Objective: The north part of Croatia, especially the Koprivnica-Krizevci County is a well known endemic area of several tick-transmitted diseases including tick-borne encephalitis, Lyme borreliosis and tularemia. Each summer numerous patients develop a nonspecific febrile illness after tick bite, etiology of which is sometimes never established.
Purpose Of Work: The aim of this prospective study was to determine whether the infection with Anaplasma phagocytophilum was associated with febrile illnesses occurring after tick bite.
