Oxfam Water Supply Scheme for Emergencies. This manual is part of a series of guides devised by the Oxfam Public Health Engineering Team to help provide a reliable water supply for populations affected by conflict or natural disaster. Wherever possible, water supplies in emergency conditions should ...be obtained from underground sources by exploitation of springs, tubewells, or dug wells. No filtration will then be needed. However, if sources are not available or cannot be developed, the use of surface water from streams, rivers, lakes or ponds becomes necessary. Usually these surface sources are polluted. The level of faecal contamination can be measured by use of the Oxfam/Delagua Water Test Kit (see Section C). Where a serious level of faecal pollution exists, it is essential firstly to try to reduce the cause of contamination, and secondly to treat the water to make it suitable for human consumption. The Filtration equipment provides a simple, long-term physical and biological treatment system that requires no chemicals (except small amounts of chlorine required during filter cleaning) and needs only simple regular maintenance

Environmental Pollution
http://dx.doi.org/10.1016/j.envpol.2013.05.046
Over half a billion children are living in areas with extremely high levels of floods and nearly 160 million children live in areas of high or extremely high droughts. The World Health Organisation (WHO) estimates that 26% of the annual 6.6 million deaths of children under five are linked to environ...ment-related causes and conditions. Children are also disproportionately affected by pollution, not only in terms of death rates, but also in terms of cognitive and physical development. This report illustrates that environmental causes also have an impact on whether children are pushed to work and on the kind of work they engage in, the conditions of work, exposure to dangerous toxicants and the risk of exploitation. However, the report raises more questions than it answers as it is one of the first reports addressing the question, how environmental degradation and climate change affect the vulnerability of children towards exploitation.

El objetivo fue determinar cuáles son las percepciones de distintos actores del sistema de salud
colombiano sobre los problemas del sistema que están detrás de la crisis. Se realizó un estudio
cualitativo a partir de entrevistas semiestructuradas y en profundidad con cuarenta agentes del
sect...or salud, en Bogotá, Cali, Ibagué, Espinal y Calima-Darién. Los resultados mostraron que la
corrupción, el incumplimiento de normas y los conflictos entre los intereses de diversos actores
del sistema debilitan la legitimidad de este último, atomizan la cooperación y cohesión de los
actores y fortalecen el interés particular.

Non-Motorized Transport (NMT) has immense benefits for individual users, as well as society at large, through improvements to physical health, air quality, the environment, climate change, personal finance, accessibility, mobility and the empowerment of vulnerable groups.
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.

We live in a world in which global warming, pollution, social
injustice, inequity and population health fundamentally influence each other. As a result, health and health care can no longer be thought of and practiced in an isolated manner.
The authors conduct an integrated survey of Antimicrobial Resistant Organisms (AMR) in drinking water, wastewater and surface water in three settings in Bangladesh: rural households, rural poultry farms, and urban food markets. Results show that untreated water discharged from rural households, poul...try farms and urban markets are major contributors to surface water pollution and antibiotic resistant bacteria genes, calling for increased surveillance and monitoring.

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.

Globally, environmental pollution and other environmental risks cause 24% of all deaths, and these deaths are largely preventable. A shift towards policies and actions that minimize risks to health and promote health and sustainable personal and societal choices will reduce environmental risks to he...alth. These changes will result in many more people enjoying good health, living in appealing and unspoiled environments and in fewer people requiring health care, which will lower health care
expenditures.

Many features of the environment have been found to exert an important influence on cardiovascular disease (CVD) risk, progression, and severity. Changes in the environment due to migration to different geographic locations, modifications in lifestyle choices, and shifts in social policies and cultu...ral practices alter CVD risk, even in the absence of genetic changes. Nevertheless, the cumulative impact of the environment on CVD risk has been difficult to assess
and the mechanisms by which some environment factors influence CVD remain obscure. Human environments are complex; and their natural, social and personal domains are highly variable due to diversity in human ecosystems, evolutionary histories, social structures, and individual choices. Accumulating evidence supports the notion that ecological features such as the diurnal cycles of
light and day, sunlight exposure, seasons, and geographic characteristics of the natural environment such altitude, latitude and greenspaces are important determinants of cardiovascular health and CVD risk. In highly developed societies, the influence of the natural environment is moderated by the physical characteristics of the social environments such as the built environment
and pollution, as well as by socioeconomic status and social networks. These attributes of the
social environment shape lifestyle choices that significantly modify CVD risk. An understanding
of how different domains of the environment, individually and collectively, affect CVD risk could
lead to a better appraisal of CVD, and aid in the development of new preventive and therapeutic
strategies to limit the increasingly high global burden of heart disease and stroke.

Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ a...nd ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.

Background
Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and ris...k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.
