Greece has recorded four new cases of West Nile virus infection between October 23 and 29, bringing the total number of confirmed infections this year to 457, while the death toll linked to the virus has reached 51, according to the country's National Public Health Organization (EODY).

The latest weekly surveillance report showed that no additional fatalities were reported during the past week, leaving the total number of virus-related deaths at 51 since the beginning of 2026. Health authorities also said nine patients remain in intensive care units receiving treatment for severe infections.

The four newly confirmed infections raised Greece's cumulative case count to 457 as of October 29, with public health officials continuing to monitor the seasonal spread of the mosquito-borne disease.

Health authorities urge continued vigilance

EODY stressed that although mosquito activity has declined in many parts of the country with the arrival of cooler weather, the risk of infection has not completely disappeared. The agency urged the public—particularly older adults, people with weakened immune systems and those with chronic illnesses—to continue taking precautions against mosquito bites.

According to European health surveillance data, Greece remains the second-most affected country in Europe this year after Italy in terms of reported West Nile virus infections.

West Nile virus is primarily transmitted through the bites of infected mosquitoes. While most infected individuals experience mild symptoms or none at all, the virus can cause serious neurological complications, particularly among elderly people and those with underlying health conditions.(ILKHA)
