Abstract

Background: The World Health Organization (WHO) reported an estimated 249 million malaria cases globally in 2023, of which 94% were reported from Africa. Tanzania, a Sub-Saharan African country, has an exceptionally high malaria prevalence (3.6 million in 2023). The aim of the present study was to assess malaria prevalence rates in the Arusha Region, northern Tanzania. This region is famous for its national parks and wildlife reserves, and it is visited by thousands of tourists from all over the world each year. The assessment of malaria prevalence in the region is important in the context of the necessity to administer antimalarial chemoprophylaxis to international travellers.

Material and methods: The study group consisted of 101 people, residents of the Karatu District in the Arusha Region, aged between 1 and 73 years, who volunteered to participate in the screening. Phase I of the study was conducted in July 2022 in the Karatu Lutheran Hospital in Karatu Town (located close to the Ngorongoro Conservation Area and the Serengeti National Park). During this phase a venous blood sample was collected from each patient. The samples were tested for malaria using a rapid diagnostic test (mRDT); the same samples were also used to measure haemoglobin concentration and next they were applied onto the Whatman FTA micro cards for further molecular diagnostics in Poland (phase II).

Results: mRDT detected two (2.0%) infections caused by Plasmodium (the etiological factor of malaria), the molecular tests (RT-PCR) confirmed the two positive results by mRDT but also detected infections in six other samples (7.9% in total). The study found that six patients were infected with the Plasmodium falciparum species, while two other subjects had co-infections (P. falciparum + P. ovale, P. falciparum + P. vivax + P. malariae).

Conclusions: The study findings confirm the prevalence of malaria in areas located close to national parks in northern Tanzania and support the use of antimalarial chemoprophylaxis in international travellers visiting the area. The present study found co-infections caused by four different species of Plasmodium species which supports the prevalence of different parasitic species in Sub-Saharan Africa and is in line with CDC reports but contrary to WHO reports which estimate that 100% of malaria cases in Sub-Saharan Africa are caused by P. falciparum.

坦桑尼亚北部阿鲁沙地区的疟疾流行情况。
背景:世界卫生组织(WHO)报告称,2023 年全球疟疾病例估计为 2.49 亿例,其中 94% 来自非洲。坦桑尼亚是撒哈拉以南非洲国家,疟疾发病率极高(2023 年为 360 万)。本研究旨在评估坦桑尼亚北部阿鲁沙地区的疟疾流行率。该地区以其国家公园和野生动物保护区而闻名,每年都有成千上万的世界各地游客前来观光。鉴于有必要对国际游客进行抗疟化学预防,因此对该地区疟疾流行情况的评估非常重要:研究对象包括 101 名自愿参加筛查的阿鲁沙地区卡拉图区居民,年龄在 1 岁至 73 岁之间。研究的第一阶段于 2022 年 7 月在卡拉图镇(靠近恩戈罗恩戈罗保护区和塞伦盖蒂国家公园)的卡拉图路德医院进行。在这一阶段,从每位患者身上采集静脉血液样本。结果:mRDT 检测出两例(2.0%)由疟原虫(疟疾的病原体)引起的感染,分子检测(RT-PCR)证实了 mRDT 的两例阳性结果,但也检测出另外六例样本(共 7.9%)的感染。研究发现,六名患者感染的是恶性疟原虫,另外两名患者合并感染(恶性疟原虫+卵形疟原虫、恶性疟原虫+间日疟原虫+疟疾疟原虫):研究结果证实了疟疾在坦桑尼亚北部国家公园附近地区的流行情况,并支持对前往该地区的国际旅行者进行抗疟化学预防。本研究发现了由四种不同种类的疟原虫引起的共同感染,这证实了不同种类的寄生虫在撒哈拉以南非洲地区的流行情况,与疾病预防控制中心的报告一致,但与世界卫生组织的报告相反,该报告估计撒哈拉以南非洲地区的疟疾病例100%是由恶性疟原虫引起的。
