Climate change refers to long-term shifts in weather conditions and patterns of extreme weather events. It may lead to changes in health threat to human beings, multiplying existing health problems. This review examines the scientific e...vidences on the impact of climate change on human infectious diseases. It identifies research progress and gaps on how human society may respond to, adapt to, and prepare for the related changes. Based on a survey of related publications between 1990 and 2015, the terms used for literature selection reflect three aspects — the components of infectious diseases, climate variables, and selected infectious diseases. Humans' vulnerability to the potential health impacts by climate change is evident in literature. As an active agent, human beings may control the related health effects that may be effectively controlled through adopting proactive measures, including better understanding of the climate change patterns and of the compound disease-specific health effects, and effective allocation of technologies and resources to promote healthy lifestyles and public awareness. The following adaptation measures are recommended: 1) to go beyond empirical observations of the association between climate change and infectious diseases and develop more scientific explanations, 2) to improve the prediction of spatial–temporal process of climate change and the associated shifts in infectious diseases at various spatial and temporal scales, and 3) to establish locally effective early warning systems for the health effects of predicated climate change.

Dengue is a mosquito-borne viral disease that occurs mainly in the tropics and subtropics but has a high potential to spread to new areas. Dengue infections are climate sensitive, so it is important to better understand how changing climate factors affect the potential for geographic spread and futu...re dengue epidemics. Vectorial capacity (VC) describes a vector's propensity to transmit dengue taking into account human, virus, and vector interactions. VC is highly temperature dependent, but most dengue models only take mean temperature values into account. Recent evidence shows that diurnal temperature range (DTR) plays an important role in influencing the behavior of the primary dengue vector Aedes aegypti. In this study, we used relative VC to estimate dengue epidemic potential (DEP) based on the temperature and DTR dependence of the parameters of A. aegypti. We found a strong temperature dependence of DEP; it peaked at a mean temperature of 29.3°C when DTR was 0°C and at 20°C when DTR was 20°C. Increasing average temperatures up to 29°C led to an increased DEP, but temperatures above 29°C reduced DEP. In tropical areas where the mean temperatures are close to 29°C, a small DTR increased DEP while a large DTR reduced it. In cold to temperate or extremely hot climates where the mean temperatures are far from 29°C, increasing DTR was associated with increasing DEP. Incorporating these findings using historical and predicted temperature and DTR over a two hundred year period (1901-2099), we found an increasing trend of global DEP in temperate regions. Small increases in DEP were observed over the last 100 years and large increases are expected by the end of this century in temperate Northern Hemisphere regions using climate change projections. These findings illustrate the importance of including DTR when mapping DEP based on VC.

In 2013 the World Health Organization (WHO) published the report Protecting health from climate change:vulnerability and adaptation assessment. The aim was to provide basic and flexible guidance on conducting national or subnational assessments of current and future vulnerability (the susceptibilit...y of a population or region to harm) to the health risks of climate change, and of policies and programmes that could increase resilience, taking into account the multiple determinants of climate-sensitive health outcomes.
That guidance has been a very useful tool, applied to more than 50 countries and settings, and has helped countries to prepare their health contributions to United Nations Framework Convention on Climate Change national adaptation plans.
Since the launch of the guidance, WHO, technical partners such as Health Canada, and countries have learned much in terms of its applicability in different countries, at national and local levels.
At the same time, knowledge on climate change and health has increased.
WHO, the Pan American Health Organization and Health Canada have produced this updated version, which aims to better support countries in their assessments by proposing a simpler tool that incorporates
all lessons learned.

Climate change will increase the frequency and magnitude of extreme weather events and create risks that will impact health care facilities. Health care facilities will need to assess climate chang...e risks and adopt adaptive management strategies to be resilient, but guidance tools are lacking. In this study, a toolkit was developed for health care facility officials to assess the resiliency of their facility to climate change impacts. A mixed methods approach was used to develop climate change resiliency indicators to inform the development of the toolkit. The toolkit consists of a checklist for officials who work in areas of emergency management, facilities management and health care services and supply chain management, a facilitator’s guide for administering the checklist, and a resource guidebook to inform adaptation. Six health care facilities representing three provinces in Canada piloted the checklist. Senior level officials with expertise in the aforementioned areas were invited to review the checklist, provide feedback during qualitative interviews and review the final toolkit at a stakeholder workshop. The toolkit helps health care facility officials identify gaps in climate change preparedness, direct allocation of adaptation resources and inform strategic planning to increase resiliency to climate change.

Transformation and outlook
Cascading risks from rising prices and supply disruptions, April 2022.
Global resource markets are still reeling from the impacts of Russia’s invasion of Ukraine; the two countries are major suppliers of energy, food and fertilizers. Supply disruption and the sudden imposition, in response to the... crisis, of unprecedented economic sanctions, trade restrictions and policy interventions have caused prices of commodities to skyrocket.
Before the conflict, demand for global resources already exceeded supply and drove up prices as economies rebounded after the COVID-19 pandemic. This gave rise to a global cost-of-living crisis, characterized by increasing levels of energy and food poverty. This situation is likely to become much worse as a consequence of the war in Ukraine, and poses a threat to human security, particularly among low-income and vulnerable populations.

The report reveals that good IPC programmes can reduce health care infections by 70 %. oday, out of every 100 patients in acute-care hospitals, seven patients in high-income countries and 15 patients in low- and middle-income countries will acquire at least one health care-associated infection (HAI)... during their hospital stay. On average, 1 in every 10 affected patients will die from their HAI.
People in intensive care and newborns are particularly at risk. And the report reveals that approximately one in four hospital-treated sepsis cases and almost half of all cases of sepsis with organ dysfunction treated in adult intensive-care units are health care-associated.

This report presents the types of cluster munitions being used in the international armed conflict in Ukraine in 2022 and the civilian casualties immediately suffered and civilian objects damaged.
The threat climate change poses to health, equity, and development has been rigorously documented. However, in an era marked by economic crisis, regional conflicts, natural disasters and growing disparities between rich and poor, the joint global actions required to address climate change have been ...vigorously debated – and critical decisions postponed.
This document, part of WHO’s Health in the Green Economy series, describes how many climate change measures can be “win-wins” for people and the planet.
These policies yield large, immediate public health benefits while reducing the upward trajectory of greenhouse gas emissions. Many of these policies can improve the health and equity of people in poor countries and assist developing countries in adapting to climate change that is already occurring, as evidenced by more extreme storms, flooding, drought and heatwaves.
WHO’s Department of Public Health and Environment launched the Health in the Green Economy initiative in 2010 to review potential health and equity “co-benefits” of proposed climate change measures – as well as relevant risks.
This review examines mitigation strategies discussed in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change which constitutes the most broad-based global review of mitigation options by scientific experts.

Child marriage and female genital mutilation (FGM) threaten the well-being of millions of girls around the world. Both have existed for generations, as manifestations of gender inequality, and have been propagated by discriminatory norms that devalue girls. In many countries where both child marriag...e and FGM are common, girls most at risk for each practice tend to share certain characteristics, such as low levels of education, rural residence, and living in poorer households. Yet, there are distinct differences in what drives each practice, and many communities in which one may be common, will not practice the other.
This report seeks to identify the extent to which child marriage and FGM co-exist. The intersection of these two practices – that is, the share of women who underwent FGM and were married in childhood – is reviewed over time, to determine whether girls’ likelihood of experiencing both practices has changed across generations. Lastly, the analysis identifies the characteristics that most commonly distinguish the girls who experience one practice from those who experience both.

Female genital mutilation (FGM), a violation of girls’ and women’s human rights, is becoming less common, and opposition to the practice is growing — in the last two decades, the proportion of girls and women who want the practice to stop has doubled.
However, progress is not universal. In s...ome countries, FGM is as common today as it was three decades ago. Even in places where the practice is on the decline, progress would need to be at least 10 times faster to meet the 2030 target for elimination. Additionally, an alarming trend is emerging: around 1 in 4 girls and women who have undergone FGM, or 52 million worldwide, were cut by health personnel. This proportion is twice as high among adolescents, indicating growth in the medicalization of the practice.
This brochure explores the global FGM trends — progress made in the past three decades, shifts in attitudes, and changes in the circumstances surrounding the practice.

Screening programmes for tuberculosis (TB) among immigrants rarely consider the heterogeneity of
risk related to migrants’ country of origin. We assess the performance of a large screening programme in asylum seekers by analysing (i) the difference in yield and numbers needed to screen (NNS) by c...ountry and WHO-reported TB burden, (ii) the possible impact of screening thresholds on sensitivity, and (iii) the value of WHO-estimated TB burden to improve the prediction accuracy of screening yield.
