With technical and financial support from the WHO, the French Ministry of Health has launched a study into household air pollution (HAP). A little-known and little-studied area, PAH may account for more than half of pollution-related health problems, and represents the 3rd risk factor (health determinant) in DALYS in Burkina Faso, as in most West African countries. In Burkina Faso, GBD attributes 35 deaths a day to it. The study will use the HEART (Household Energy Assessment Rapid Tool) as part of the WHO’s CHEST (Clean Household Energy Solutions Toolkit) methodology. The Burkina study will be the first in a French-speaking country. This will be followed by the development of a national intersectoral strategy (health, environment, energy) to combat household pollution.
