EODY Warns: Protect Yourself from Mosquitoes to Prevent West Nile Virus

The National Organization for Public Health (EODY) advises the public to take preventive measures against mosquitoes to reduce the risk of contracting the West Nile Virus, which is expected to appear in the coming months. As noted by EODY, cases of West Nile Virus infection are recorded annually in many countries worldwide, including several European nations, typically during the summer and autumn months. Since 2010, cases have been reported almost every year in Greece as well. Over the past 15 years (2010–2024), a total of 2,088 local cases of West Nile Virus infection have been recorded in Greece, with an average annual number of 145 cases. Of these, 1,471 (70%) involved central nervous system manifestations, and there have been a total of 292 deaths among infected patients. In 2024 alone, 220 local cases were recorded in Greece, including 157 with central nervous system involvement and 35 fatalities. Based on historical epidemiological data, the reappearance of cases during the current mosquito season (2025) is anticipated. Therefore, EODY has already informed healthcare professionals nationwide about the need for vigilance regarding the disease during this period. The West Nile Virus is primarily transmitted through the bites of infected common mosquitoes, which become infected after feeding on infected birds. While most people who contract the virus do not fall ill or exhibit only mild symptoms, a small percentage develop severe neurological diseases such as encephalitis or meningitis. Individuals over 50 years old, those with weakened immune systems, or chronic underlying conditions are at higher risk of developing serious complications. To protect against mosquitoes, EODY recommends using approved insect repellents, wearing long clothing, using bed nets, and avoiding stagnant water. Special attention should be given to vulnerable groups. EODY conducts enhanced epidemiological surveillance and collaborates closely with national authorities and local governments to manage the spread of the virus effectively.
