Selected arboviral diseases imported to Poland – current state of knowledge and perspectives for research

Introduction Arthropod-borne viruses are important causes of human morbidity worldwide. However, the available literatur and the epidemiological data concerning the importation to Poland of globally emerging arboviral infections, such as DENV, CHIKV, WNV, or ZIKV, are scarce. Only few seroepidemiologic studies concerning WNV in animals or humans in Poland have been published. Objective The aim of this review paper is to summarize and present the current state of knowledge and the perspectives for research concerning the importation and the risk posed by the introduction to Poland of the four above-mentioned arboviral diseases. Current state of knowledge Climate change may facilitate the northward expansion of both the vectors for diseases previously unseen in Europe, as well as of the viruses themselves, resulting in autochthonous cases of diseases previously exclusively imported. Little is known about the importation of arboviral diseases to Poland because of the frequently asymptomatic or self-limiting course of the disease, lack of epidemiologic studies or effective disease reporting, as well as inadequate access to diagnostic methods. Conclusions Further epidemiologic studies in Polish travellers are necessary in order to prevent importation or introduction of the above-mentioned viruses, and to act against potential problems related to blood transfusion or organ transplantation from infected donors.
