The occurrence of neuroinvasive symptoms caused by the West Nile virus at an emergency center
Introduction: According to the European Centre for Disease Prevention and Control, the prevalence of neuroinvasive symptoms caused by the West Nile virus (WNV) has significantly increased in the past years throughout Europe, including Hungary. The rise may be attributed to changes in precipitation and climate. The WNV zoonosis is spread by mosquitoes. It is mostly asymptomatic, flu-like symptoms occur in 20% of the cases and in less than 1% a neuroinvasive disease with a lethal outcome may develop. Aim: Our aim was to demonstrate the neuroinvasive symptomatology and the diagnosis and treatment of WNV infections by describing our patient cases as well as to resolve differential diagnostic dilemmas. Method: We report the cases of 4 patients treated at the "Moritz Kaposi" Somogy County Hospital between the 31st July and 4th September, 2018, with WNV, whose diagnoses were confirmed by serological and molecular biological methods. An epidemiological overview of WNV infections was also given. Results: Four patients were confirmed to have had WNV infection in the given time period. A wide range of neurological symptoms were observed in each patient and death occurred in one case. The patients were elderly with a number of comorbidities. Conclusions: The appearance of more severe, neuroinvasive symptoms following WNV infections is also characteristic of Hungary. The treatment of the infection is supportive, including giving pain relievers and the management of secondary infections. It is important to consider the possibility of a WNV infection in the case of a neurological disease of unknown origin, particularly if the symptoms indicate encephalitis.
