Alterações climáticas e saúde. O vídeo da Direcção Geral da Saúde (I)

Por sugestão da Sílvia, fui visionar o filme da Direcção Geral da Saúde alusivo ao Dia Mundial da Saúde.
Porque o achei muito interessante (talvez do mais interessante que tenho vista a DGS fazer nos últimos tempos) deixo-o aqui.
Apreciem!

Environmental Health in Emergencies and Disasters

Hoje sugiro-vos a leitura do livro “Environmental Health in Emergencies and Disasters: A Pratical Guide” (Saúde Ambiental em Emergências e Catástrofes: Um Guia Prático) de Ben Wisner e John Adams.
As emergências e catástrofes podem ocorrer em qualquer lugar do mundo, afectando a saúde humana, a vida das pessoas e as infra-estruturas construídas para apoiá-los. Os problemas de saúde ambiental decorrentes de emergências e catástrofes estão ligados aos seus efeitos sobre o desenvolvimento físico, biológico e ambiente social, constituindo uma ameaça para a saúde humana, bem-estar e sobrevivência: abrigo, água, saneamento, vectores de doença, poluição, etc.
Este livro aborda a gestão deste tipo de problemas, particularmente sob o ponto de vista do indivíduo/profissional com responsabilidades na área da saúde ambiental, antes, durante e depois de emergências e catástrofes.
Um livro que interessará a Técnicos de Saúde Ambiental, Médicos de Saúde Pública, Engenheiros Sanitaristas e muitos outros profissionais com responsabilidades nesta área.

Protecting health from climate change

Ainda a propósito do Dia Mundial da Saúde e dos efeitos que as alterações climáticas têm na saúde, deixo-vos o artigo de Riffat Hossain Lucy publicado, no dia 4 de Abril de 2008, no The Daily Star.

«World Health Day — 7 April, marks the founding of the World Health Organisation (WHO). It draws attention to a subject of major importance of global health every year.

In 2008, World Health Day focuses on the need to protect health from the adverse effects of climate change. The theme of this year, Protecting health from climate change” puts health at the centre of the global dialogue about climate change.

WHO selected this theme in recognition that climate change is posing ever growing threats to global public health security. Health is one of the areas most affected by the climate change.

The Earth’s atmosphere is very thin, half lies within three miles of its surface and the concentration of CO2 in the atmosphere is rising fast. There is now no serious dispute that this is causing a rapid rise in the Earth’s temperature and that this brings with it imminent dangers.

The threat to human health is of a more fundamental kind than is the threat to the world’s economic system, says Prof McMichael, a Professor of Public Health from the
Australian National University. “Climate change is beginning to damage our natural life-support system, he added.

The World Health Organisation estimates that a quarter of the world’s disease burden is due to the contamination of air, water, soil and food — particularly from respiratory infections and diarrhoeal disease.

Climate change will make these and other diseases worse. While it is unlikely to cause entirely new diseases, but it will alter the incidence, range and seasonality of many existing health disorders.

By 2080, between 20 and 70 million more people could be living in malarial regions due to climate change. Health hazards from climate change are diverse and global in nature. The hazards range from higher risks of extreme weather events to changes in the dynamics of infectious diseases. Many of the leading killer diseases are sensitive to climatic conditions; their incidence and spread are likely to be affected by changing weather patterns. The health impacts of climate change are already evident in different ways: more people are dying from excessive heat than before, changes are occurring in the incidence of vector-borne diseases and the pattern of natural disasters is altering.

These health hazards and impacts will be disproportionately greater among the vulnerable populations, which include the very young, elderly, medically infirm, poor and isolated populations. Vulnerability is also observed to be high in areas with a high endemicity of climate-sensitive diseases, severe water scarcity, and low food production. Spotlight should also focus the small-island developing states and mountainous regions; and mega-cities and coastal areas in developing countries.

Evidence and research have supported that if current warming trends remain uncontrolled, humanity will face more injury, disease and death related to natural disasters and heatwaves; higher rates of foodborne, waterborne, and vector-borne illness; and more premature deaths and disease related to air pollution.

Moreover, in many parts of the world, large populations will be displaced by rising sea level and affected by drought and famine. As glaciers melt, the hydrological cycle shifts and the productivity of arable land changes.

In fact, Poverty cannot be eliminated overnight while environmental degradation exacerbates malnutrition, disease and injury. Food supplies need continuing soil fertility, climatic stability, freshwater supplies and ecological support (such as pollination). Infectious diseases cannot be stabilised in circumstances of climatic instability, refugee flows and impoverishment.

Goals for World Health Day 2008
1. Raise awareness and public understanding of the global and locally relevant health consequences of climate change.

2. Advocate for interdisciplinary and intersectoral partnerships from the local to international level that seek to improve health through rapid deployment of mitigation strategies to stabilise climate change and development of proactive adaptation programmes to minimise health impacts.

3. Generate effective actions by local communities, organisations, health systems and governments to reduce the impact of climate change on health through urgent application of mitigation and adaptation techniques.

4. Demonstrate the health community’s role in facing the challenges globally and in regions, countries and communities.

5. Spark commitment and action among governments, international organisations, donors, civil society, businesses and communities (especially among young people) to anchor health at the heart of the climate change agenda. The health impacts of climate change will be difficult to reverse in near coming years or even decades. But some of potential impacts can be avoided or prevented. Controlling disease vectors (fly, mosquito, flea), reducing pollution from transport, and efficient land use and water management can be measures given emphasis. Clean water and sanitation; safe and adequate food; immunisation; disease surveillance and response; safe and effective disease vector control; and disaster preparedness are all critical components of public health practices that are also adaptations to climate change. These programmes need to be strengthened globally with special concentration of effort in high-risk locations and populations in order to prevent climate-related injury, disease and death.

Some steps needed to prevent climate change have positive health benefits. For example, increased use of bicycles and public transport instead of personal cars in industrialised countries will reduce greenhouse gas emissions. It will also improve air quality and lead to better respiratory health and fewer premature deaths. The increase in physical activity from cycling and walking may lead to less obesity and fewer obesity-related illness. The sooner these steps are taken, the greater their impact will be on public health.»

Dia Mundial da Saúde 2008: a protecção da saúde dos efeitos das alterações climáticas

Comemora-se no próximo dia 7 de Abril o Dia Mundial da Saúde cujo tema será “a protecção da Saúde dos efeitos das alterações climáticas“, pretendendo-se “alertar a opinião pública para a tomada de consciência dos efeitos que as alterações climáticas produzem na Saúde e promover a colaboração e intervenção por parte do cidadão em geral.”

Em Portugal, o evento comemorativo terá lugar, nesse mesmo dia (segunda-feira), às 10h30, no Auditório do INFARMED – Parque da Saúde (informação recolhida no sítio do Alto Comissariado da Saúde e na Direcção Geral da Saúde). Mais informações aqui.

Alusivo a este dia, sugiro-vos a leitura da mensagem da Directora-Geral da Organização Mundial da Saúde (OMS).

«World Health Day, on 7 April, marks the founding of the World Health Organization and is an opportunity to draw worldwide attention to a subject of major importance to global health each year.

The theme “protecting health from climate change” puts health at the centre of the global dialogue about climate change. WHO selected this theme in recognition that climate change is posing ever growing threats to global public health security.

Through increased collaboration, the global community will be better prepared to cope with climate-related health challenges worldwide. Examples of such collaborative actions are: strengthening surveillance and control of infectious diseases, ensuring safer use of diminishing water supplies, and coordinating health action in emergencies.»

Água imprópria para consumo nas nascentes do concelho de Sintra

De acordo com a Agência Lusa, em notícia publicada no Sol, “todas as 42 nascentes do concelho de Sintra analisadas por um grupo de peritos contêm água imprópria para consumo, tendo sido recomendada à Autoridade de Saúde a afixação de avisos à população e o encerramento de algumas bicas e fontanários.”

Em 2006 chegámos a acompanhar alguns colegas na colheita de amostras de água para o estudo efectuado por investigadores do Instituto Nacional de Saúde Dr. Ricardo Jorge (INSA), que hoje divulgaram no 9º Congresso da Água, organizado pela Associação Portuguesa dos Recursos Hídricos (APRH), que 38 das 42 nascentes estudadas contêm água classificada de “alto risco” para a saúde pública devido a contaminação fecal.

Segundo uma das autoras do estudo, “a origem dessa contaminação pode estar relacionada com fossas sépticas, rupturas na rede de esgotos ou até, no que respeita às nascentes em meios rurais, por causa dos dejectos de galinhas ou ovelhas”

A água de nascentes naturais, de muito dos fontenanáros e bicas, objecto do estudo, continua a ser cobiçada pela população local, que parte em romaria para poder encher os seus garrafões.

Contrariando a ideia de que as águas naturais têm melhor qualidade do que as da rede pública de abastecimento público, nomeadamente no concelho de Sintra, as conclusões do estudo basearam-se em análises a várias nascentes da vila de Pero Pinheiro, Sintra, Queluz e Algueirão-Mem Martins.
