[Hydatidosis control in the province of Río Negro, Argentina: evaluation of the veterinary health care activities. 1].
BACKGROUND
Hydatidosis constitutes a serious Public Health problem in the Province of Rio Negro, Argentine. This situation has promoted the implementation of a Control Programme, carried out in 1979. The accumulated experience of 13 years works is presented in this study.


METHODS
The strategy used is that of the Primary Health Care; and community participation is a fundamental component of the programme as well as local planning and the approach of risk in the allocation of resources. The activities included the systematic dogs deparasitation with Praziquantel, carried out by health agents from the system rural hospitals (health promoters not professional staff); the surveillance of dogs rate of infection by means of diagnostic deparasitations made with hydrobromide or arecoline, educational talks at schools, the use of mass media, an the determination of ovine parasitism in studies carried out in the area abattoirs.


RESULTS
The information registered indicates that 1,86,156 dog deparasitations with Praziquantel were carried out with a consumption of 443,533 tablets and 11,178 deparasitations with hydrobromide and Arecoline. A continuous decrease of rates appears during the Period 1979-1992. So, dog Echinococcosis was reduced from 41.5% to 4.24% and ovine Hydatidosis from 61% to 12.7%. Consequently, Human Hydatidosis has decreased from an incidence rate of 64.11 x 100,000 in the age group of 0 to 10 years to and incidence rate of 4.46 x 100,000.


CONCLUSIONS
Finally, the results of the Programme are analyzed in the light of other global experiences of control; and the strategies that should be put into practice in the future with a view to a final limitation of the rate of transmission to man are analyzed.
