Dengue is a mosquito-borne viral disease that has rapidly spread to all regions of WHO in recent years. Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae. albopictus. These mosquitoes are also vectors of chikungunya, yellow fever and Zik...a viruses. Dengue is widespread throughout the tropics, with local variations in risk influenced by climate parameters as well as social and environmental factors.

AACAP OFFICIAL ACTION | This Practice Parameter identifies best approaches to the assessment and management of children and adolescents across all phases of a disaster. Delivered within a disaster system of care, many interventions are appropriate for implementation in the weeks and months after a d...isaster. These include psychological first aid, family outreach, psychoeducation, social support, screening, and anxiety reduction techniques. The clinician should assess and monitor risk and protective factors across all phases of a disaster. Schools are a natural site for conducting assessments and delivering services to children. Multimodal approaches using social support, psychoeducation, and cognitive behavioral techniques have the strongest evidence base. Psychopharmacologic interventions are not generally used but may be necessary as an adjunct to other interventions for children with severe reactions or coexisting psychiatric conditions

In recent years Terre des Hommes Netherlands observed the steady rise of a new form of child sexual exploitation. One that is enabled and fuelled by rapid technological advances, increasing global connectivity, persisting poverty rates, and growing disparity in the global distribution of resources. ...Terre des Hommes Netherlands received alarming signals from collaborating project partners from the Philippines that new commercial child exploitation trades are evolving and spreading parallel to rising global Internet access rates and developments in communications technology.
Webcam child sex tourism is evidently growing, closely related to child prostitution, child trafficking and child abuse. What is not clear however, are the psychological and social consequences of this new phenomenon. To date, no research has been done on the psychosocial consequences of webcam sex for children. The aim of this research is therefore to gain more knowledge on the psychosocial consequences of webcam child sex tourism for children and to give insight into the antecedent factors that play a role.

This report serves as a background paper to five short studies Yemeni-international researcher tandems will jointly develop in the course of 2019. It places a particular focus on ‘peace requirements’, a term that seeks to draw attention to the manifold challenges to establishing stab...ility and building peace in Yemen and the resulting efforts which will be required. This report analyzes the current situation in Yemen by looking at social structures, current conflict dynamics, the role and situation of state institutions and external factors, and then moves on to focus on what is required to build peace in Yemen. In laying out these peace requirements, the report focuses on the following relevant sectors: economy, politics, culture and society, as well as security and justice. In a last step, it takes a look at the challenges to and capacities of five different actor groups in Yemen to address these needs: civil society, women, youth, the media and the private sector

COVID-19 Vaccines: 1 Safety Surveillance 2 Manual
While there is no indication that pregnant women have an increased susceptibility to infection with SARS-CoV-2, there is evidence that pregnancy may increase the risk of severe illness and mortality from COVID-19 disease in comparison with non-pregn...ant women of reproductive age. As seen with non-pregnant women, a high proportion of pregnant women have asymptomatic SARS-CoV-2 infection and severe disease is associated with recognized medical (e.g., high body-mass index (BMI), diabetes, pre-existing pulmonary or cardiac conditions) and social (e.g., social deprivation, ethnicity) risk factors. Pregnant women with symptomatic COVID-19 appear to have an increased risk of intensive care unit admission, mechanical ventilation and death in comparison with non-pregnant women of reproductive age, although the absolute risks remain low. COVID-19 may increase the risk of preterm birth, compared with pregnant women without COVID-19, although the evidence is inconclusive.

People on the move – migrants, refugees, asylum seekers and other displaced populations – face extraordinary risks to their lives, safety, dignity, human rights and well-being.
In part this is connected to the core reasons that lead to migration and displacement, ranging from violence, persec...ution, conflict, poverty, political and social issues, as well as disasters and the adverse effects of climate change. In 2021, we are seeing the compounding factors of the COVID-19 pandemic and the climate crisis driving higher numbers of people to migrate, exacerbating risks and vulnerabilities.

Climate change, increasing population densities, and intensified globalisation in trade, travel and migration are among the most important factors shaping the 21st century. Each impacts upon population health and the risk of infectious disease, particularly those originating at the human-animal-envi...ronmental interface. The recognition that many risk drivers of infectious disease fall outside of the typical domain of the health sector creates the challenge of identifying and pursuing priorities for cross-sectoral action aimed at strengthening global health security. In response, the One Health concept has emerged, as have related initiatives addressing Planetary Health and Biodiversity and Human Health. From a public health perspective and operationally speaking, the One Health approach offers great potential, emphasising as it does cooperation and coordination between multiple sectors. Yet despite having been a focal point for discussion for over a decade, numerous challenges facing the implementation of One Health preparedness strategies remain. While some are technical, related to the requirement for innovative early warning systems or new vaccines, for example, others are institutional and cultural in nature, given the transdisciplinary nature of the topic. There have thus been calls to address One Health from multiple perspectives, from ecology to the social sciences. In order to further explore this issue and to identify priority areas for action for strengthening One Health preparedness in Europe, ECDC convened an expert consultation on 11–12 December 2017.

Ethnic disparities in COVID-19 persist, with increased rates of infection, severe disease, and death among people from minority ethnic groups. COVID-19 vaccination rates also remain lowest in these communities compared with white people in the UK. Among people older than 18 years, the proportion who... have had three COVID-19 vaccinations in England in March, 2022, was lowest among Black Caribbean (38%), Black African (45%), and Pakistani (45%) ethnic groups. These disparities are likely to be attributed to the intersection of key social determinants, including socioeconomic factors such as deprivation, overcrowding, and working patterns and conditions,
alongside discrimination and structural violence in the health-care system and society.

The United Nations Children's Fund (UNICEF), the International Organization for Migration (IOM), Georgetown University, and the United Nations University have today launched new guidelines to provide the first-ever global policy framework that will help protect, include, and empower children on the ...move in the context of climate change.
The Guiding Principles for Children on the Move in the Context of Climate Change provides a set of 9 principles that address the unique and layered vulnerabilities of children on the move both internally and across borders as a result of the adverse impacts of climate change. Currently, most child-related migration policies do not consider climate and environmental factors, while most climate change policies overlook the unique needs of children.
The guidelines note that climate change is intersecting with existing environmental, social, political, economic, and demographic conditions contributing to people’s decisions to move. In 2020 alone, nearly 10 million children were displaced in the aftermath of weather-related shocks. With around one billion children – nearly half of the world’s 2.2 billion children – living in 33 countries at high risk of the impacts of climate change, millions more children could be on the move in the coming years.
Developed in collaboration with young climate and migration activists, academics, experts, policymakers, practitioners, and UN agencies, the guiding principles are based on the globally ratified Convention on the Rights of the Child and are further informed by existing operational guidelines and frameworks.
Recommendations for safeguarding the rights and well-being of children regardless of their location or migration status.
The guiding principles provide national and local governments, international organizations and civil society groups with a foundation to build policies that protect children’s rights. The organizations and institutions are calling on governments, local and regional actors, international organizations, and civil society groups to embrace the guiding principles to help protect, include, and empower children on the move in the context of climate change.

Leishmaniasis is a vector-borne disease with a wide variety of parasite species, reservoirs, and vectors involved in transmission. It is caused by different species of the protozoa Leishmania and is transmitted to animals and humans through a bite of insects in the Psychodidae family. Its presence i...s directly linked to poverty, but social, environmental, and climatalogic factors directly influence the disease's epidemiology.

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

The control and elimination of schistosomiasis have over the last two decades involved several strategies, with the current strategy by the World Health Organization (WHO) focusing mainly on treatment with praziquantel during mass drug administration (MDA). However, the disease context is complex wi...th an interplay of social, economic, political, and cultural factors that may affect achieving the goals of the Neglected Tropical Disease (NTD) 2021-2030 Roadmap. There is a need to revisit the current top-down and reactive approach to schistosomiasis control among sub-Saharan African countries and advocate for a dynamic and diversified approach.

Diabetes mellitus (DM) is a global epidemic with significant morbidity. Diabetic
retinopathy (DR) is the specific microvascular complication of DM and affects 1 in 3 persons with DM. DR remains a leading cause of vision loss in working adult populations. Patients with severe levels of DR are report...ed to have poorer quality of life and reduced levels of physical, emotional, and social well-being, and they utilize more health care resources.
Epidemiological studies and clinical trials have shown that optimal control of blood glucose, blood pressure, and blood lipids can reduce the risk of developing retinopathy and slow its progression. Timely treatment with laser photocoagulation, and increasingly, the appropriate use of intraocular administration of vascular endothelial growth factor (VEGF) inhibitors can prevent visual loss in vision- threatening retinopathy, particularly diabetic macular edema (DME). Since visual loss may not be present in the earlier stages of retinopathy, regular screening of persons with diabetes is essential to enable early intervention.

We combine data on Chinese development projects with data from Demographic and Health Surveys to study the impact of Chinese aid on household welfare in sub-Saharan Africa. We use a novel methodology to test the effect of Chinese aid on three important development outcomes: education, health, and nu...trition. For each outcome, we use difference-in-difference estimations to compare household areas near Chinese project sites to control areas located farther away, before and after receiving Chinese aid. This empirical strategy rules out many confounding factors that can bias measuring the impact of Chinese aid on our outcome variables. First, we find that Chinese projects significantly improve education and child mortality in treatment areas, but do not significantly affect nutrition. Second, social sector projects have a larger effect on outcomes than economic projects. Third, we do not find significant effects for projects that ended more than five years before the post-treatment survey wave. Our results are robust to a host of robustness checks.

Cardiovascular diseases, principally ischemic heart disease (IHD), are the most important cause of death and disability in the majority of low- and lower-middle-income countries (LLMICs). In these countries, IHD mortality rates are significantly greater in individuals of a low socioeconomic status (...SES).
Three important focus areas for decreasing IHD mortality among those of low SES in LLMICs are (1) acute coronary care; (2) cardiac rehabilitation and secondary prevention; and (3) primary prevention. Greater mortality in low SES patients with acute coronary syndrome is due to lack of awareness of symptoms in patients and primary care physicians, delay in reaching healthcare facilities, non-availability of thrombolysis and coronary revascularization, and the non-affordability of expensive medicines (statins, dual anti-platelets, renin-angiotensin system blockers). Facilities for rapid diagnosis and accessible and affordable long-term care at secondary and tertiary care hospitals for IHD care are needed. A strong focus on the social determinants of health (low education, poverty, working and living conditions), greater healthcare financing, and efficient primary care is required. The quality of primary prevention needs to be improved with initiatives to eliminate tobacco and trans-fats and to reduce the consumption of alcohol, refined carbohydrates, and salt along with the promotion of healthy foods and physical activity. Efficient primary care with a focus on management of blood pressure, lipids and diabetes is needed. Task sharing with community health workers, electronic decision support systems, and use of fixed-dose combinations of blood pressure-lowering drugs and statins can substantially reduce risk factors and potentially lead to large reductions in IHD. Finally, training of physicians, nurses, and health workers in IHD prevention should be strengthened.

Cardiovascular disease is a major cause of disability and premature death throughout the world, and contributes substantially to the escalating costs of health care. The underlying pathology is atherosclerosis, which develops over many years and is usually advanced by the time symptoms occur, genera...lly in middle age. Acute coronary and cerebrovascular events frequently occur suddenly, and are often fatal before medical care can be given. Modification of risk factors has been shown to reduce mortality and morbidity in people with diagnosed or undiagnosed cardiovascular disease.
This publication provides guidance on reducing disability and premature deaths from coronary heart disease, cerebrovascular disease and peripheral vascular disease in people at high risk, who have not yet experienced a cardiovascular event. People with established cardiovascular disease are at very high risk of recurrent events and are not the subject of these guidelines. They have been addressed in previous WHO guidelines.
Several forms of therapy can prevent coronary, cerebral and peripheral vascular events. Decisions about whether to initiate specific preventive action, and with what degree of intensity, should be guided by estimation of the risk of any such vascular event. The risk prediction charts that accompany these guidelinesb allow treatment to be targeted accord-
ing to simple predictions of absolute cardiovascular risk.
Recommendations are made for management of major cardiovascular risk factors through changes in lifestyle and prophylactic drug therapies. The guidelines provide a framework for the development of national guidance on prevention of cardiovascular disease that takes into account the particular political, economic, social and medical circumstances.

Our aim is to review current asthma epidemiology, achievements from the last 10 years, and persistent challenges of asthma man- agement and control in low-middle income countries (LMICs). Despite global efforts, asthma continues to be an important public health problem worldwide, particularly in poo...rly resourced settings. Several epidemiological studies in the last decades have shown significant variability in the prevalence of asthma globally, but generally a marked increase in LMICs resulting in significant mor- bidity and mortality. Poverty, air pollution, climate change, exposure to indoor allergens, urbanization and diet are some of the factors that contribute to inadequate control and poor outcomes in developing countries. Although asthma guidelines have been developed to raise awareness and improve asthma diagnosis and treatment, problems with underdiagnosis and undertreatment are still common. In addition, important social, financial, cultural and healthcare barriers are common obstacles in LMICs in achieving control. Given the high burden of asthma in these countries, adaptation and implementation of national asthma guidelines tailored to local needs should be a public health priority. Governmental commitment, education, better health system infrastructure, access to care and effective asthma medications are the cornerstone of achieving success.

In Latin America and the Caribbean (LAC), one maternal death was registered every hour in 2020. That same year, the trend in the maternal mortality ratio (MMR) for the Region of the Americas regressed alarmingly and unprecedentedly to the levels seen two decades ago. In addition to indicating a wors...ening of health outcomes, these figures also signal a deepening of inequalities, representing thousands of individual, unacceptable tragedies that in most cases could have been preventable. Maternal death is the result of a multifactorial process in which structural elements such as the economic system, environmental conditions, and culture interact. Other factors related to social inequality are also present, such as racism, poverty, gender inequality, and lack of access to the education system. The current situation calls for urgent mobilization of the health systems of LAC countries in order to strengthen efforts to combat maternal mortality, especially in countries that are still far from achieving the SHAA2030 regional target. For this reason, a preventive, health-promoting, life-course-based approach is needed, with models of care centered on women, families, and the community Scientific evidence shows that health systems with a solid foundation in primary health care (PHC) achieve better outcomes, greater equity, and reduced health expenditures. To address this, PAHO proposes a strategy, aimed primarily at women who are in the most vulnerable situation, who are the ones who represent the greatest burden of maternal mortality, to accelerate the reduction of maternal mortality in the Region of the Americas, based on the expansion and strengthening of PHC.
