结核病病例在2020年在美国大大下降

（健康日）-in 2020，结核病（TB）案件减少了较大的研究，根据3月26日美国疾病控制和预防中心的研究发表发病率和死亡率每周报告。

来自亚特兰大的CDC，博士，博士，博士，同事描述了结核病的发病率案件在2020年的美国。

The researchers found that 7,163 TB cases were provisionally reported to the CDC National Tuberculosis Surveillance System by the 50 U.S. states and District of Columbia (DC), representing a 20 percent relative reduction compared with 2019. The incidence of TB per 100,000 persons was 2.2 compared with 2.7 during 2020 and 2019, respectively. Overall, 39 states and DC, eight states, and three states reported a decrease in cases, an increase in cases, and no change, respectively. The highest number of cases was reported in California (1,703 cases), while the highest incidence was seen in Alaska (7.9 cases per 100,000 persons). Pandemic mitigation efforts and reduced travel could have contributed to this decline, although the magnitude and breadth of the decrease suggests potentially missed or delayed diagnoses.

“进一步的工作正在进行中，以检查报告的结核病病例中陡峭减少的原因，”作者写道。“识别2020年期间TB病例实际减少的可逆原因或实际降低的实际原因将有助于确定有效的公共卫生反应。”
