DESIGN Data were retrospectively...

The uptake of TB preventive therapy (TPT) for child and adult contacts of index TB patients in Nigeria has been suboptimal. Nigeria introduced the 3-month isoniazid-rifampicin (3HR) shorter regimen TPT for all eligible contacts through the USAID-funded Stop TB Partnership introducing New Tools Project (iNTP). This study assesses the facilitators an...

sec> INTRODUCTION Poor adherence to TB treatment poses a significant public health threat to TB control programmes. The sustainability of directly observed treatment has been questioned because of its non-patient-centred approach and resource-intensive nature, and Digital Adherence Technologies (DATs) provide a suitable alternative. This study asse...

sec> INTRODUCTION Successful treatment of TB requires high levels of adherence to treatment. This has been found to be below optimal with directly observed therapy (DOT), and digital adherence technologies (DATs) offer a promising approach to non-adherence to medication and improving treatment outcomes. This study explores the perception, acceptabi...

Background: In Nigeria, most children with tuberculosis (TB) present at primary health clinics where there are limited personnel skilled in collecting appropriate respiratory specimens from those who cannot produce sputum. KNCV Nigeria, in collaboration with the National Tuberculosis Control Program, implemented a modified simple, one-step (SOS),...

INTRODUCTION TB remains one of the leading causes of death in Nigeria, and despite progress in treatment coverage, a 56% gap in national case notifications remains. This gap is attributable in part to underdiagnosis due to missed cases in health facilities. The TB Surge intervention presented an opportunity to address barriers to optimal case detec...

Setting: KNCV Nigeria implements seven key TB case-finding interventions. It was critical to evaluate the efficiency of these interventions in terms of TB yield to direct future prioritisation in the country. Objectives: To compare the efficiency of active case-finding (ACF) interventions for TB in Nigeria. Design: Data from the 2020-2022 impl...

Background: Undiagnosed tuberculosis (TB) cases are the major challenge to TB control in Nigeria. An early warning outbreak recognition system (EWORS) is a system that is primarily used to detect infectious disease outbreaks; this system can be used as a case-based geospatial tool for the real-time identification of hot spot areas with clusters of...

SETTING: This pilot project was conducted in hard-to-reach communities of two Niger Delta States in the South-South Region of Nigeria. OBJECTIVE: To assess the usefulness of portable digital X-ray, the Delft-Light Backpack (DLB) for TB active case-finding (ACF) in hard-to-reach Niger Delta communities using the WHO 3B TB screening/diagnosis algori...

BACKGROUND Undiagnosed tuberculosis (TB) cases are the major challenge to TB control in Nigeria. Though the Early Warning Outbreak Recognition System (EWORS) is primarily used to detect infectious disease outbreaks, it can be used as a case-based geospatial tool for the real-time identification of hotspot areas with TB patients' residence in cluste...

Aim: To demonstrate the need for routine active TB case finding in Nigerian correctional centers through a TB case surveillance intervention at the largest correctional centre in the most populous state in Nigeria by KNCV Tuberculosis Foundation Nigeria. Study Design: It was a retrospective review of public health intervention data derived from the...

We presented results of a collaboration between KNCV Nigeria and Break-through Action Nigeria towards improving TB screening coverage in Kano state Nigeria

Background: Tuberculosis outbreak occurs when there are more TB cases than expected within

Background: Microscopy is still used in resource-limited countries for PTB diagnosis because of the challenges associated with the GeneXpert instrument. For these settings, the WHO recommended the replacement of microscopy with TB-LAMP for PTB diagnosis in adults. Evidence supporting this recommendation shows a wide variation in quality and TB-LAMP...

Background: Active TB case finding (ACF) is a key strategy employed by the National Tuberculosis and Leprosy Control Programme (NTBLCP) to address the increasing gap in TB case finding in Nigeria. KNCV TB foundation Nigeria rolled out two high-impact ACF interventions; TB Surge and the Wellness on Wheels (WoW) campaigns from January 2020. Method:...

Background: Nearly all countries around the world have felt the great impact of COVID-19, resulting in a global health crisis. The KNCV TB foundation Nigeria-funded by USAID for comprehensive TB care leveraged on existing structure and resources to partner with Kaduna state government to roll out an integrated COVID-19 and TB case-finding intervent...

Text: Background and challenges to implementation: Systematic screening of high-risk groups is a key component of the End TB strategy. TB prevalence surveys show that a significant proportion of prevalent cases were asymptomatic. We explored the use of chest x-ray (CXR) aided with an automated interpretation software, computer-aided detection for t...

Adolescent sexual and reproductive health (ASRH) is a key public health issue because of its impact on health and development. Adolescent SRH is linked to available information which often determines sexual behaviours. The use of mobile phones for health (mHealth) has shown success in delivering health education and behaviour change interventions f...
