title: West Nile virus and USUTU--a threat to Poland.
abstract: In recent years emergence of new infectious diseases and the growing spread of pathogens to new areas is observed. Most of these pathogens are zoonotic viruses and their transmission route is from animals to humans and vice versa. These so called emerging and re-emerging pathogens that were present previously only in Africa and Asia are becoming a threat to European countries. These include, e.g. West Nile virus and USUTU virus. The aim of the study is to present the clinical course of infections caused by WVN and USUTU, diagnostic and therapeutic possibilities and, above all, the current epidemiological situation of these infections in the world. We also tried to answer the question whether, there is a risk of infection with these viruses in Poland. After analyzing the available literature we venture a conclusion that in Poland there is a risk of WNV and USUTU infection. Global warming, change of socio-economic conditions, travelling greatly affect the spread of these viruses. In addition there are confirmed human cases of these diseases in countries neighboring Poland, as well as presence of both viruses and the presence of vectors (Culex pipiens sl and Culex torrentium (Diptera: Culicidae)) in our country. All these facts indicate that there is a necessity of epidemiological studies and consideration of these pathogens in the differential diagnosis of febrile illness and neuroinfection.
