Background. Malaria is a major public health problem in Ethiopia. The trend of malaria occurrence remains unknown in the study area. This study is aimed at determining the last five years' trend of malaria occurrence from 2008/09 to 2012/13 in Wolaita Zone, Southern Ethiopia. Methods. A health facility-based retrospective study was conducted in Wolaita Zone from March to August, 2014. Five years' laboratory confirmed malaria record review was made from six health centers. Result. A total of 105,755 laboratory confirmed malaria cases were reported, with total slide positivity rate of 33.27% and mean annual occurrence of 21,151 cases. Malaria occurred with a fluctuating trend in the study area, with its peak occurring at the year 2011/12. Overall, no remarkable decline in the total laboratory confirmed malaria was observed in the last five years. P. falciparum was the predominantly reported species, accounting for 75,929 (71.80%) of cases. The highest slide positivity rate was observed in the age group of 5-14 years (40.5%) followed by 1-4 years (35.5%). Two malaria peak seasons occurred: one from September to December and the other from April to June. Conclusion. No remarkable decline in laboratory confirmed malaria in the last five years was observed.
背景。疟疾是埃塞俄比亚的一个主要公共卫生问题。研究区域内疟疾的发病趋势尚不清楚。本研究旨在确定2008/09年至2012/13年埃塞俄比亚南部沃莱塔地区过去五年的疟疾发病趋势。方法。2014年3月至8月在沃莱塔地区开展了一项基于医疗机构的回顾性研究。对六个卫生中心五年的实验室确诊疟疾记录进行了审查。结果。共报告了105,755例实验室确诊疟疾病例，总涂片阳性率为33.27%，年平均发病21,151例。研究区域内疟疾呈波动趋势，在2011/12年达到高峰。总体而言，过去五年实验室确诊疟疾总数未见明显下降。恶性疟原虫是报告的主要种类，占病例的75,929例（71.80%）。5至14岁年龄组的涂片阳性率最高（40.5%），其次是1至4岁年龄组（35.5%）。出现了两个疟疾高发季节：一个是9月至12月，另一个是4月至6月。结论。过去五年实验室确诊疟疾未见明显下降。
