Beginning with the register of human hydatidosis cases, kept by hydatidosis struggle programs of Rio Negro Province, was done the serologic longitudinal follow-up in patients operated on in the period 1980-1987, in the influence area of Ingeniero Jacobacci, Rio Negro, Argentina. The local Supervision Program obtained blood samples of 36 patients during 1990 (59% of them were operated on in the considered period), five patients died corresponding the remaining to persons to whom did not live in Ingeniero Jacobacci or to whom were not possible to evaluate. The blood samples were studied by DD5, confirming the disease immunologically in 18 cases (50%). In this work are evaluated possible causes of reinfection: surgery technic, individual susceptibility, immunological factors.

[Control of hydatidosis in the Province of Rio Negro, Argentina: epidemiology].

In this paper we attempt to present a general view of the situation of hydatidosis in the Province of Rio Negro, Argentina, considering the magnitude of infection in man and dog. Because of its seriousness a 10 year program for the control of hydatidosis has been carried out, which included veterinary and medical care. The number of human cases with hydatidosis in the period 1981-1988 was determined by a retrospective study of the registers of Public Health. From 1188 cases registered in the period, the annual numbers varied between 152 in 1981 and 104 in 1988. This implies an incidence rate of 40 x 100,000. The most frequent localization observed was in the liver. The average days of hospitalization has decreased to 15.8 per patient. Screening seroepidemiological surveys using DD5 allowed us to determine that the prevalence rate was in some departments of 2330 x 100,000. Also included are the results, up to now, of 10 years of field work done in the program area.

[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.

[Hydatidosis control in the province of Río Negro, Argentina: development of primary care programs].

Hydatidosis is a serious Public Health problem in the Province of Río Negro, Argentina. This situation has promoted the implementation of a control programme based on the canine systematic deparasitation with Praziquantel, health education, work control and care of persons. The accumulated experience of 15 years works, carried out to develop the last work--line mentioned above, is presented in this study. The activities includes the registry of human cases, the early identification of asymptomatic carries, the infected persons derivation to the hospital system in order to allow their appropriate treatment, the longitudinal follow up of the operated cases and the epidemiologic surveillance of the human hydatidosis situation. A network of laboratories was organized, as a support to satisfy the hospital demand, under the coordination of a central laboratory of reference and serologic surveys, among the groups at risk, were also carried out. The information registered indicates that a total of 60,078 serologic tests were carried out in the whole Province: out of them, 22,899 corresponded to hospital demand (DD5) and 37,179 to serologic surveys (originally latex, then DD5, and now Elisa). 65% of the cases, diagnosed by official register, is derived from rural areas to complexity hospitals, to be put under surgical treatment, and, out of these operated persons, only 3.9% is derived from the appearance of clinical symptomatology. A sustained reduction in the average days of stay, in lethality and in the rate of serologic prevalence in school children from 7 to 13 years of age, are achieved.(ABSTRACT TRUNCATED AT 250 WORDS)
