National burden of disease due to indoor air pollution
The national burden of disease due to indoor air pollution from solid fuel use was first assessed for the year 2002, then updated for the year 2004. In addition to total deaths and disability-adjusted life years (DALYs) due to indoor air pollution, country-by-country estimates are also available for deaths due to acute lower respiratory infections (ALRI) among children as well as chronic obstructive pulmonary disease (COPD) and lung cancer among adults.
Deaths and DALYs due to indoor air pollution are very unequally distributed:
- Among the 20 worst-affected countries - Afghanistan, Angola, Benin, Burkina Faso, Burundi, Chad, the Democratic Republic of the Congo, Eritrea, Ethiopia, Guinea-Bissau, Liberia, Madagascar, Malawi, Mali, Niger, Rwanda, Sierra Leone, Somalia and Tajikistan - approximately 5% or more of the total burden of disease is caused by indoor air pollution.
- In 10 countries - Afghanistan, Angola, Bangladesh, China, the Democratic Republic of the Congo, Ethiopia, India, Indonesia, Nigeria, and Pakistan - indoor air pollution is responsible for a total of more than 1.5 million deaths a year.
