[Evaluation of practice and costs of vector control on a family level in Central Africa. II. Douala City (Cameroon), July 1988]. / Evaluation des pratiques et des coûts de lutte antivectorielle à l'échelon familial en Afrique centrale. II. Ville de Douala (Cameroun), juillet 1988.

A Knowledge, Attitude, Practice survey was carried out in July 1988 in Douala city, by cluster sampling and household visits. 98% of these households declared being disturbed by mosquitoes (bites, diseases, noise); 91% of families are using a vector control method; the main methods are: bed-nets (48%), insecticide sprays (39.5%) and mosquito coils (36.7%). The average cumulated expense by households for vector control (116.6 ECU/year) and care for diseases attributed to mosquitoes (147.4 ECU/year) was evaluated at the equivalent of about 3 months of "minimum monthly wages". More than 90% of people interviewed would accept buying and using an insecticide impregnated bed-net provided that the price of such a product be lower than the current habitual price for ordinary bed-nets. The distribution of the impregnation technique must be made at the level of impregnation centres, which should start impregnating the existing bed-nets and take care of informing the public.
