Antibody testing can determine previous exposure to SARS-CoV-2 virus. Recently, the UK government has made antibody testing available to anyone wanting it, even if there is no clinical indication. The purpose of this article is to provide guidance for when to consider antibody testing in individuals with and without symptoms suggestive of current or past SARS-CoV-2 infection. Key points made by the authors include: (1) antibody testing is likely to be most useful 2 weeks…

EditorialPublication 2020Waiting for Certainty on COVID-19 Antibody Tests — At What Cost?
This perspective anticipates the availability of serologic antibody testing and considers its potential usefulness in mitigation …
This perspective anticipates the availability of serologic antibody testing and considers its potential usefulness in mitigation policy to reduce COVID-19 transmission. For example: Could we screen for serologic antibodies as a proxy for possible immunity and identify people who could return to the workplace with less severe mitigation measures? The authors acknowledge the uncertainties raised by many policy actors, including the WHO, such as, "Do antibodies confer immunity and, if so, for how long? How accurate is…

ArticlePublication 2020Bayes' Theorem, COVID-19, and Screening Tests
This article reviews the implications of increased testing for COVID-19 using reverse transcriptase polymerase chain …
This article reviews the implications of increased testing for COVID-19 using reverse transcriptase polymerase chain reaction (rRT-PCR) through the application of Bayes’ Theorem for three hypothetical, stylized case scenarios. The scenarios involve three patients with a low, moderate, and high pre-test probability of COVID-19 infection. The category of low probability would include "asymptomatic individuals in a presumed low prevalence environment" and might vary from 10 to 20%. The category of moderate probability would include "individuals…

ArticlePublication 2020Interpreting COVID-19 Test Results: A Bayesian Approach
This article considers the following question with respect to interpreting the results of polymerase chain reaction …
This article considers the following question with respect to interpreting the results of polymerase chain reaction (PCR) assays from nasal and pharyngeal swabs for COVID-19 to inform clinical decision making: "While a positive result in an acutely ill patient is straightforward, how should physicians interpret negative tests in patients with suspected COVID-19 infection?" Using an assumption of near-perfect specificity of PCR assays for COVID-19, the authors acknowledge the uncertainty of test sensitivity. They consider two clinical scenarios…

ArticlePublication 2020Health Gains & Financial Risk Protection Afforded by Public Financing of Selected Malaria Interventions in Ethiopia: An ECEA
This article, published in the Malaria Journal, aims to estimate the expected health and financial …
This article, published in the Malaria Journal, aims to estimate the expected health and financial risk protection (FRP) benefits of universal public financing of key malaria interventions in Ethiopia. An extended cost-effectiveness analysis (ECEA) is used to estimate the potential health and FRP benefits of publicly financing a 10% increase in artemisinin-based combination therapy (ACT), long-lasting insecticide-treated bed nets (LLIN), indoor residual spraying (IRS), and a hypothetical malaria vaccine. The results indicate that ACT, LLIN,…

Extended cost-effectiveness analyses (ECEAs) build on cost-effectiveness analyses (CEAs) by assessing consequences in both the health and non-health domains. The ECEA approach proves novel in that it includes equity and non-health benefits (FRP) in the economic evaluation of health policies, which enables multiple criteria to factor in the decision-making process. More important, the ECEA approach enables the design of benefits packages, such as essential universal health care and the highest-priority package, based on the quantitative…

ReportPublication 2017DCP3: Injury Prevention and Environmental Health
This report from the World Bank is the seventh volume of the Disease Control Priorities, …
This report from the World Bank is the seventh volume of the Disease Control Priorities, Third Edition (DCP3) series and focuses on injury prevention and environmental health. The burden of death and disability resulting from interpersonal violence, road traffic injuries, unintentional injuries, occupational health risks, and climate and pollution falls disproportionately on low- and middle- income countries. This report examines risk factors and offers an economic analysis of platforms to deliver cost-effective interventions to prevent…

This report from the World Bank is the eighth volume of the Disease Control Priorities, …
This report from the World Bank is the eighth volume of the Disease Control Priorities, Third Edition (DCP3) series and focuses on the health and well-being of children and adolescents, ages 5 to 21, worldwide. It provides estimates of mortality and morbidity among youth, examines the impact of interventions during that period on health and development, features successful community- and school-based health and nutrition interventions, reports on platforms that promote early childhood development, and highlights…

ReportPublication 2017DCP3: Cardiovascular, Respiratory, and Related Disorders
This report from the World Bank is the fifth volume of the Disease Control Priorities, …
This report from the World Bank is the fifth volume of the Disease Control Priorities, Third Edition (DCP3) series. It addresses the disease burden of cardiovascular, respiratory, and related disorders (CVRDs), which account for more than half of global adult deaths, mostly in low- and middle-income countries. While CVRDs are mostly preventable or can be treated to reduce morbidity, such interventions are costly and require greater capacity to detect and treat early. When combined with…
