Future developments in the prevention, diagnosis and treatment of COVID-19

The impact of the coronavirus disease-2019 (COVID-19) pandemic has been profound and global. Mitigating future waves and overcoming the pandemic is a global public health priority. This review focuses on future developments in the prevention, diagnosis and treatment of COVID-19, which may help to address these challenges. The specific relevance to women's and maternal health, which address the vulnerabilities in this group, is considered. The remarkable scientific achievements that have been made with respect to the development and implementation of both vaccines and therapeutics for COVID-19 are highlighted. The speed and processes for the development, approval and implementation of interventions herald a new way forward in combating emerging infectious diseases. However, it is important to note that this is a rapidly changing field with a constantly evolving knowledge base

National cross-sectional survey of 1.14 million NHS staff SARS-CoV-2 serology tests: a comparison of NHS staff with regional community seroconversion rates

OBJECTIVES: An initial report of findings from 1.14 million SARS CoV-2 serology tests in National Health Service (NHS) staff to compare NHS staff seroconversion with community seroconversion rates at a regional level. DESIGN: A national cross-sectional survey. SETTING: A SARS-CoV-2 antibody testing programme offered across all NHS Trusts. PARTICIPANTS: 1.14 million NHS staff. INTERVENTION: SARS-CoV-2 antibody testing. PRIMARY AND SECONDARY OUTCOME MEASURES: SARS-CoV-2 antibody testing was used to estimate the seroprevalence of SARS-CoV-2 in NHS staff by region, compared with community seroprevalence as determined by the COVID-19 Infection Survey (Office for National Statistics). We also explored seroprevalence trends by regional COVID-19 activity, using regional death rates as a proxy for COVID-19 'activity'. RESULTS: 1 146 310 tests were undertaken on NHS staff between 26 May and 31 August 2020. 186 897 NHS tests were positive giving a seroconversion rate of 16.3% (95% CI 16.2% to 16.4%), in contrast to the national community seroconversion rate of 5.9% (95% CI 5.3% to 6.6%). There was significant geographical regional variation, which mirrored the trends seen in community prevalence rates. NHS staff were infected at a higher rate than the general population (OR 3.1, 95% CI 2.8 to 3.5). NHS seroconversion by regional death rate suggested a trend towards higher seroconversion rates in the areas with higher COVID-19 'activity'. CONCLUSIONS: This is the first cross-sectional survey assessing the risk of COVID-19 disease in healthcare workers at a national level. It is the largest study of its kind. It suggests that NHS staff have a significantly higher rate of COVID-19 seroconversion compared with the general population in England, with regional variation across the country which matches the background population prevalence trends. There was also a trend towards higher seroconversion rates in areas which had experienced high COVID-19 clinical activity. This work has global significance in terms of the value of such a testing programme and contributing to the understanding of healthcare worker seroconversion at a national level

The Ebola outbreak, 2013-2016: old lessons for new epidemics

Ebola virus causes a severe haemorrhagic fever in humans with high case fatality and significant epidemic potential. The 2013–2016 outbreak in West Africa was unprecedented in scale, being larger than all previous outbreaks combined, with 28 646 reported cases and 11 323 reported deaths. It was also unique in its geographical distribution and multicountry spread. It is vital that the lessons learned from the world's largest Ebola outbreak are not lost. This article aims to provide a detailed description of the evolution of the outbreak. We contextualize this outbreak in relation to previous Ebola outbreaks and outline the theories regarding its origins and emergence. The outbreak is described by country, in chronological order, including epidemiological parameters and implementation of outbreak containment strategies. We then summarize the factors that led to rapid and extensive propagation, as well as highlight the key successes, failures and lessons learned from this outbreak and the response

Barriers to maternal health services during the Ebola outbreak in three West African countries: a literature review

Introduction The Ebola virus disease (EVD) outbreak in West Africa, affecting Guinea, Liberia and Sierra Leone from 2014 to 2016, was a substantial public health crisis with health impacts extending past EVD itself. Access to maternal health services (MHS) was disrupted during the epidemic, with reductions in antenatal care, facility-based deliveries and postnatal care. We aimed to identify and describe barriers related to the uptake and provision of MHS during the 2014–2016 EVD outbreak in West Africa. Methods In June 2020, we conducted a scoping review of peer-reviewed publications and grey literature from relevant stakeholder organisations. Search terms were generated to identify literature that explained underlying access barriers to MHS. Published literature in scientific journals was first searched and extracted from PubMed and Web of Science databases for the period between 1 January 2014 and 27 June 2020. We hand-searched relevant stakeholder websites. A ‘snowball’ approach was used to identify relevant sources uncaptured in the systematic search. The identified literature was examined to synthesise themes using an existing framework. Results Nineteen papers were included, with 26 barriers to MHS uptake and provision identified. Three themes emerged: (1) fear and mistrust, (2) health system and service constraints, and (3) poor communication. Our analysis of the literature indicates that fear, experienced by both service users and providers, was the most recurring barrier to MHS. Constrained health systems negatively impacted MHS on the supply side. Poor communication and inadequately coordinated training efforts disallowed competent provision of MHS. Conclusions Barriers to accessing MHS during the EVD outbreak in West Africa were influenced by complex but inter-related factors at the individual, interpersonal, health system and international level. Future responses to EVD outbreaks need to address underlying reasons for fear and mistrust between patients and providers, and ensure MHS are adequately equipped both routinely and during crises

From the micro to the macro to improve health: microorganism ecology and society in teaching infectious disease epidemiology

Chronic and emerging infectious diseases and antimicrobial resistance remain a substantial global health threat. Microbiota are increasingly recognised to play an important role in health. Infections also have a profound effect beyond health, especially on global and local economies. To maximise health improvements, the field of infectious disease epidemiology needs to derive learning from ecology and traditional epidemiology. New methodologies and tools are transforming understanding of these systems, from a better understanding of socioeconomic, environmental, and cultural drivers of infection, to improved methods to detect microorganisms, describe the immunome, and understand the role of human microbiota. However, exploiting the potential of novel methods to improve global health remains elusive. We argue that to exploit these advances a shift is required in the teaching of infectious disease epidemiology to ensure that students are well versed in a breadth of disciplines, while maintaining core epidemiological skills. We discuss the following key points using a series of teaching vignettes: (1) integrated training in classic and novel techniques is needed to develop future scientists and professionals who can work from the micro (interactions between pathogens, their cohabiting microbiota, and the host at a molecular and cellular level), with the meso (the affected communities), and to the macro (wider contextual drivers of disease); (2) teach students to use a team-science multidisciplinary approach to effectively integrate biological, clinical, epidemiological, and social tools into public health; and (3) develop the intellectual skills to critically engage with emerging technologies and resolve evolving ethical dilemmas. Finally, students should appreciate that the voices of communities affected by infection need to be kept at the heart of their work

Untangling approaches to management and leadership across systems of medical education

Aims: How future doctors might be educated and trained in order to meet the population and system needs of countries is currently being debated. Incorporation of a broad range of capabilities, encompassed within categories of management and, increasingly, leadership, form part of this discussion. The purpose of this paper is to outline a framework by which countries’ progress in this area might be assessed and compared. Methods: Key databases and journals related to this area were reviewed. From relevant articles potential factors impacting on the incorporation of aspects of management and leadership within medical education and training were identified. These factors were tested via an online survey during 2013 with six members of a European Association of doctors who promote medical involvement in hospital management, including members from countries less represented in the health management literature. Results: A framework for analysing how management and leadership education is being approached within different systems of healthcare is developed and presented. Conclusions: More systematic work across a wider range of countries is needed if we are to have a better understanding of how countries within and beyond Europe are approaching and progressing the education of doctors in management and leadership.
