Mosquito-borne diseases are expanding their range, and re-emerging in areas where they had subsided for decades. The extent to which climate change influences the transmission suitability and population at risk of mosquito-borne diseases across different altitudes and population densities has not be...en investigated. The aim of this study was to quantify the extent to which climate change will influence the length of the transmission season and estimate the population at risk of mosquito-borne diseases in the future, given different population densities across an altitudinal gradient.

Infectious diseases cause over one billion human infections per year, with millions of deaths each year globally. Extensive health and financial burden is seen from both established and emerging infectious diseases. Infectious diseases also affect plants and animals, which may pose threats to agricu...lture and water supplies with additional impacts on human health. This Question and Answers, prepared by the World Health Organization (WHO) and Convention on Biological Diversity (CBD) Secretariat under their joint work programme on biodiversity and health, and launched of the occasion of the International Day for Biodiversity 2020, summarizes some of the interlinkages between biodiversity and infectious diseases.
WHO is continuously monitoring and responding to the COVID 19 outbreak. This Q&A will be updated as more is known about COVID-19, how it is affecting people worldwide, and the effectiveness of interventions against the disease.

Extreme heat events (EHEs) are a leading cause of weather-related injury and death in the United States, and under a changing climate, these meteorological episodes are predicted to increase in both frequency and intensity. Prolonged heat exposure from EHEs places an increased strain on the heart an...d may lead to heat-related illness if the cardiovascular system fails to properly thermoregulate internal body temperature. Every individual is susceptible to heat-related illness, however, those with reduced cardiovascular function and pre-existing cardiovascular diseases are at a greater risk for morbidity and mortality during EHEs. This document gives an overview of our current understanding of heat exposure and its impact on cardiovascular health outcomes, an overview of the medications that may exacerbate heat-related cardiovascular illness, and asummary of the interaction between extreme heat and air pollutants, and their collective impact on cardiovascular health. Additionally, this document summarizes epidemiologic evidence and identifies gaps in the extant peer-reviewed literature on the effectiveness of strategies and interventions to protect against heat-related cardiovascular disease and death. This information is intended to aid health departments and other health professionals in understanding and responding to the impacts of heat exposure on cardiovascular health.

Climate change is expected to have complex effects on infectious diseases, causing some to increase, others to decrease, and many to shift their distributions. There have been several important advances in understanding the ...role of climate and climate change on wildlife and human infectious disease dynamics over the past several years. This essay examines 3 major areas of advancement, which include improvements to mechanistic disease models, investigations into the importance of climate variability to disease dynamics, and understanding the consequences of thermal mismatches between host and parasites. Applying the new information derived from these advances to climate–disease models and addressing the pressing knowledge gaps that we identify should improve the capacity to predict how climate change will affect disease risk for both wildlife and humans.

The report is geared towards mayors, local government officials and city policy planners.It highlights key areas where city leaders can tackle the drivers of NCDs, including tobacco use, air pollution, poor diets and lack of exercise, and improve road safety.
From anti-tobacco actions in Beijing a...nd Bogor, to road safety initiatives in Accra and Bangkok, a bike sharing scheme in Fortaleza, and actions to create walkable streets for seniors that have reduced elderly pedestrian deaths by 16% in New York City, the report aims to share knowledge between urban policy planners.
Of the 19 case studies cited, 15 are from developing countries, where 85% of premature adult deaths through NCDs take place, and over 90% of road traffic fatalities are recorded. You can download the case studieson the website https://www.who.int/ncds/publications/tackling-ncds-in-cities/en/.
Over 90% of future urban population growth will be in low or middle-income countries, and seven of the world’s 10 largest cities are in developing countries.

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.

Nations will more quickly transition to clean energy if they redirect government funds away from subsidising unhealthy commodities– in particular fossil fuels. Such action would reduce air pollution and greenhouse gas emissions, thereby mitigating climate change and saving lives. Countries must re...examine current economic incentives to industries that harm health as an essential step towards creating coherent policies that sustain growth, support clean energy expansion and prevent noncommunicable diseases (NCDs).

Climate change presents significant challenges to human health and biodiversity. Increased numbers of extreme climate events, such as heat waves, droughts or flooding, threaten human health and well-being, both directly and indirectly, through impaired ecosystem functioning and reduced ecosystem ser...vices. In addition, the prevalence of non-communicable diseases is rising, causing ill health and accelerating costs to the health sector. Nature-based solutions, such as the provision and management of biodiversity, can facilitate human health and well-being, and mitigate the negative effects of climate change.

In 2007, WHO warned that infectious diseases are emerging and re-emerging at a rate that has not been seen before. The potential for infectious diseases to spread rapidly results in high morbidity and mortality, causing a potential global public health treat of major concern.
Several factors are ...contributing to the (re)emergence of infectious diseases such as population growth, living in close contact with animals, frequent travelling, poverty, destructive ecological changes due to economic development and land use and climate change result in global warming.
Especially Africa is at a threat for (re)emerging infectious diseases due to the huge population growth (expected to reach 2.5 billion by 2050) with rapid urbanisation. Additionally, people across and beyond the continent are excessively mobile which is combined with a weak health system. Moreover, the risk of (re)emerging infectious disease is further heightened by three newly adopted continental initiatives: African Continental Free Trade Area, Free Movement of Persons and African Passport and Single African Air Transport Market.

Cardiovascular disease, diabetes, chronic obstructive pulmonary disease, cancers, and other non-communicable diseases are among the leading causes of morbidity and mortality in low-income, middle-income, and high-income countries, and The Lancet Taskforce recently made the case for investing in non-...communicable disease prevention. Now, in The Lancet Planetary Health, Benjamin Bowe and colleagues report that exposure to PM2·5 air pollution is indeed a risk factor for diabetes.

Exposure to air pollution causes 7 million deaths worldwide every year and costs an estimated US$ 5.11 trillion in welfare losses globally. In the 15 countries that emit the most greenhouse gas emissions, the health impacts of air pollution are estimated to cost more than 4% of their GDP. Actions to... meet the Paris goals would cost around 1% of global GDP. The report provides recommendations for governments on how to maximize the health benefits of tackling climate change and avoid the worst health impacts of this global challenge.
It describes how countries around the world are now taking action to protect lives from the impacts of climate change – but that the scale of support remains woefully inadequate, particularly for the small island developing states, and least developed countries. Only approximately 0.5% of multilateral climate funds dispersed for climate change adaptation have been allocated to health projects
