我们对 2000 年 1 月至 2007 年 4 月期间赞比亚的人类非洲锥虫病 (HAT) 情况进行了分析。这项调查的目的是确定赞比亚仍在记录 HAT 病例的地区。姆皮卡、查马和奇帕塔三个地区被发现仍在报告 HAT 病例，因此属于赞比亚东北部 HAT 传播疫源地。报告期内，这三个地区共报告了 24 起 HAT 病例。此后，我们回顾了 20 世纪 60 年代初至 90 年代中期赞比亚发生 HAT 的文献。这表明，在此期间，HAT 传播灶在赞比亚西部省、西北省、卢萨卡省、东部省、卢阿普拉省和北部省广泛传播。在本文中，我们试图给出可能的原因，解释为什么 2000 年前后 HAT 传播源的分布如此不同，当时赞比亚还没有积极的国家采采蝇和锥虫病控制计划。 (C) 2010 年皇家热带医学和卫生学会。由爱思唯尔有限公司出版。保留所有权利。
We conducted a situation analysis of human African trypanosomiasis (HAT) in Zambia from January 2000 to April 2007. The aim of this survey was to identify districts in Zambia that were still recording cases of HAT. Three districts namely, Mpika, Chama, and Chipata were found to be still reporting cases of HAT and thus lay in HAT transmission foci in North Eastern Zambia. During the period under review, 24 cases of HAT were reported from these three districts. We thereafter reviewed literature on the occurrence of HAT in Zambia from the early 1960s to mid 1990s. This revealed that HAT transmission foci were widespread in Western, North Western, Lusaka, Eastern, Luapula, and Northern Provinces of Zambia during this period. In this article we have tried to give possible reasons as to why the distribution of HAT transmission foci is so different between before and after 2000 when there has been no active national tsetse fly and trypanosomiasis control program in Zambia.
