Abstract

Setting: Finding TB among nomads, a high-risk group, can help address the global challenge of missing TB cases. Nigeria accounts for 6.2% of the 3.1 million missing TB cases.

Objective: To describe the outcome of active TB case-finding (ACF) among nomads in Bauchi State, northeastern Nigeria.

Design: KNCV implemented ACF in eight Local Government Areas of Bauchi State from June 2020 to December 2023. Trained community volunteers screened nomads and ensured diagnostic testing of sputum samples of nomads with presumptive TB. Community volunteers helped to link those with confirmed TB to treatment.

Results: We screened 43,070 nomads (35,533 adults; 7,537 children) of which 43% were males. Presumptive TB was detected among 12,387, of whom 850 (6.9%) had active TB, including 61 children. Overall, 99% of people with active TB were put on treatment. Presumptive TB yield was higher among the nomads, but active TB yield was comparable with the general population. Nomads contributed 5% to the total number of people notified with TB from Bauchi State.

Conclusion: ACF among nomads resulted in improved TB notification and can help improve the identification of missing TB cases in Nigeria.

尼日利亚游牧人口中活动性结核病例发现的结果。

背景：在游牧民族这一高风险群体中发现结核病，有助于解决结核病病例缺失这一全球挑战。尼日利亚占310万结核失踪病例的6.2%。目的：描述尼日利亚东北部包奇州游牧民结核病活动性病例发现（ACF）的结果。设计：从2020年6月到2023年12月，KNCV在包奇州的八个地方政府地区实施了ACF。训练有素的社区志愿者对游牧民进行筛查，并确保对疑似患有结核病的游牧民的痰样本进行诊断检测。社区志愿者帮助将确诊结核病患者与治疗联系起来。结果：我们筛选了43,070名游牧民(35,533名成年人；7537名儿童)，其中43%为男性。在12,387人中检出推定结核，其中850人（6.9%）患有活动性结核，包括61名儿童。总体而言，99%的活动性结核病患者得到了治疗。游牧民族的推定结核病产量较高，但活跃结核病产量与一般人群相当。游牧民占包奇州结核通报总人数的5%。结论：尼日利亚游牧民族的ACF改善了结核病通报情况，有助于提高对漏报结核病病例的识别。
