Echinococcosis in children and adolescents in Bulgaria: a comparative study.

Between 1971 and 1995, 5874 patients underwent surgery in Bulgaria because of cystic echinococcosis caused by Echinococcus granulosus. Of these 5874, 10.6% were children aged < 15 years and 5.25% adolescents aged 15-19 years, giving annual incidences of 1.25 and 2.03/100,000 inhabitants, respectively. Although the annual incidence of surgery for echinococcosis among adults (3.12/100,000) was higher than the combined value for children and adolescents (1.48/100,000), the data indicate that most human infections with E. granulosus occur during childhood and adolescence. In evaluating the epidemiology of echinococcosis or the effectiveness of a control programme, therefore, reductions or increases in the incidence of clinical disease among children and adolescents indicate an improving or worsening situation, respectively. The incidence of surgical treatment for echinococcosis was higher in males than females in all but the youngest subjects (< 5 years) and adults (> 19 years). It was also higher in rural populations than in urban populations, particularly among children and adolescents. Whereas cysts were found more frequently in the lungs of children and adolescents than their livers (51.8% v. 38.3% of the patients), most cysts found in the adults were hepatic (73.5% of patients) and relatively few were in the lungs (14.4% of patients).

Human echinococcosis in Bulgaria: a comparative epidemiological analysis.

The present article describes the importance of human echinococcosis as a public health problem in Bulgaria, outlines the control measures carried out and evaluates comparatively the situation over three periods spanning 46 years (1950-1995). During the first period (1950-62), a total of 6469 new surgically confirmed cases of hydatid disease were recorded in Bulgaria, with an annual incidence of 6.5 per 100,000 population, and the infestation rate in domestic animals and dogs was high. Echinococcosis was endemic throughout the country. The organization of a control campaign, initiated in 1960, led to a considerable improvement in the situation during the second period (1971-82). Morbidity among humans gradually decreased, with an average incidence of 2.0 per 100,000, and the proportion of infected animals also fell. The distribution of echinococcosis was characterized as sporadic or of low endemicity. During the third period (1983-95), owing to administrative irregularities and economic changes, funds for supporting the campaign were reduced and control structures were dismantled. As a result, the incidence rose to 3.3 per 100,000. Echinococcosis again became endemic, in some regions hyperendemic. The findings provide convincing evidence that cessation of control measures or reduction of campaign activity can lead to intensification in the transmission of Echinococcus granulosus and to a resurgence in echinococcosis to previous levels.

[Epidemiology of echinococcosis in domestic animals and man in Bulgaria].

Echinococcosis is an important agricultural and public health problem in the People's Republic of Bulgaria. Organized and purposeful control since 1960 has proved to be effective. In the investigated period from 1975 to 1979 a decreased infestation with Echinococcus granulosus of man and farm animals could be observed. Infestation degree of sheep is below 20% in flat areas, whereas in mountainous regions it is well over 50%. The infestation of the population with echinococcosis is not equally distributed. It varies between 0.7 and 5.77 in 100,000 persons in different areas. The most common sources of infection are "domestic" dogs (57.76%), followed by hunting dogs (28.58%) and herding dogs (13.56%).
