Background: The unprecedented COVID-19 pandemic has become an endemic disease of global public health importance. Mass COVID-19 vaccination has been an essential global control strategy amidst challenges of limited acceptance. Because of globalization, COVID-19/similar diseases vaccination acceptance and the determinants in any particular setting are important global public health issues.

Background: Lassa fever is a viral haemorrhagic fever with few options for diagnosis and treatment; it is also under-researched with knowledge gaps on its epidemiology. A point-of-care bedside test diagnosing Lassa fever, adhering to REASSURED criteria, is not currently available but is urgently needed in west African regions with high Lassa fever burden. We aimed to assess the validity and feasibility of a rapid diagnostic test (RDT) to confirm Lassa fever in people in Nigeria.

Background: COVID-19 continues to be a disease of global public health importance and requires long-term management and control. Health workers' (previous) experiences and perceptions regarding the COVID-19 pandemic and COVID-19 vaccination/vaccination process will influence not only their subsequent use of control measures but also public experiences/perceptions. We explored the COVID-19 and COVID-19 vaccination and the vaccination process experiences and perceptions, and their predictors, among the health workers in Ebonyi state, Nigeria.

The COVID-19 pandemic has changed into an endemic COVID-19 disease and health workers continue to be at high risk. The situation requires continued use of COVID-19 control measures by health workers and this will likely depend on their sources of information/knowledge/attitude about COVID-19 and previous use of COVID-19 control measures. We explored the COVID-19 information sources, knowledge, attitude, control practices, and the predictors, among health workers in Ebonyi state, Nigeria.

Background: COVID-19 is still a disease of global public health importance which requires long term application of control measures as millions of new infections or re-infections and thousands of related deaths still occur worldwide and the risk of an upsurge from new strains of the virus continues to be a threat. The decrease in the use of and non-use of preventive public health measures are among the factors fuelling the disease. The (previous) experiences and perceptions of people regarding the COVID-19 pandemic, COVID-19 vaccination, and the vaccination process are factors that will influence subsequent use of preventive/control measures.

Background: Globally, interest in surgical diseases in the elderly was rekindled recently mainly due to a surge in the aging population and their increased susceptibility to infections. In sub-Saharan Africa, infective diseases are major causes of high morbidity and mortality especially in elderly cohorts, hence this study was set to evaluate current status of this scourge in the elderly in our environment.

Aim: To document the aetiologic factors and analyze the impact of selected clinical and perioperative indices on mortality and morbidity rates of peritonitis in the elderly.

Introduction: Health workers have increasingly become victims of workplace violence. However, negligible action has been given to developing workplace violence (WPV) prevention programs in hospital settings in low-middle-income countries. An effective workplace violence prevention program is crucial for preventing violence and managing the consequences of incidents.

Introduction: Vaccine-preventable infectious diseases (VPDs) are major causes of morbidity/mortality among children under 5 years of age worldwide and in Nigeria/Ebonyi state. Routine childhood immunisation is an invaluable prevention strategy for many VPDs. Due to suboptimal coverage and untimely receipt/delay in receipt of vaccinations, outbreaks of VPDs such as measles, yellow fever, diphtheria and others continue to reoccur around the world and in Nigeria/Ebonyi state.

Objectives: Health workers are at particular risk of contracting the COVID-19. However, non-acceptance of COVID-19 vaccination has been a noticeable challenge the world over and in Nigeria where supply constraints have also been an issue. We evaluated COVID-19 vaccination acceptance (the uptake, hesitancy, intention to receive and timeliness of the intention to receive) and the determinants, and the predictive power of acceptance factor compared with availability/access factor, among health workers in Ebonyi state.

Article Synopsis
  • The study focuses on the emergence and dissemination patterns of the SARS-CoV-2 B.1.1.318 and B.1.525 (Eta) variants in Nigeria and Africa, highlighting their significance for public health policies during a pandemic.
  • By combining genomic and travel data, the research indicates that both variants originated from within Africa, with B.1.525 emerging specifically in Nigeria before spreading globally.
  • The findings emphasize the importance of understanding regional connectivity and bidirectional transmission in Africa, revealing that the risks of virus importation between countries have been underestimated.

Introduction: The COVID-19 pandemic has gravely affected the lives and economies of the global population including Nigeria. The attainment of herd immunity through mass COVID-19 vaccination is the foremost control strategy, however, the deployments of COVID-19 vaccinations are facing challenges of non-acceptance. Despite the efforts of the Nigerian government and COVAX facility in making COVID-19 vaccination more available/accessible, the vaccination rate remains unexpectedly very low in Nigeria/Ebonyi state.

Objective: To compare the analgesic efficacy and safety of paracervical block and conscious sedation in the surgical evacuation of the uterus following a first-trimester miscarriage.

Methods: This is an open-label, randomised control trial comparing pain relief by paracervical block versus conscious sedation during manual vacuum aspiration of first-trimester incomplete miscarriages. One-hundred and sixty-two women were equally randomised into two groups.

Introduction: Nurses are the largest healthcare workforce and are not immune to intimate partner violence (IPV) and its consequences.

Objective: This study is aimed at determining the prevalence, types of IPV, and its determinants among female nurses and nursing students in a tertiary teaching hospital in Abakaliki, Ebonyi State, Nigeria.

Methods: This cross-sectional study was done in a teaching hospital in Abakaliki between 1st March 2018 and 31st May 2018 to evaluate the prevalence of IPV in the past 12 months among 460 female nursing students and 460 nurses in the facility.

Background: Healthcare workers are a burnout-prone occupational group and the prevalence is particularly high among physicians. With the prevailing low physician-patient ratio in Nigeria which has worsened with the recent wave of physician emigration, among other socio-economic constraints; a setting for high physician burnout may have been nurtured. Our survey set out to determine the prevalence of burnout among physicians practicing in Nigeria, ascertain the factors that were associated with the development of burnout and evaluate the respondents' perceived impact of physician burnout on patient safety.

Background: Surgical outcomes study for individual nations remains important because of international differences in patterns of surgical disease. We aimed to contribute to data on post-operative complications, critical care admissions and mortality following elective surgery in Nigeria and also validate the African Surgical Outcomes Study (ASOS) surgical risk calculator in our adult patient cohort.

Materials And Methods: We conducted a 7-day, national prospective observational cohort study in consented consecutive patients undergoing elective surgery with a planned overnight hospital stay following elective surgery during a seven-day study period.

Background: To determine the incidence of Postoperative nausea and vomiting (PONV) in a high risk surgical group following studies in other predominately black populations that showed a lower rate of postoperative nausea and vomiting than that reported from Caucasian and Oriental populations.

Methods: A retrospective observational survey was conducted in the University of Nigeria Teaching Hospital (UNTH), Enugu, Nigeria to determine the incidence of PONV within forty-eight hours of anesthesia in an obstetrical (caesarean sections only) and gynecological population that underwent regional and general anesthesia. The study took place from December 2007-April 2009 (16 months) for the gynecological population and from May 2008 to May 2010 (25 months) for the obstetrical population.
