Problems in Anti-epidemic Control of Brucellosis in Bulgaria
Journal Title: Macedonian Journal of Medical Sciences (MJMS) - Year 2010, Vol 3, Issue 3
Abstract
Aim. To elucidate the distribution of brucellosis among humans in Bulgaria for the period 1950-2007 and to evaluate the official measures regarding brucellosis elimination. Methods. We used data from the official registry of infectious diseases, survey data on epidemiological control, and data from epidemiological and epizootical surveys. Results. Registered morbidity of brucellosis in Bulgaria varied between 0.01 cases (1959, 1974, 1985, 1993, 1996, 2000) up to 0.048 (2005) and 0.74 (2007) per 100,000 inhabitants. No cases of human brucellosis were recorded in Bulgaria for 35 years of the entire study period from 1950 to 2007. The periods without registered cases of brucellosis initially lasted about 7-10 years and later 2-5 years. Two deaths were recorded for the years 1958 and 2005. Of the 28 regions in the country, 17 (61%) were affected during multiple years between 1991 and 2007: Plovdiv for 4 years; and Varna, Ruse, Pazardjik, Yambol and Burgas for 2 years. The remaining 11 regions (39%) were affected in only one year during the same period. In all cases professional exposure or consumption of uncooked milk or milk products was identified as a risk factor. The infections persisted from months to years. Conclusion. Anti-epidemic measures taken by health-care authorities implemented in collaboration with veterinary services can restrict the distribution of human brucellosis.
