West Nile virus cases rise in Cyprus

As of September 2, 2026, health authorities in Cyprus have confirmed six cases of the West Nile virus, with two additional suspected cases currently undergoing laboratory testing. The cases, which emerged over the summer, represent an increase compared to previous years according to infectious disease expert Aristos Aristodemou, although officials initially characterized the situation as under control. Unlike prior local outbreaks, none of the patients reported any recent travel history, confirming local transmission through mosquitoes.

Approximately 80% of infections remain asymptomatic, while about 20% of patients experience flu-like symptoms. Notably, Philenews reports that all six confirmed patients required hospitalization, a detail that contrasts with earlier government statements suggesting the situation was stable due to a perceived lack of severe cases. Only about 1% of cases, primarily involving elderly or immunocompromised individuals, are expected to develop severe neuroinvasive disease.

Health experts remain in a state of high readiness as they continue to monitor the situation. While the virus cannot be transmitted directly between humans or from humans to mosquitoes, authorities are closely tracking potential new infections. Further laboratory results for the two pending cases are expected soon to determine if the official count will rise further.
