The ICAT is a simple and practical approach for assessing the adequacy of existing infection prevention and control practices and provides specific recommendations for improving practices and monitoring their effectiveness over time
A total of 18 laboratories from 13 countries participated in the four rounds of EQA: 10 laboratories from eight African endemic countries, four of which participated in all four rounds and three in three rounds. The overall results showed that the median performance of these laboratories improved ov...er the four rounds. However, the proportion of laboratories reporting false–positive cases remains high and indicates a problem of specificity probably due to contamination. The proportion of laboratories reporting both false–positive and false–negative results raises the issue of the quality of the data reported by WHO in Africa as well as the results of the studies carried out in these different laboratories in various countries.

Since the release of the first volume in May 2020, the COVID-19 pandemic has continued to rage around the world. By mid-March, 2021, countries around the globe had reported over 123 million cases—a nearly five-fold increase since this report’s previous volume—and over 2.7 million deaths attrib...uted to the disease. And while new case loads are currently on the rise again, the global health community has already administered almost 400 million doses of vaccines, at last offering some signs of hope and progress.
Economic impacts threaten to undo decades of recent progress in poverty reduction, child nutrition and gender equality, and exacerbate efforts to support refugees, migrants, and other vulnerable communities. National and local governments—together with international and private-sector partners—must deploy vaccines as efficiently, safely and equitably as possible while still monitoring for new outbreaks and continuing policies to protect those who do not yet have immunity.
More than ever, the world needs reliable and trustworthy data and statistics to inform these important decisions. The United Nations and all member organizations of the Committee for the Coordination of Statistical Activities (CCSA) collect and make available a wealth of information for assessing the multifaceted impacts of the pandemic. This report updates some of the global and regional trends presented in Volume I and offers a snapshot of how COVID-19 continues to affect the world today across multiple domains.

WHO has developed a clinical case definition of post COVID-19 condition by Delphi methodology that includes 12 domains, available for use in all settings. This first version was developed by patients, researchers and others, representing all WHO regions, with the understanding that the definition ma...y change as new evidence emerges and our understanding of the consequences of COVID-19 continues to evolve.
Post COVID-19 condition occurs in individuals with a history of probable or confirmed SARS CoV-2 infection, usually 3 months from the onset of COVID-19 with symptoms and that last for at least 2 months and cannot be explained by an alternative diagnosis. Common symptoms include fatigue, shortness of breath, cognitive dysfunction but also others and generally have an impact on everyday functioning. Symptoms may be new onset following initial recovery from an acute COVID-19 episode or persist from the initial illness. Symptoms may also fluctuate or relapse over time.

The climate crisis has many consequences – among them widespread health impacts that will lead to immense societal, ecological, and economic harm.
Over the past two decades multiple large-scale reviews on climate change and health have made clear the need for a multi-sectoral approach to target t...he drivers and impacts of climate change, biodiversity loss, and ecosystem degradation. Despite this abundance of scientific evidence underscoring urgency of action, policy implementation responses lag behind. Even at COP26, itself delayed due to an ongoing pandemic, health continues to be considered by many countries a problem independent from climate and environment.

The Lancet Planetary Health Volume 6, ISSUE 4, e342-e349, April 01, 2022. Human impacts on earth-system processes are overshooting several planetary boundaries, driving a crisis of ecological breakdown. This crisis is being caused in large part by global resource extraction, which has increased dra...matically over the past half century. We propose a novel method for quantifying national responsibility for ecological breakdown by assessing nations’ cumulative material use in excess of equitable and sustainable boundaries.

Three classess of tests are now recommended in the latest consolidated guideles on tests for tuberculosis infection. It includes for the first-time a new class of Mycobacterium tuberculosis antigen-based skin tests (TBSTs), and the two existing classes of tests: the tuberculin skin test (TST) and t...he interferon-gamma release assays (IGRAs).
IGRAs and TBSTs use Mycobacterium tuberculosis complex specific antigens and represent a significant advancement to TST which has been used for over half a century.

Worldwide, over 6 million people are infected with Trypanosoma cruzi, the pathogen that causes Chagas disease (CD). In the Americas, CD creates the greatest burden in disability-adjusted life years of any parasitic infection. In Co...lombia, 437 000 people are infected with T. cruzi, of whom 131 000 suffer from cardiomyopathy. Colombia’s annual costs for treating patients with advanced CD reach US$ 175 016 000. Although timely etiological treatment can significantly delay or prevent development of cardiomyopathy—and costs just US$ 30 per patient—fewer than 1% of people with CD in Colombia and elsewhere receive it.

Chagas disease is currently endemic and also predicted to be at increased transmission risk under future climate change scenarios. Similarly, an expansion of areas in the United States at increased risk for Chagas disease transmission is also expected over the next several decades under climate chan...ge scenarios. Of particular interest is the predicted northern shift of triatomine species to central regions of the United States with historically unsuitable climates for T. cruzi vectors. The weight of evidence regarding the influences climate change may pose on T. cruzi vector species distributions demonstrates the sensitivity of Chagas disease transmission to future climate variability. In order to advance forecasts for the impact climate change may have on Chagas disease transmission in the Americas, it is imperative to
further develop, utilize, and perhaps combine predictive species distribution modeling approaches that integrate accurate, long term data on climate variables, vector species distributions, Chagas disease incidence, as well as other socio-ecological variables.

This paper introduces a new dataset of official financing—including foreign aid and other forms of concessional and non-concessional state financing—from China to 138 countries between 2000 and 2014. We use these data to investigate whether and to what extent Chinese aid affects economic growth ...in recipient countries. To account for the endogeneity of aid, we employ an instrumental-variables strategy that relies on exogenous variation in the supply of Chinese aid over time resulting from changes in Chinese steel production. Variation across recipient countries results from a country’s probability of receiving aid. Controlling for year- and recipient-fixed effects that capture the levels of these variables, their interaction provides a powerful and excludable instrument. Our results show that Chinese official development assistance (ODA) boosts economic growth in recipient countries. For the average recipient country, we estimate that one additional Chinese ODA project produces a 0.7 percentage point increase in economic growth two years after the project is committed. We also benchmark the effectiveness of Chinese aid vis-á-vis the World Bank, the United States, and all members of the OECD’s Development Assistance Committee (DAC).

Little is known about foreign aid provided by private donors. This paper contributes to closing this research gap by comparing the allocation of private humanitarian aid to that of official humanitarian aid awarded to 140 recipient countries over the 2000-2016 period. We construct a new database tha...t offers information on the country in which the headquarters of private donors are located to test whether private donors follow the aid allocation pattern of their home country. Our empirical results confirm that private aid “follows the flag.” This finding is robust against the inclusion of various fixed effects, estimating instrumental variables models, and disaggregating private aid into corporate aid and NGO aid. Donor country-specific estimations reveal that private aid from China, Sweden, the United Kingdom, and the United States “follow the flag.”

Climate change is one of the most urgent challenges for people and ecosystems worldwide. The recently published sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change (IPCC) stresses the occurrence of widespread adverse impacts of climate change. Increased frequency and inten...sity of extreme weather events, as well as slow-onset processes cause enormous losses and damages to human and natural systems. Marginalized groups and people in vulnerable situations are often disproportionally affected. While the impacts of climate change already become more tangible and threatening, action for addressing them remains insufficient. Adaptation to climate change is, thus, becoming a necessity for governments, companies, and private citizens.
To provide practical and scientifically sound guidance on how to conduct vulnerability assessments, GIZ published its Vulnerability Sourcebook in 2014. The Vulnerability Sourcebook was used in over twenty different GIZ partner countries and provides a step-by-step guidance for designing and implementing a vulnerability assessment. It is also one of the methodological foundations for the ISO 14091:2021 standard on vulnerability, impacts and risk assessment for climate change adaptation.

Asthma is the most common chronic respiratory disease (CRD) worldwide and is estimated to affect 262 million causing significant mortality and morbidity, and has emerged as an important public health problem in many Latin American (LA) countries over the last 30 or so years. LA is a highly diverse r...egion in terms of geography, climate, wealth, and ethnicity including 20 different countries with 639 million inhabitants, where 40 million are estimated to have asthma. A common feature of LA countries is the high level of social inequalities3 (Figure 1). In LA, asthma prevalence in both children and adults is highly variable and, where high, is among the highest worldwide, particularly in coastal tropical cities.
