Malaria is one of the main public health challenges in Ethiopia that hinder the productivity and development of the country. In 2018, Ethiopia is on track to minimize the incidence of malaria by 40% as per its 2020 malaria reduction strategy. Currently, Ethiopia is working to eliminate malaria in 2030 by extending the 2020 strategy. Hence, this study aimed to analyze the trend of malaria prevalence in Wolkite health center, Gurage zone, Southern Central Ethiopia from 2015 to 2018. A retrospective study was conducted to determine the prevalence of malaria by reviewing the malaria registration laboratory logbook at Wolkite health center from 2015 to 2018. For all patients, blood films were done for the detection of malaria cases. All the socio-demographic data, year, month and malaria data were collected using a predesigned data collection sheet from January to March, 2019. From a 121,230 clinically malaria suspected patients, the overall prevalence of microscopically confirmed cases were 8.56% (n = 10,379/121,230). Plasmodium vivax was the most predominant species accounted for 69.7% (n = 7237/10,379) followed by Plasmodium falciparum 29.3% (n = 3044/10,379). Age group > 15 years old were more affected by malaria accounting 54% (n = 5609/10,379) and malaria cases regarding sex were proportional (51.1% of males and 48.3% of female). Among the catchment areas, a higher number of malaria prevalence was recorded in the Wolkite town 66.2% (n = 0.6538/10,379). Higher malaria cases were shown in the season of Spring 29.8% (n = 3096/10,379) while lower cases 20.4% (n = 2123/10,379) were seen in the Winter season. The prevalence of malaria in Wolkite health center showed a consistent downward trend from the year of 2015–2018. Importantly, the higher prevalence of P. vivax seems overlooked in the study area. Therefore, malaria prevention and control strategy should be reinforced to reduce the prevalence of malaria in the study area.

Wolkite卫生中心的疟疾流行趋势：对埃塞俄比亚到2030年消除疟疾的影响

疟疾是埃塞俄比亚的主要公共卫生挑战之一，阻碍了该国的生产力和发展。根据其2020年减少疟疾战略，埃塞俄比亚有望在2018年将疟疾的发病率降至40％。目前，埃塞俄比亚正在努力通过扩展2020年战略在2030年消除疟疾。因此，本研究旨在分析2015年至2018年埃塞俄比亚中南部南部古拉格地区Wolkite卫生中心的疟疾流行趋势。通过回顾Wolkite卫生中心的疟疾登记实验室日志，进行了回顾性研究，以确定疟疾的流行情况。从2015年至2018年。对所有患者进行血膜检查以检测疟疾病例。所有的社会人口数据，年份，使用预先设计的数据收集表，于2019年1月至3月收集了一个月的疟疾数据。从121,230名临床疟疾可疑患者中，经显微镜证实的病例的总体患病率为8.56％（n = 10,379 / 121,230）。间质疟原虫是最主要的种类，占69.7％（n = 7237 / 10,379），其次是恶性疟原虫29.3％（n = 3044 / 10,379）。年龄大于15岁的人群受疟疾影响更大，占54％（n = 5609 / 10,379），与性别有关的疟疾病例成比例（男性为51.1％，女性为48.3％）。在集水区中，Wolkite镇的疟疾患病率更高，为66.2％（n = 0.6538 / 10,379）。在春季，疟疾发病率较高，为29.8％（n = 3096 / 10,379），在冬季，疟疾发病率较低，为20.4％（n = 2123 / 10,379）。自2015-2018年以来，沃克特（Wolkite）卫生中心的疟疾流行呈持续下降趋势。重要的是，在研究领域，间日疟原虫的高流行似乎被忽略了。因此，应加强疟疾的预防和控制策略，以减少研究区域的疟疾流行率。
