Malaria is the first endemic desease in the world. Establishing a map of the prevalence in a small scale for one specific site is a major goal for the next years. Nevertheless, some obstacles remain: Difficulty to organize the numerous decisive factors of the disease into a hierarchy. In urban area: Impact of population, culture diversity and socio-economical status 3
URBANIZATION PROCESS INCREASE IN THE NUMBER HETEROGENOUS AREA INCREASE IN THE NUMBER OF SANITARY (JUXTAPOSITION OF OF CONSTRUCTIONS INFRASTRUCTURES BUILDINGS AND VEGETATION ) INCREASE IN THE BUILDING DENSITY LOWER EXPOSURE RATE BETTER HEALTH CARE INCREASE OF POLLUTION LOW TRANSMISSION DELAY TO GET IMMUNITY AND RESISTANCE PRESUMPTIVE TREATMENT PREVENTIVE CHEMOTHERAPY INCREASE OF SERIOUS CASE OF LOWER MALARIA EXPOSURE MALARIA FOR NON- IMMUNINIZED PEOPLE 4

Aim : To create an index of paludal risk which would tend to include various factors of environmental risk. Nevertheless problems prove to be numerous : Scalar Temporal More technical (balance of factors according to their respective importance) 7
Social economic Infected status mosquitoes rate Mobility Household Demography HUMAN VECTOR BEING Picturing of Location the disease URBAN AREA Urban Soil conditions morphology Weather conditions 8
VULNERABILITY HAZARD Habitat typology (H) Urban typology (T) Prevention (picturing of pathology) (Pr) Flood area (F) Socio-eco-demographic Soil occupation (S) variables (P) UMR Espace, 2008. Variables are selected by stepwise regression 9
« a » and « b » are independant variables and need to be balanced Vulnerability Hazard Comment : Hazard, vulnerability and the risk data are respectively confirmed by entomological and parasitical data. UMR Espace, 2008. 10
This index doesn’t consider: Immunity Mobility Perceptions about the neighbourhood health structures Use of health care services 11
Epidemic spread of malaria in urban setting depends of countless factors. This kind of research shows the interest of and the difficulty to link social aspects and “geographic” ones. Urban environment studies involve a multi-factorial reasoning, close to what the social sciences approach should be. 12
In order to ripen this index, we could insert the healthcare. This index could deal with some following points : City practices: healthcare quality : Perceptions about Meshing of health structures Cost neighbourhood health structures Mobility Quality of treatments Use of health care services during fever crisis 13
