Oral human papillomavirus infections in Zambian Rural and Urban residents-a community cross-sectional study.

Background: How common it is with the presence of human papillomavirus (HPV) in the healthy and diseased oral cavity is largely unknown for Africans. In this cross-sectional study we assessed the prevalence of oral HPV and the risk factors associated with HPV contraction including sexual practice in the urban and rural Zambian population.

Methods: Urban (N = 188) and rural (N = 211) Zambian adults aged 21 years and older living in Ndola and Mansa, respectively, were interviewed about demographical data, oral and coital sexual history and tobacco and alcohol use.

Marburg Virus Reaches Rwanda: How Close Are We to a Vaccine Solution?

Marburg virus disease (MVD) is a highly virulent and often fatal disease caused by the Marburg virus, a member of the Filoviridae family, closely related to the Ebola virus. Historically, outbreaks have been sporadic but lethal across various African countries, with high case fatality rates (CFRs). In 2023, significant outbreaks occurred in Tanzania and Equatorial Guinea, with CFRs of 62.

Contribution of fish to food and nutrition security in Southern Africa: challenges and opportunities in fish production.

This study investigated the role of fish in addressing food and nutrition security challenges in Southern Africa, focusing on 10 countries including Angola, Zambia, Malawi, Mozambique, Namibia, Botswana, Zimbabwe, Lesotho, Eswatini, and South Africa. It examined the current state of food and nutrition security, fish production, and fish consumption patterns. Additionally, the study investigated the challenges and opportunities to enhance fish production in these countries thereby enhancing food and nutrition security.

Occupational exposure to respirable crystalline silica at an underground copper mine in Zambia.

Introduction: Overexposure to respirable crystalline silica (RCS) can lead to the development of silicosis and other respiratory diseases. The mine under study was reported to have the highest number of certified cases of pneumoconiosis in Zambia in 2015, and in 2008, a study revealed that 56% of the RCS samples exceeded 0.05 mg/m3.

Assessment of catchment water resources allocation under climate change in Luwombwa sub-catchment, Zambia.

The uncertainty in climate change and high water demand pose pressure on the natural water resources supply. Not only does this require better understanding but also a call for immediate interventions, mitigation and adaptive measures. This study evaluates catchment water resources in the Luwombwa sub-catchment in Zambia through statistical analysis in the downscaling of past, present and future climatic variables from the CMIP6 climatic model.

ticks: new hosts for phleboviruses.

Ticks are widespread arthropods that transmit microorganisms of veterinary and medical significance to vertebrates, including humans. , an ixodid tick frequently infesting and feeding on humans, may play a crucial role in transmitting infectious agents across species. Despite the known association of many ticks with phleboviruses, information on is lacking.

Molecular detection and phylogenetic characterization of in ticks collected from leopard tortoise () in rural Zambia.

In sub-Saharan Africa, limited studies have investigated zoonotic pathogens that may be harboured by ticks infesting reptiles such as tortoises. Here, we report the presence of pathogenic in ticks () collected from the leopard tortoise () in rural Zambia. Using polymerase chain reaction, 56% (49/87) of ticks were positive for the outer membrane protein () gene.

A Situation Analysis of the Capacity of Laboratories in Faith-Based Hospitals in Zambia to Conduct Surveillance of Antimicrobial Resistance: Opportunities to Improve Diagnostic Stewardship.

Antimicrobial resistance (AMR) is a public health problem exacerbated by the overuse and misuse of antibiotics and the inadequate capacity of laboratories to conduct AMR surveillance. This study assessed the capacity of laboratories in seven faith-based hospitals to conduct AMR testing and surveillance in Zambia. This multi-facility, cross-sectional exploratory study was conducted from February 2024 to April 2024.

Wastewater Surveillance of SARS-CoV-2 in Zambia: An Early Warning Tool.

Wastewater-based surveillance has emerged as an important method for monitoring the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). This study investigated the presence of SARS-CoV-2 in wastewater in Zambia. We conducted a longitudinal study in the Copperbelt and Eastern provinces of Zambia from October 2023 to December 2023 during which 155 wastewater samples were collected.

Stakeholders' Experiences and Preferences Regarding Comprehensive Sexuality Education in Zambia: Implications for Determining Programme Priorities and Strategies.

Background: Understanding and exploring stakeholders' perceptions and preferences regarding comprehensive sexuality education (CSE) is critical in enhancing programme acceptability. We conducted this qualitative study to explore stakeholders' experiences and preferences of CSE in Kitwe district, Zambia.

Methods: We employed a qualitative descriptive design within the interpretive paradigm at nine purposefully selected secondary schools.

Persistent Illegal Hunting of Wildlife in an African Landscape: Insights from a Study in the Luangwa Valley, Zambia.

Decades of illegal hunting (poaching) have adversely affected wildlife populations and thereby limited sustainable wildlife conservation in the Luangwa Valley, Zambia. Despite intervention efforts to address the problem, the illegal hunting of wildlife has persisted. Therefore, this study was conducted to understand the persistence of illegal hunting by investigating the drivers of poaching and intervention measures using a mixed methods approach.

Influence of HIV status on outcomes of children admitted with sepsis at a paediatric hospital in Zambia: protocol for a prospective longitudinal study.

Introduction: Sepsis, a condition of global public health concern, is a major cause of morbidity and mortality, especially in patients with underlying HIV infection. This study aims to determine outcomes, aetiology and antibiotic resistance patterns among children with HIV exposure or infection admitted with a clinical presentation suggestive of sepsis who have confirmed bloodstream infections at Arthur Davison Children's Hospital (ADCH) in Ndola, Zambia.

Methods And Analysis: This will be a prospective longitudinal study of 200 children aged <2 years admitted with sepsis at ADCH with two of the following conditions: temperature of 38.

A review of improvements on electric vehicle battery.

The development of efficient and high-performance electric vehicle (EV) batteries relies on improving various components, such as the anode and cathode electrodes, separators, and electrolytes. This review paper offers an elaborate overview of different materials for these components, emphasizing their respective contributions to the improvement of EV battery performance. Carbon-based materials, metal composites, and polymer nanocomposites are explored for the anode, offering high energy density and capacity.

The Use of Narco SS Score in Predicting Adverse Events in Children Undergoing Major Elective Abdominal Surgery at The University Teaching Hospital, Lusaka, Zambia.

Background: The neurological, airway, respiratory, cardiovascular and other, with a subscore of surgical severity (NARCO-SS) is a scoring system which assesses the presence of systemic disease and the risk the operation poses to the patient. A number of patients that undergo major abdominal surgery suffer adverse events. The aim of the study was to determine the reliability of NARCO-SS in predicting peri-operative adverse events and to determine the risk factors for peri-operative adverse events in paediatric patients undergoing elective abdominal surgery.
