Background: Subclinical pulmonary tuberculosis, which presents without recognisable symptoms, is frequently detected in community screening. However, the disease category is poorly clinically defined. We explored the prevalence of subclinical pulmonary tuberculosis according to different case definitions.

Objectives: Antimicrobial resistance (AMR) is a consequence of inappropriate actions, including irrational antimicrobial prescribing and use. Antimicrobial resistance remains an emergent and significant public health threat, particularly in low and middle-income countries (LMICs), including Nigeria. Optimizing antimicrobial (AM) use through functional hospital antimicrobial stewardship (AMS) programs is one of the strategies to control the spread of AMR.

Background: The current pandemic of coronavirus disease (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has shown epidemiological and clinical characteristics that appear worsened in hypertensive patients. The morbidity and mortality of the disease among hypertensive patients in Africa have yet to be well described.

Methods: In this retrospective cohort study all confirmed COVID-19 adult patients (≥18 years of age) in Lagos between February 27 to July 62,020 were included.

Introduction: Lagos state remains the epicentre of COVID-19 in Nigeria. We describe the symptoms and signs of the first 2,184 PCR-confirmed COVID-19 patients admitted at COVID-19 treatment centers in Lagos State. We also assessed the relationship between patients' presenting symptoms, sociodemographic and clinical characteristics and COVID-19 deaths.

The development of an educational concept of a training programme for infection prevention and control (IPC) was seen as a key issue to successfully address the complexity of change processes of professional IPC routines in clinical procedures. Therefore, the Nigeria Centre for Disease Control (NCDC), Nigeria, and the Robert Koch Institute (RKI), Germany established an interdisciplinary project framework, involving knowledge and competences from different disciplines and professions like health professionals, epidemiologists and educators (MAURICE project). A multi-module training programme for health care workers to improve IPC standards was developed and implemented based on the participatory approach and a systemic view for organizational change.

Background: The study was conducted in three major leprosy referral hospitals in Northern Nigeria, which are NKST Rehabilitation Hospital, Benue State, Yadakunya Leprosy Hospital, Kano, and National Tuberculosis/Leprosy Training Hospital, Zaria. The main objective of the study was to investigate factors responsible for the occurrence of ulcers among leprosy patients reporting to the leprosy referral hospitals.

Materials And Methods: An analytic study of case-control design was used, with patients having plantar ulcers as cases and those without as control.

Methods: All State TB control programmes in Nigeria were requested to submit 25-50 smear-positive Ziehl-Neelsen (ZN) stained slides for screening during 2013-2014. DNA was extracted from 929 slides for spoligotyping and drug-resistance analysis using microbead-based flow-cytometry suspension arrays.

Results: Spoligotyping results were obtained for 549 (59.

Introduction: The Ebola virus disease (EVD) outbreak in Nigeria began when an infected diplomat from Liberia arrived in Lagos, the most populous city in Africa, with subsequent transmission to another large city.

Methods: First-, second-, and third-generation contacts were traced, monitored, and classified. Symptomatic contacts were managed at Ebola treatment centers as suspected, probable, and confirmed EVD cases using standard operating procedures adapted from the World Health Organization EVD guidelines.

Background: A major impediment to the treatment of TB is a diagnostic process that requires multiple visits. Descriptions of patient costs associated with diagnosis use different protocols and are not comparable.

Methods: We aimed to describe the direct costs incurred by adults attending TB diagnostic centres in four countries and factors associated with expenditure for diagnosis.

Objective: Underdetection of TB is a major problem in sub-Saharan Africa. WHO recommends countries should have at least 1 laboratory per 100,000 population. However, this recommendation is not evidence based.

Tuberculosis (TB) is a global public health problem, with the highest burden occurring in low-income countries. In these countries, the use of more sensitive diagnostics, such as Xpert MTB/RIF (Xpert), is still limited by costs. A cost-saving strategy to diagnose other diseases is to pool samples from various individuals and test them with single tests.

Background: Adverse events (AEs) of second line anti-tuberculosis drugs (SLDs) are relatively well documented. However, the actual burden has rarely been described in detail in programmatic settings. We investigated the occurrence of these events in the national cohort of multidrug-resistant tuberculosis (MDR-TB) patients in Nigeria.

Background: Chest-x-ray is routinely used in the diagnosis of smear negative tuberculosis (TB). This study assesses the incremental cost per true positive test of a point-of-care digital chest-x-ray, in the diagnosis of pulmonary mycobacterial infections among HIV patients with presumed tuberculosis undetected by smear microscopy.

Methods: Consecutive patients with clinical suspicion of pulmonary tuberculosis were serially tested for Human immunodeficiency virus (HIV), their sputum examined for Acid Fast Bacilli then cultured in broth and solid media.

With an annual new case detection of 4000 people, a Grade 2 disability rate of 12%, and nearly 10% child ratio among new cases, leprosy remains a disease of public health importance in Nigeria. Faced with the reality of low endemicity; a declining budgetary allocation to leprosy control; and a pervasive loss of expertise; it is necessary for Nigeria to re-organise its leprosy control services to further reduce the burden of the disease and ensure quality care to people affected by leprosy.
