The recalcitrance of Mycobacterium tuberculosis (MTB) to eradication was related to achieving a nonreplicating (dormant) state and the increasing global burden of HIV coinfection. Consequently, understanding the knowledge and perception of the population at risk of tuberculosis-HIV infection is essential to designing a strategy of intervention embraced by the target population. A cross-sectional study was conducted among Nomads in Adamawa State, Nigeria. A multistage sampling technique was employed to recruit consented participants. Self-administered questionnaires were used to gather the required information from 4 nomadic schoolteachers in each selected school. Data were entered into a Microsoft Excel sheet where trends and tables of collated data were developed. The findings show that only 13.5% of the participants expressed the correct perceptions of the complementary relationship between HIV and TB. More people in government employment (35%) understand the coexisting relationship of TB-HIV infections. At the same time, cattle herders and crop farmers who practice the prevalent occupation lack knowledge of TB-HIV relatedness. Across gender, only a proportion of males (14.8%) than females (10.5%) were more likely to show an understanding of the complementary association of HIV and TB, and this difference showed statistical significance (p = 0.0001). In conclusion, male gender, education at a degree or professional level, and employment with the government are factors associated with positive perceptions of TB/HIV relatedness. Thus, there is a need to intensify communication to educate Nomads on HIV and TB-related issues., (© 2024. The Author(s).)

Care cascades represent the proportion of people reaching milestones in care for a disease and are widely used to track progress towards global targets for HIV and other diseases. Despite recent progress in estimating care cascades for tuberculosis (TB) disease, they have not been routinely applied at national and subnational levels, representing a lost opportunity for public health impact. As researchers who have estimated TB care cascades in high-incidence countries (India, Madagascar, Nigeria, Peru, South Africa, and Zambia), we describe the utility of care cascades and identify measurement challenges, including the lack of population-based disease burden data and electronic data capture, the under-reporting of people with TB navigating fragmented and privatised health systems, the heterogeneity of TB tests, and the lack of post-treatment follow-up. We outline an agenda for rectifying these gaps and argue that improving care cascade measurement is crucial to enhancing people-centred care and achieving the End TB goals., Competing Interests: Declaration of interests MP serves on the Scientific Advisory Committee of the Foundation of Innovative New Diagnostics (FIND), a non-profit global alliance for diagnostics.

Objectives: This study aimed to assess the practices of private practitioners regarding tuberculosis (TB), and to ascertain factors related to the low contribution of private healthcare providers to TB prevention and care in Nigeria., Design: This is a mixed methods study comprising a quantitative retrospective review and qualitative study., Setting: Private health facilities (HF) in Oyo State and the Federal Capital Territory (FCT), Nigeria., Participants: We used routinely collected data on patients with tuberculosis (TB) notified between 1 January 2017 and 31 December 2018. In-depth interviews were also conducted with the clinical staff of the facilities., Primary and Secondary Outcome Measures: The study outcomes are practices of TB case notification and treatment outcome, as well as the barriers and enablers of TB notification., Results: A total of 13 (11.0%) out of 118 private HF were designated as 'engaged' TB care facilities in Oyo State and none (0%) of the 198 private HF in the FCT held this designation. From the 214 patients with presumptive TB, 75 (35%) were diagnosed with TB, 42 (56%) had a bacteriological test done, 12 (16%) had an X-ray of the chest alone and 21 (28%) had other non-specific investigations. Most patients diagnosed were referred to a public HF, while 19 (25%) patients were managed at the private HF. Among them, 2 (10.5%) patients were treated with unconventional regimens, 4 (21%) were cured, 2 (11%) died, 3 (16%) lost to follow-up and 10 (53%) were not evaluated. The general practitioners did not have up-to-date knowledge of TB with a majority not trained on TB. Most referred patients with presumptive and confirmed TB to the public sector without feedback and were unclear regarding diagnostic algorithm and relevant tests to confirm TB., Conclusion: Most private facilities were not engaged to provide TB services although with knowledge and practice gaps. The study has been used to develop plans for strategic engagement of the private sector in Nigeria., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.
