The aim of this report was to identify the basic sanitary situation and that of a series of health markers, in the area of influence of our health centre. The population studied have all come from places under the census and the measuring system used was a prepared survey and also, direct observation. The information collected was verified by revising all the clinical notes of the affected people. The results found are presented, referring to the characteristics of the houses and the stables, the sanitary situation of the livestock, water supply and excrement removal, rubbish removal methods and health markers. The high number of houses without adequate installation maintenance (water, excrement...) and the high incidence of infectious diseases should be highlighted.
