Objectives: Cystic echinococcosis (CE) remains an endemic parasitosis worldwide, with Greece traditionally considered as one of the endemic European countries. We sought to evaluate prevalence trends of CE in a hyper-endemic for zoonoses area of Central Greece, as detected through abdominal ultrasound.

Methods: Abdominal ultrasound records of patients tested at the Radiology Department of the General Hospital of Trikala, Thessaly, in Central Greece, for the period 2001–2008 were evaluated. The presence of simple hepatic cysts and liver haemangiomas was studied in parallel.

Results: Of the 47045 total ultrasound tests performed in the period 2001–2008, a total of 189 tests revealed abdominal hydatid disease, representing 153 individuals with cystic echinococcosis, indicating prevalence below 4 per 1000. Prevalence of haemangiomas reached 5 per 1000, and that of simple hepatic cysts 13 per 1000. Dividing the study period in two sub-periods (2001–2004 and 2005–2008), a statistically significant trend towards decreasing annual incidence was noted for abdominal CE.

Conclusion: The prefecture of Thessaly in Central Greece is hyper-endemic for numerous zoonoses, CE included, due to its population characteristics (rural orientation, agricultural basis of the economy). Despite a generally high prevalence, a statistically significant decreasing trend in annual incidence was noted during the second half of the study period. In conclusion, the implementation of a national campaign for control of cystic echinococcal disease in both animals and human (started in Greece in 1984), has led to decreasing annual detection rates of CE in Central Greece.
