The LWNVIVAT project is dedicated to finding preventive and treatment options for West Nile Fever (WNF), a disease caused by the West Nile Virus (WNV) that continues to be monitored closely in both the United States and Europe. This year, we’ve seen an increase in reported cases, which underscores the importance of research and preparedness.

In the United States, there have been 1,410 reported human cases of WNV infection in 2024. Of these, 1,018 cases have been classified as neuroinvasive, meaning they affect the nervous system. WNV human infections have been reported in 49 states this year, which highlights the need for ongoing attention to public health and safety.

In Europe, 19 countries have reported a total of 1,436 cases of WNV and 125 associated deaths as of December 4, 2024. The virus has been observed in new areas, including Albania, Kosovo, and Slovakia, indicating a broadening of its geographical range. This year, 212 regions across Europe have reported cases, the largest spread observed in recent years.
As in previous years, most reported cases occur in men over 65 years of age. Severity indicators remain consistent with past years, with 91% of cases requiring hospitalization, a case fatality rate of 9%, and neurological manifestations present in 68% of cases. The high rate of neurological cases is expected, as those with more severe symptoms are more likely to be diagnosed.
The need for action
The growing number of WNV infection cases reinforces the importance of continued research and prevention. As the virus spreads to more regions, it becomes increasingly important to focus on developing both preventive measures and effective treatments. The LWNVIVAT project is playing a key role in this effort by exploring new ways to protect individuals and improve health outcomes for those affected by WNV.
Although the increase in cases is noteworthy, it is also important to recognize the progress being made in understanding and addressing WNV. With ongoing research, including the efforts of the LWNVIVAT project, we are working to ensure that effective treatments and prevention strategies are available when needed.
