    Sammanfattning : This thesis analyses the relationship between risk of exposure to infective Anophelesmosquitoes and different environmental factors, in particular house construction, presence ofdomestic animals and house location, in coastal Guinea Bissau, West Africa. The potentialeffect of permethrin-impregnated bed nets on mosquito abundance in bed rooms, and on thePlasmodium parasite prevalence in children was also analysed. LÄS MER
