Project
In recent years, an enormous rise in the incidence of infections caused by arboviruses, characteristically spread by arthropods, has been recognized worldwide. West Nile virus (WNV) is a mosquito-borne flavivirus, causing the disease West Nile fever. The spectrum of clinical presentation is from asymptomatic disease, to disease with only flu-like symptoms, to fatal neuroinvasive disease. In the year 2018, a rapid increase of human WNV cases was observed in Europe and in year 2019, the first symptomatic human case was diagnosed in Slovakia. Factors which are responsible for global change of the environment (as urbanisation, increasing human population, climate change, etc.) are hypothetically linked to the re-emergence of arboviral infections. But, can this changed environment provide a more suitable and a supportive habitat for arbovirus circulation? The aim of our project is to verify the hypothesis that the influence of global change is a driver of a WNV re-emergence, based on environmental conditions.
