尽管斯里兰卡有相对较好的国家病例报告系统,但疟疾分布的详细地图尚未公开。在这项研究中,1995 年至 2000 年期间每月记录的显微镜证实的疟原虫阳性血涂片读数(分区空间分辨率)被用来绘制全岛疟疾分布图。此外,还显示了 1995 年至 2002 年期间按地区分辨率划分的年度疟疾趋势。地图显示,间日疟原虫疟疾发病率在全岛分布上存在显着变化。恶性疟原虫疟疾的发病率遵循类似的空间模式,但通常远低于间日疟原虫。在北方,疟疾在年初出现一个季节性高峰,而在南方,六月左右的第二个高峰更为明显。本文提供了斯里兰卡岛上第一份以分区分辨率公开的间日疟和恶性疟发病率分布图,这可能有助于卫生专业人员、旅行者和旅行医学专业人员评估斯里兰卡的疟疾风险。由于疟疾的发病率随着时间的推移而变化,因此有必要定期更新这些地图。
Despite a relatively good national case reporting system in Sri Lanka, detailed maps of malaria distribution have not been publicly available. In this study, monthly records over the period 1995 – 2000 of microscopically confirmed malaria parasite positive blood film readings, at sub-district spatial resolution, were used to produce maps of malaria distribution across the island. Also, annual malaria trends at district resolution were displayed for the period 1995 – 2002. The maps show that Plasmodium vivax malaria incidence has a marked variation in distribution over the island. The incidence of Plasmodium falciparum malaria follows a similar spatial pattern but is generally much lower than that of P. vivax. In the north, malaria shows one seasonal peak in the beginning of the year, whereas towards the south a second peak around June is more pronounced. This paper provides the first publicly available maps of both P. vivax and P. falciparum malaria incidence distribution on the island of Sri Lanka at sub-district resolution, which may be useful to health professionals, travellers and travel medicine professionals in their assessment of malaria risk in Sri Lanka. As incidence of malaria changes over time, regular updates of these maps are necessary.
