Introduction: Considering the global prevalence of coronavirus disease 2019 (COVID-19), a vaccine is being developed to control the disease as a complementary solution to hygiene measures—and better, in social terms, than social distancing. Given that a vaccine will eventually be produced, informa...tion will be needed to support a potential campaign to promote vaccination.
Objective: The aim of this study was to determine the variables affecting the likelihood of refusal and indecision toward a vaccine against COVID-19 and to determine the acceptance of the vaccine for different scenarios of effectiveness and side effects.
Materials and Methods: A multinomial logistic regression method based on the Health Belief Model was used to estimate the current methodology, using data obtained by an online anonymous survey of 370 respondents in Chile.
Results: The results indicate that 49% of respondents were willing to be vaccinated, with 28% undecided or 77% of individuals who would potentially be willing to be inoculated. The main variables that explained the probability of rejection or indecision were associated with the severity of COVID-19, such as, the side effects and effectiveness of the vaccine; perceived benefits, including immunity, decreased fear of contagion, and the protection of oneself and the environment; action signals, such as, responses from ones' family and the government, available information, and specialists' recommendations; and susceptibility, including the contagion rate per 1,000 inhabitants and relatives with COVID-19, among others. Our analysis of hypothetical vaccine scenarios revealed that individuals preferred less risky vaccines in terms of fewer side effects, rather than effectiveness. Additionally, the variables that explained the indecision toward or rejection of a potential COVID-19 vaccine could be used in designing public health policies.
Conclusions: We discovered that it is necessary to formulate specific, differentiated vaccination-promotion strategies for the anti-vaccine and undecided groups based on the factors that explain the probability of individuals refusing or expressing hesitation toward vaccination.

Monkeypox is an emerging viral zoonosis with symptoms similar to those observed in smallpox patients, although less severe. Since the global eradication of smallpox in 1980, monkeypox has emerged as the most important orthopoxvirus in humans. The Advisory Committee on Variola Virus Research (ACVVR) ...which meets annually to oversee smallpox research has highlighted the importance of diagnostics that could distinguish between variola and other strains of orthopoxviruses, including monkeypox virus. The ACVVR encourages the positive effects of current smallpox research on all orthopoxviruses, specifically monkeypox, such as the development of diagnostic tools.

This is the seventeenth annual publication of the Global Hunger Index (GHI), a report jointly published by Concern Worldwide and Welthungerhilfe.
The 2022 Global Hunger Index (GHI) brings us face to face with a grim reality. The toxic cocktail of conflict, climate change, and the COVID-19 pandemi...c had already left millions exposed to food price shocks and vulnerable to further crises. Now the conflict in Ukraine—with its knock-on effects on global supplies of and prices for food, fertilizer, and fuel—is turning a crisis into a catastrophe. But the speed and severity of the global food crisis reflects the fact that millions of people were already living on the precarious edge of hunger—a legacy of past failures to build more just, sustainable, and resilient food systems. This year’s report therefore focuses on food systems transformation and local governance.
According to the 2022 GHI, Hunger is at alarming levels in 5 countries—Central African Republic, Chad, Democratic Republic of the Congo, Madagascar, and Yemen— and is provisionally considered *alarming *in 4 additional countries— Burundi, Somalia, South Sudan, and Syria. In a further 35 countries, hunger is considered serious, based on 2022 GHI scores and provisional designations.

Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is lim...ited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are... limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.

This document focus on the direct consequences of the virus (morbidity and mortality) in specific populations and on the results of measures aimed at mitigating the spread of the virus, with indirect impacts on socio-economic conditions. In this complex scenario, the gender approach has not received... due attention during the pandemic. Gender is one of the structural determinants of health, but it does not appear in analyses of the direct and indirect effects of the pandemic, despite being essential in the recognition and analysis of the differential impacts on men and women and their interaction with the different determinants of health.

The Arab region in the Middle East and North Africa (MENA) represents a substantial area of the terrestrial landmass encompassing several countries and ecosystems. This area is generally drier and warmer compared to the rest of the world and has extreme resource limitations that are highly vulnerabl...e to a changing climate, geopolitical instability and land degradation (Slimani & Aidoud, 2004). Agriculture (crops and livestock) is a critical source of employment and a potential option for engaging rural youth. However, environmental degradation coupled with declining and variable agricultural productivity may pose a massive challenge already beset by instability and declining oil reserves (Tagliapietra, 2017). The Arab region is also subjected to short and long-duration climate extreme events, and the overall impact of their cascading effects on ecosystems, societies and economies is still an open question. Climate change, along with post-war geopolitical complexities, has greatly affected the Arab region in terms of its economy and social balance. Climate change has penetrating effects on the region’s agriculture sector and hence its economy. These are mainly manifested via changes in water resources and extreme weather conditions such as heatwaves and a drastic decline in precipitation.

This fourth annual report monitors global progress towards the 2023 target for global elimination of industrially produced trans-fatty acids (TFA), highlighting achievements during the past year (October 2021 – September 2022). Countries are responding to the World Health Organization (WHO) call t...o action by putting into place best-practice TFA policies. Mandatory TFA policies are currently in effect for 3.4 billion people in 60 countries (43% of the world population); of these, 43 countries have best-practice policies in effect, covering 2.8 billion people (36% of the world population).
Over the past year, several additional countries took action to eliminate industrially produced TFA: best-practice policies came into effect in India in January 2022, Uruguay in May 2022 and Oman in July 2022. Best-practice policies were passed in Bangladesh in November 2021 (to come into effect in December 2022) and in Ukraine in September 2020 (to come into effect in October 2023), best-practice TFA policies are projected to pass soon in Mexico, Nigeria and Sri Lanka.

Leishmaniasis is a climate-sensitive disease. Changes in temperature, rainfall, and humidity can have strong impacts on
the sandfly vector, altering their distribution and influencing their survival and population sizes. Increased temperatures shorten vector development time, reduce Leishmania para...site incubation time, and increase vector biting rates, allowing transmission
in areas not previously endemic for the disease. Poor and
marginalized communities will be hit disproportionately harder by
the effects of climate change, and droughts, famines, and floods
can also lead to displacement and migration of immunologically
naive people to areas where leishmaniasis is endemic, posing a
threat of leishmaniasis outbreaks.

We reviewed the evidence on community-based interventions for the prevention and control of cutaneous leishmaniasis (CL). Community initiatives tailored towards awareness and mobilisation are regarded as a priority area in the Neglected Tropical Disease Roadmap 2021–2030 by the World Health Organi...zation. We searched nine electronic databases for intervention-based
studies. Two independent reviewers screened and assessed the articles for methodological quality using predefined criteria. We conducted a meta-analysis using a random effects model, along with narrative synthesis. Thirteen articles were eligible for inclusion, of which 12 were quantitative studies (quasi-experimental with control group and pre-post interventions) and one qualitative
study. All articles reported on health education interventions aimed at changing people’s knowledge, attitudes, and practices (KAP) in relation to CL. Participant groups included students, mothers, housewives, volunteer health workers, and residents in general. An increased score was recorded for all outcomes across all interventions: knowledge (SMD: 1.85, 95% CI: 1.23, 2.47), attitudes (SMD:
1.36, 95% CI: 0.56, 2.15), and practices (SMD: 1.73, 95% CI: 0.99, 2.47). Whilst our findings show that educational interventions improved people’s knowledge, attitudes, and practices about CL, we argue that this approach is not sufficient for the prevention and control of this disease. Knowledge does not always translate into action, particularly where other structural barriers exist. Therefore,
we recommend the design of more innovative community-based interventions with a broader focus (e.g., stigma, financial barriers, and healthcare access).

Food is one of the most traded goods, and the conflict in Ukraine, one of the European breadbaskets, has triggered a significant additional disruption in the global food supply chains after the COVID-19 impact. The disruption to food output, supply chains, availability, and affordability could have ...a long-standing impact. As a result, the availability and supply of a wide range of food raw materials and finished food products are under threat, and global markets have seen recent increases in food prices. Furthermore, the Russian-Ukrainian conflict has adversely affected food supply chains, with significant effects on production, sourcing, manufacturing, processing, logistics, and significant shifts in demand between nations reliant on imports from Ukraine.

Cutaneous leishmaniasis (CL) is a parasitic disease caused by infection with a vector-borne protozoan parasite of the genus Leishmania spp. The parasite is transmitted by the bite of an infected phlebotomine sand fly. Infection results in skin lesions which take a long time to heal and may leave per...manent, disfiguring scars (de Vries et al. 2015). CL is classified as a neglected tropical disease (NTD), and in common with several other NTDs, is associated with psychosocial effects including stigma, social exclusion, and declining mental health (Bailey et al. 2019; Bennis et al. 2018; Wenning et al. 2022). Emerging evidence suggests that people with CL are at a higher risk of experiencing anxiety, depression, decreased body satisfaction, loss of social status, and lower quality of life (Bennis et al. 2018; Yanik et al. 2004). The global mean age-standardised disability-adjusted life years (DALYs) lost by CL was 0.58 per 100,000 people (Karimkhani et al. 2016). Notably, this statistic only considers the physical effects of the lesions and does not account for the potentially considerable psychological and social effects of CL (Bailey et al. 2017; Bailey et al. 2019; Wenning et al. 2022).

Today, patient harm due to unsafe care is a large and growing global public health challenge and is one of the
leading causes of death and disability worldwide. Most of this patient harm is avoidable. As countries strive to
achieve universal health coverage and the Sustainable Development Goals, t...he beneficial effects of improved
access to health services can be undermined by unsafe care. Patient safety incidents can cause death and
disability, and suffering for victims and their families. The financial and economic costs of safety lapses are high.
There is often reduced public confidence and trust in local health systems when such incidents are publicized.
Health workers involved in serious incidents involving death or serious harm to a patient can also suffer lasting
psychological harm and deep-seated feelings of guilt and self-criticism.

Forests, trees and green spaces, hereinafter ‘forests and trees’ for short, provide multiple goods and services that contribute to human health. These include medicines, nutritious foods and other non-wood forest products (NWFPs). Globally, at least 3.5 billion people use NWFPs, including medici...nal plants, which are particularly important for vulnerable groups and Indigenous Peoples and local communities (IPLCs).
During periods of crises, such as the COVID-19 pandemic, demand for forest products typically increases amongst these groups. Forests and trees also contribute to better health by playing a role in climate change
mitigation and adaptation, contributing to regulating the carbon cycle, but also moderating the micro-climate, filtering pollutants from the air and protecting settlements against the effects of extreme events such as droughts and flash floods.

This publication describes the first WHO public-benefit Target Product Profiles (TPPs) for snakebite antivenoms. It focuses on antivenoms for treatment of snakebite envenoming in sub-Saharan Africa. Four TPPs are described in the document:
Broad spectrum Pan-African polyvalent antivenoms: products ...that are intended for widespread utility throughout sub-Saharan Africa for treatment of envenoming irrespective of the species of snake causing a bite. Monovalent antivenoms for specific use cases: for products for a single species (or genus) of snake (e.g., boomslangs or carpet viper antivenoms).
Syndromic Pan-African polyvalent antivenoms for neurotoxic envenoming: products that are intended for treatment of envenoming by species whose venoms are neurotoxic. Syndromic Pan-African polyvalent antivenoms for non-neurotoxic envenoming: products for snakebite envenoming where the effects are largely haemorrhagic, necrotic or procoagulant.

The greatest risk to persons engaging in international medical emergency response is poor preparation.
The In Control handbook hopes to provide a remedy.
At the time of writing, we are living through the Coronavirus (COVID-19) pandemic, a health emergency that disregards physical borders, brin...gs into focus social inequalities and affects people on every continent. This shared challenge requires unprecedented measures and the collaboration of the brightest minds to support global health protection through this crisis and beyond. Healthcare infrastructures have to be strengthened, public health capacities and processes upgraded, medical countermeasures and vaccinations found and psychosocial side-effects treated.
Solidarity is the normative order of the day and the human species has to collaborate to face this invisible threat. Hiding and living in fear is not an option in this interconnected world. We have both a responsibility and an opportunity to make substantial contributions to a safer, healthier and more sustainable future for us all.
The existence of this handbook is an impressive example of solidarity. Over 50 authors from more than 15 institutes and organisations have come together voluntarily within a very short time to make their expertise available and enable cross-sectoral thinking. Knowledge is bundled, resources are combined, information gaps are filled. The In Control handbook is not a theoretical treatise of possible dangers, but a collection of subject-matter expertise, written by experts and practitioners who have shaped health topics over the past 20 years in the most diverse corners of the world.
The Centre for International Health Protection at the Robert Koch Institute (RKI) is collaborating with its partners and investing heavily in the build-up of operational know-how and capacity to support health crisis response abroad. This is done by preparing and enabling professionals to deploy safely across the world to assist those in need. In Control addresses the multi-faceted challenges of an international deployment. Readers will find not only technical medical information, but also insights into, for example, the fragility of our environment, the cultural differences that influence risk communication or the dilemmas arising from social distancing. Legal principles are highlighted, along with ethical guidance to ensure that our actions and decisions correspond to the highest moral standards.

Background
The ambitious development agenda of the Sustainable Development Goals (SDGs) requires substantial investments across several sectors, including for SDG 3 (healthy lives and wellbeing). No estimates of the additional resources needed to strengthen comprehensive health service delivery to...wards the attainment of SDG 3 and universal health coverage in low-income and middle-income countries have been published.
Methods
We developed a framework for health systems strengthening, within which population-level and individual-level health service coverage is gradually scaled up over time. We developed projections for 67 low-income and middle-income countries from 2016 to 2030, representing 95% of the total population in low-income and middle-income countries. We considered four service delivery platforms, and modelled two scenarios with differing levels of ambition: a progress scenario, in which countries’ advancement towards global targets is constrained by their health system’s assumed absorptive capacity, and an ambitious scenario, in which most countries attain the global targets. We estimated the associated costs and health effects, including reduced prevalence of illness, lives saved, and increases in life expectancy. We projected available funding by country and year, taking into account economic growth and anticipated allocation towards the health sector, to allow for an analysis of affordability and financial sustainability.

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.”
