RESUMEN
We have studied asthma mortality in Spain from 1951 to 1985, applying epidemiological descriptive methodology. A global decrease in the tendency is observed when comparing it to other countries. We have observed, however, an increased mortality in the four age groups proposed (5-19, 5-39, 40-64 and 5-64), based on previous international publications which avoid interferences with other causes of death. We have also observed that when applying the method of mortality related to natality rate, there was a decrease in mortality, specially in older generations. Finally, several hypothesis related to risk factors which would explain this tendency are presented.

We have carried out an epidemiological study of Brucellosis in Valencia, studying the evolution of morbidity through this disease from 1943 to 1989. On the other hand, and for the period 1985-1988 we have carried out a study researching the distribution of the illness by sex, age-groups, professions, etc., basing ourselves on the epidemiological surveys corresponding to the 516 cases of Brucellosis declared in this period. We highlight the fact that the dominant mechanism of indirect contagion (mainly through consumption of fresh cheese and untreated milk) constrains the epidemiological pattern of this illness in our area. Thus we believe it is important to maintain and increase the sanitary and hygienic controls of the foods involved in the transmission, mainly the production and distribution of unfermented fresh milk and cheese.
