DHS Working Papers No. 85
This report presents a framework to link science, policy and practice for a comprehensive assessment of climate mitigation and adaptation investments and their impact on human health.The framework proposes to use weather and climate data to forecast health impacts over time, as well as biophysical a...nd economic models to quantify the outcomes of investments in climate change adaptation and mitigation for relevant sectoral indicators and health co-benefits. It provides guidance on the economic valuation of health co-benefits of climate action, for inclusion in sector-specific cost–benefit analysis (CBA), including the spatial allocation of such costs and benefits.
The framework developed and presented in this study is comprehensive, and provides various entry points for different audiences, including decision-makers in the public and private sectors, researchers and scientists, working in the health sector as well as in other thematic areas and related sectors affected by climate action.

This chapter reviews the emerging importance of pollen allergies in relation to ongoing climate change. Allergic diseases have been increasing in prevalence over the last decades, partly as the result of the impact of climate change. ...Increased sensitisation rates and more severe symptoms have been the partial outcome of: increased pollen production of wind-pollinated plants resulting in long-term increased abundance of pollen in the air we breathe; earlier shifts of airborne pollen seasons making occurrence of allergic symptoms harder to predict and deal with efficiently; increased allergenicity of pollen causing more severe health effects in allergic individuals; introduction of new, invasive allergenic plant species causing new sensitisations; environment-environment interactions, such as plants and hosted microorganisms, i.e. fungi and bacteria, which comprise a complex and dynamic system, with additive, presently unforeseeable influences on human health; environment-human interactions, as the consequence of a combination of environmental factors, like air pollution, global warming, urbanisation and microclimatic variability, which create a multi-resolution spatiotemporal system that requires new processing technologies and huge data inflow in order to be thoroughly investigated. We suggest that novel, real-time, personalised pollen information services, like mobile-app risk alerts, must be developed to provide the optimum first line of allergy management.

The policy brief focuses on four key areas for intervention - air pollution, energy, transport and food systems. Air pollution causes 7 million deaths annually, and is a leading cause of both NCDs and climate change, thus all interventions to reduce air pollution have a positive impact on both human... and planetary health. In the energy sector, transition from fossil fuels to renewable energy is if vital importance to improving health, with mortality rates due to coal-generated electricity 1,000 times higher than for wind-generated electricity.
Promoting active transport such as walking and cycling in place of motorised transport has the dual benefit of reducing both air pollution and physical activity. Livestock production alone accounts for 18% of greenhouse gas emissions, with added emissions from food which are highly process and transported over long distances, and thus locally sourced plant based diets both prevent NCDs and promote human and planetary health.

Malaria is an important disease that has a global distribution and significant health burden. The spatial limits of its distribution and seasonal activity are sensitive to climate factors, as well as the local capacity to control the disease. Malaria is also ...one of the few health outcomes that has been modeled by more than one research group and can therefore facilitate the first model intercomparison for health impacts under a future with climate change. We used bias-corrected temperature and rainfall simulations from the Coupled Model Intercomparison Project Phase 5 climate models to compare the metrics of five statistical and dynamical malaria impact models for three future time periods (2030s, 2050s, and 2080s). We evaluated three malaria outcome metrics at global and regional levels: climate suitability, additional population at risk and additional person-months at risk across the model outputs. The malaria projections were based on five different global climate models, each run under four emission scenarios (Representative Concentration Pathways, RCPs) and a single population projection. We also investigated the modeling uncertainty associated with future projections of populations at risk for malaria owing to climate change. Our findings show an overall global net increase in climate suitability and a net increase in the population at risk, but with large uncertainties. The model outputs indicate a net increase in the annual person-months at risk when comparing from RCP2.6 to RCP8.5 from the 2050s to the 2080s. The malaria outcome metrics were highly sensitive to the choice of malaria impact model, especially over the epidemic fringes of the malaria distribution.

INTRODUCTION: The COVID-19 pandemic has disrupted health systems around the world. The objectives of this study are to estimate the overall effect of the pandemic on essential health service use and outcomes in Mexico, describe observed and predicted trends in services over 24 months, and to estimat...e the number of visits lost through December 2020.
METHODS: We used health information system data for January 2019 to December 2020 from the Mexican Institute of Social Security (IMSS), which provides health services for more than half of Mexico's population-65 million people. Our analysis includes nine indicators of service use and three outcome indicators for reproductive, maternal and child health and non-communicable disease services. We used an interrupted time series design and linear generalised estimating equation models to estimate the change in service use and outcomes from April to December 2020. Estimates were expressed using average marginal effects on the risk ratio scale.
RESULTS: The study found that across nine health services, an estimated 8.74 million patient visits were lost in Mexico. This included a decline of over two thirds for breast and cervical cancer screenings (79% and 68%, respectively), over half for sick child visits and female contraceptive services, approximately one-third for childhood vaccinations, diabetes, hypertension and antenatal care consultations, and a decline of 10% for deliveries performed at IMSS. In terms of patient outcomes, the proportion of patients with diabetes and hypertension with controlled conditions declined by 22% and 17%, respectively. Caesarean section rate did not change.
CONCLUSION: Significant disruptions in health services show that the pandemic has strained the resilience of the Mexican health system and calls for urgent efforts to resume essential services and plan for catching up on missed preventive care even as the COVID-19 crisis continues in Mexico.

Over long periods of time, individuals and communities can adapt to their local climates. When both warmer and colder temperatures go above or below those norms rapidly, scientific evidence shows that people become vulnerable to associated health effects related to those extremes. Studies suggest th...at climate change will greatly increase the severity and frequency of extreme temperature conditions, leading to increases in temperature-related illness and death

Over 18 months into the pandemic, WHO continues to conductglobal surveillance of COVID-19as part of activities on preparedness, readiness and response activities. The need for global surveillance of COVID-19 is greater than ever, asthe implementation of vaccination campaigns and the appearance of va...riants are prone to impact the course of the epidemic, as transmission patterns evolve. Timely and complete surveillance data are key to monitoring these changes.
Features include stratification by age and sex, trends over time, case fatality ratios by age, testing, hospitalization, and data on health workers –all visible at country and regional levels. The dashboard provides the ability for users to conduct further analyses by country and selected time period.

The health sector In Ukraine is beginning to change in recent years. The sector, based on a system of health care (Semashko) originating from the Soviet Union, had been stagnant for many years. Remarkably little had changed since Independence and the health care system is as of today still character...ized by a very hierarchical and territorial system with large numbers of beds in institutional care settings. At the same time the Government of Ukraine has only limited resources available that are spread thin over the existing infrastructure

Antimicrobial resistance (AMR) is described as a situation when bacteria, viruses, fungi and parasites
change over time and no longer respond to medicines, making infections harder or impossible to treat,
and increasing the risk of disease spread, severe illness and death.1 AMR in recent years has... become
a global priority in public health due to its widespread consequences and increasing occurrence from
time to time. AMR has a formidable impact where the existing antibiotics and other antimicrobial
medicines become ineffective, and infections become increasingly difficult or impossible to treat.

Pakistan, one of the countries that is most vulnerable to climate change, received more than three times its usual rainfall in August 2022. Torrential rains and flash-flooding began in early July 2022, severely damaging living areas, schools and other communal buildings in refugee villages and host ...communities. Unprecedented and unrelenting rainfall and flooding in late August 2022 worsened the already fragile humanitarian situation. Nearly 1,700 people are reported to have died, and over 12,800 were injured, including at least 4,000 children

Issue Brief 31: Antimicrobial resistance (AMR) can occur when viruses, bacteria, parasites and fungi change over time. There is no longer a response to medicines, and the infection treatment gets really difficult which increases the risk of a disesase spread, which can lead to severe health problems.... AMR is an increasing threat to global public health worldwide that requires cross-sectional and cross-disciplinary action. It is present in every country and is spurred by several human-made factors, including over- and/or inadequate use of antibiotics, poor hygiene and infection prevention control, and excessive usage of antibiotics outside the health care sector e.g. in life stock production.

This paper uses data from the three Indian National Family Health Surveys (1992-93, 1998-99, 2005-06) to examine how the relationship between household wealth and child mortality evolved during a time of significant economic change in India. The main predictor is a new... measure of household wealth that captures changes in wealth over time. Outcomes include neonatal mortality, postneonatal mortality, child mortality, and under-five mortality. Multivariate analysis is conducted at the national, urban, rural, and regional levels.
Results indicate that the overall relationship between household wealth and mortality weakened over time, as evidenced by the coefficients for under-five mortality at the national level.

Over the span of a few weeks during July and August 2014, events in West Africa changed perceptions of Ebola virus disease (EVD) from an exotic tropical disease to a priority for global health securi...ty. We describe observations during that time of a field team from the Centers for Disease Control and Prevention and personnel of the Liberian Ministry of Health and Social Welfare. The authors outline the early epidemiology of EVD within Liberia, including the practical limitations on surveillance and the effect on the country’s health care system, such as infections among health care workers

The way we talk about global issues affects how people think, feel and react to them. Recognising that language has the power to create social change, we have produced this guide with the inten-tion of setting out a different approach to communicating global issues—one that replaces the nar-rative... of development, aid and charity, with one of global justice and solidarity. The work presented here will continue to be developed over time as we continue to research and test these messages.
