Saudi Arabia has successfully reduced malaria cases to be constrained largely in the western regions. This study aimed to determine the epidemiological trends of malaria infection in five western regions of Saudi Arabia.
A retrospective analysis was conducted to investigate the epidemiological trends of malaria infection in the western regions, based on the published registry of the Saudi Ministry of Health, during the period from 2014 to 2017 using the appropriate statistical tools.
A total of 8925 confirmed cases of malaria were reported in the western regions during the period from 2014 to 2017 with the mean of 2231 malaria cases per year. The minimum (n = 1097) and maximum (n = 4075) number of cases were reported in 2014 and 2016 respectively. The highest (n = 5919, 66.3%) number of cases were reported from Jazan region, while lowest (n = 86, 1.0%) number of cases were reported from Al-Bahah region. Plasmodium falciparum was the most frequently reported species with 7485 (83.9%) cases, while Plasmodium vivax accounted 1386 (15.5%) cases. Plasmodium malariae and mixed infections were insignificant and accounted 0.5% (n = 48) and 0.1% (n = 6) cases respectively. In relation to malaria infection and age group, malaria was predominant in > 15 age group. The highest number of malaria cases in almost all years was observed from January until March and the lowest number was reported from May until July.
Plasmodium falciparum was the most dominant species in this survey and Jazan was the most affected region.
沙特阿拉伯已成功将疟疾病例数量减少到主要集中在西部地区。本研究旨在确定沙特阿拉伯五个西部地区疟疾感染的流行病学趋势。
本研究采用回顾性分析方法，基于沙特卫生部发布的登记册，利用适当的统计工具，调查 2014 年至 2017 年期间西部地区疟疾感染的流行病学趋势。
2014 年至 2017 年期间，西部地区共报告 8925 例确诊疟疾病例，平均每年报告 2231 例。2014 年和 2016 年报告的病例数最少（n = 1097）和最多（n = 4075）。报告病例数最多的地区是吉赞地区（n = 5919，66.3%），而报告病例数最少的地区是巴哈地区（n = 86，1.0%）。最常报告的疟原虫种类是恶性疟原虫，有 7485 例（83.9%），其次是间日疟原虫，有 1386 例（15.5%）。疟原虫疟疾病和混合感染的比例较低，分别为 0.5%（n = 48）和 0.1%（n = 6）。与疟疾感染和年龄组的关系，疟疾主要发生在>15 岁年龄组。几乎所有年份的疟疾病例数最多的是 1 月至 3 月，而 5 月至 7 月报告的病例数最少。
恶性疟原虫是本调查中最主要的疟原虫种，而吉赞是受影响最严重的地区。
