[Population contacts in the Republic of Guinea with ectoparasites and rodents based on questionnaire data. 1. The tasks and the scope of the questionnaire].

Questionnaire is presented which was used in 1987 in 15 regions (28,400 inhabitants) of 3 landscape climatic areas in Guinea: savanna-forest, light and damp tropical forests. The questionnaire was aimed at obtaining quantitative characteristics on important items of population economic activity and number of potential hosts and carriers of natural focus infections in the buildings. Types of the population occupation were differentiated in conformity with various biotopes the people belong to, and according to their direct contacts with domestic, synanthropic and wild animals. The quantity of little mammals (multi-nipple, gray, black and hamster--like rats, mice, shrews, and bats) and ectoparasites (bloodsucking Ixodes, fleas and lice) and intensity of control thereof were estimated according to 4 grades in 6 types of residential and uninhabited constructions.
