First 2026 West Nile virus case reported in Cyprus

Cypriot health authorities have confirmed the first case of West Nile virus (WNV) on the island for 2026. A 74-year-old man, who had no recent travel history, was admitted to the Nicosia General Hospital on August 12. His condition deteriorated on August 14, requiring intubation and treatment in the intensive care unit for encephalitis. Medical officials state that while he remains in serious condition, he is currently showing signs of clinical improvement.

Simultaneously, the State Health Services Organisation (OKYPY) confirmed that two cases of dengue fever were recorded in Cyprus last July. Both patients—a woman who had traveled abroad and a healthcare professional who came into contact with her blood—have since recovered and been discharged. Authorities emphasize that while WNV is endemic to the region and occurs sporadically, there is no cause for public alarm or expectation of an outbreak. Cyprus is currently developing a specialized surveillance mechanism for mosquitoes, as it is the only country in the region lacking such a formal system. Health services have initiated localized vector control measures, including spraying and habitat destruction around the area where the WNV patient resides.
