In 2016, a total of 9,287 new tuberculosis (TB) cases were reported in the United States; this provisional* count represents the lowest number of U.S. TB cases on record and a 2.7% decrease from 2015 (1). The 2016 TB incidence of 2.9 cases per 100,000 persons represents a slight decrease compared with 2015 (-3.4%) (Figure). However, epidemiologic modeling demonstrates that if similar slow rates of decline continue, the goal of U.S. TB elimination will not be reached during this century (2). Although current programs to identify and treat active TB disease must be maintained and strengthened, increased measures to identify and treat latent TB infection (LTBI) among populations at high risk are also needed to accelerate progress toward TB elimination.
2016年，美国共报告了9287例新发结核病病例；这一临时统计数字是有记录以来美国结核病病例数的最低值，比2015年下降了2.7%（1）。2016年结核病发病率为每10万人2.9例，与2015年相比略有下降（-3.4%）（图）。然而，流行病学模型表明，如果继续保持类似的缓慢下降速度，美国在本世纪内将无法实现消除结核病的目标（2）。虽然必须维持和加强目前识别和治疗活动性结核病的项目，但还需要采取更多措施，在高危人群中识别和治疗潜伏性结核感染（LTBI），以加快实现消除结核病的进程。
