PREVENTING DISEASE THROUGH HEALTHY ENVIRONMENTS: TOWARDS AN ESTIMATE OF T

HE ENVIRONMENTAL BURDEN OF DISEASE

16 JUNE 2006, GENEVA, NEW DELHI –

As much as 24% of global disease is caused by environmental exposures which can be averted. Well-targeted interventions can prevent much of this environmental risk, the World Health Organization (WHO) demonstrates in a report issued today. The report further estimates that more than 33% of disease in children under the age of 5 is caused by environmental exposures. Preventing environmental risk could save as many as four million lives a year, mostly in developing countries. (I will use this sentence for my slide)

The report, Preventing disease through healthy environments - towards an estimate of the environmental burden of disease, is the most comprehensive and systematic study yet undertaken on how preventable environmental hazards contribute to a wide range of diseases and injuries. By focusing on the environmental causes of disease, and how various diseases are influenced by environmental factors, the analysis breaks new ground in understanding the interactions between environment and health. The estimate reflects how much death, illness and disability could be realistically avoided every year as a result of better environmental management.

"The report issued today is a major contribution to ongoing efforts to better define the links between environment and health," said Dr Anders Nordström, Acting WHO Director-General. "We have always known that the environment influences health very profoundly, but these estimates are the best to date. This will help us to demonstrate that wise investment to create a supportive environment can be a successful strategy in improving health and achieving development that is sustainable."

The report estimates that more than 13 million deaths annually are due to preventable environmental causes. Nearly one third of death and disease in the least developed regions is due to environmental causes. Over 40% of deaths from malaria and an estimated 94% of deaths from diarrhea diseases, two of the world's biggest childhood killers, could be prevented through better environmental management.

The four main diseases influenced by poor environments are diarrhea, lower respiratory infections, various forms of unintentional injuries, and malaria. Measures which could be taken now to reduce this environmental disease burden include the promotion of safe household water storage and better hygienic measures; the use of cleaner and safer fuels; increased safety of the built environment, more judicious use and management of toxic substances in the home and workplace; better water resource management. "For the first time, this new report shows how specific diseases and injuries are influenced by environmental risks and by how much," said Dr Maria Neira, Director of WHO's Department for Public Health and Environment. "It also shows very clearly the gains that would accrue both to public health and to the general environment by a series of straightforward, coordinated investments. We call on ministries of health, environment and other partners to work together to ensure that these environmental and public health gains become a reality."
