中男性205例,女性144例,男女比例为1.42∶1。年龄最小的1岁,最大的100岁,11~、21~岁2个年龄组发病人数较多。疟疾流行有明显的季节性,1-3月发病较少,4月开始上升,6-9月为发病高峰季节,11-12月仅占2.01%。349例中,县城2例,占0.57%,农村347例,占99.43%。县城人口疟疾年均发病率0.08/万,显著低于农村的1.78/万(P < 0.05)。发病率前2 位为丘陵区的朱顶镇和小溪镇,年均发病率分别为5.53/万和4.78/万,丘陵区占发病总数的36.10%。患者多住平瓦房,纱门、纱窗使用率较低,少有疟防知识且多有露宿习惯。结论 五河县疟疾发病呈逐年下降趋势。疟疾发病与居住条件、疟防知识知晓等因素有关。
