Methods: From the provinces of Erzurum, Kars, Ardahan, Iğdır, Ağrı and Erzincan in the Eastern Anatolia Region, Turkey in August-September 2017, blood samples were provided from 305 participants (volunteer patients and their relatives), including 151 females (49.50%), whose ages ranged between 6-85 yr and were diagnosed as Alveolar echinococcosis (AE) and operated in concerned clinics.  Results: EIgG ELISA was determined as positive in 29 (9.5%) participants, including 17 (11.3%) females and 12 (7.8%) males. In addition, Em2-Em18 ELISA was also determined as positive in 15 (4.9%) participants, including 9 (6%) females and 6 (3.9%) males. Tweleve (3.94 %) of these findings were observed as positive in terms of both tests. Through the verification done by Anti-EWB IgG, Echinococcus multilocularis (EM) was identified in 7 (21.9%) of the female participants, E. granulosus (EG) in 1 (3.1%), and both parasites in 2 (6.2%). For male participants, EM was determined in 3 (9.3%) of them, EG in 1 (3.1%), and both parasites in 1 (3.1%). Conclusion: AE continues to threaten public health in the region. In families where AE is detected positive, the reason for disease is based on nutrition; thus, it will be proper to check up all family members in the terms of infection. https://ijpa.tums.ac.ir/index.php/ijpa/article/view/3654 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/3654/1255
