To examine trends of Rocky Mountain spotted fever (RMSF) incidence among American Indians compared with other race groups, a retrospective analysis of national RMSF surveillance data reported to the National Electronic Telecommunications System for Surveillance and the Tickborne Rickettsial Disease Case Report Forms system were used. The RMSF incidence for American Indians, which was comparable to those for other race groups during 1990-2000, increased at a disproportionate rate during 2001-2005. The average annual incidence of RMSF reported among American Indians for 2001-2005 was 16.8 per 1,000,000 persons compared with 4.2, 2.6, and 0.5 for white, black, and Asian/Pacific Islander persons, respectively. Most cases in American Indians were reported from Oklahoma (113.1 cases per 1,000,000), North Carolina (60.0), and Arizona (17.2). The incidence of RMSF increased dramatically among American Indians disproportionately to trends for other race groups. Education about tick-borne disease and prevention measures should be addressed for high-risk American Indian populations.
为了研究与其他种族群体相比，美国印第安人中落基山斑疹热（RMSF）的发病趋势，我们对上报至国家电子电信监测系统和蜱传立克次体病病例报告表系统的全国RMSF监测数据进行了回顾性分析。1990 - 2000年期间，美国印第安人的RMSF发病率与其他种族群体相当，但在2001 - 2005年期间，其发病率以不成比例的速度上升。2001 - 2005年期间，美国印第安人中报告的RMSF年均发病率为每100万人16.8例，而白人、黑人和亚裔/太平洋岛民的发病率分别为每100万人4.2例、2.6例和0.5例。美国印第安人的大多数病例报告来自俄克拉荷马州（每100万人113.1例）、北卡罗来纳州（60.0例）和亚利桑那州（17.2例）。与其他种族群体的趋势相比，美国印第安人中RMSF的发病率急剧上升。对于高危的美国印第安人群体，应开展关于蜱传疾病和预防措施的教育。
