The National Public Health Organization’s weekly report aims to offer a succinct summary of recorded West Nile Virus infections during the 2024 transmission season in Greece. Data is collected from healthcare providers and labs engaged in virus detection. The Monitoring of Vector-Borne Diseases Department conducts investigations of reported cases within 24 hours to assess exposure sites, disease traits, and risk factors. Patient outcomes are monitored throughout hospitalization.
2024 Case Statistics
Since the onset of the 2024 season, 100 domestic cases have been diagnosed, with 76 presenting with symptoms affecting the central nervous system, including encephalitis or meningitis. Additionally, 24 cases showed mild or no CNS symptoms. Recently, Albania reported three imported cases. There have been 12 deaths, with a median age of 83.
The report details the distribution of cases across Greek municipalities, highlighting areas of active virus transmission. One case of CNS involvement is estimated to relate to 140 mild or asymptomatic infections.
Public Health Measures
The National Public Health Organization has implemented ongoing surveillance since 2010 to prompt timely preventive actions. A partnership with the Ministry of Health has resulted in a comprehensive action plan released in March 2024 detailing standardized response actions. Key preventive measures include:
- Enhanced Surveillance and Communication
- Regular updates and alerts to health professionals and public officials.
- Investigation of suspected and confirmed cases within 24 hours.
- Public Awareness and Education
- Press releases and educational materials are distributed to the public and local authorities.
- Blood Safety Measures
- Identification of high-risk areas to ensure blood safety in affected regions.
International Context and Surveillance
Between January and August 2024, neighbouring European countries, including Italy and Spain, have reported West Nile Virus cases. Continuous monitoring and cross-border communication are vital for managing disease spread.
Despite rigorous measures, predicting areas for potential outbreaks remains challenging. With the virus embedded regionally, public health vigilance and protective steps against mosquitoes are essential. The National Public Health Organization continues to enhance surveillance and response protocols to minimize future impacts.
