Imported malaria in Rio de Janeiro state between 2007 and 2015: an epidemiologic approach

Imported malaria is a malaria infection diagnosed outside the area where it was acquired and is induced by human migration and mobility. This retrospective study was performed based on secondary data from 2007 to 2015. In total, 736 cases of imported malaria (79.7% of 923 cases) were recorded in Rio de Janeiro state. Of the imported cases, 55.3% came from abroad, while 44.7% came from other regions of Brazil. Most cases of imported malaria in Brazil (85.5%) originated in Amazônia Legal, and Burundi (Africa) accounted for 59% of the cases from abroad. Analyses of the determinants of imported malaria in Rio de Janeiro state must be continued to understand the relationship between the origin and destination of cases.

输入性疟疾（Imported malaria）指在感染原发地以外区域被诊断出的疟疾感染，其发生由人类迁徙与流动引发。本回顾性研究基于2007年至2015年的二手数据开展。里约热内卢州（Rio de Janeiro state）累计记录736例输入性疟疾病例，占该州923例总病例的79.7%。在上述输入性病例中，55.3%来自境外，44.7%来自巴西国内其他地区。巴西境内的输入性疟疾病例中，85.5%源自法定亚马逊区域（Amazônia Legal）；境外输入病例里，来自非洲布隆迪的病例占比达59%。仍需持续开展针对里约热内卢州输入性疟疾影响因素的分析，以明晰病例来源与感染目的地之间的关联。
