West Nile Virus Cases Surge in Greece; Vulnerable Groups Identified

Greece is experiencing a significant increase in West Nile virus cases this year, with health officials urging public caution as the transmission season has not yet concluded.

According to the Hellenic National Public Health Organization (EODY), 157 infections have been documented so far. Of these, 116 individuals developed severe central nervous system complications, the most serious form of the disease. Tragically, 13 deaths have been attributed to the virus. The deceased patients ranged from 66 to 91 years old, with an average age of 82, and most had significant underlying health issues.

The severe cases primarily affect adults between 19 and 99 years old, with the average age of those experiencing neurological complications being 74. Notably, no children have been reported among those with severe neurological issues.

Recent research published in JAMA sheds light on groups particularly vulnerable to severe West Nile virus infection. A 12-year data analysis indicates that individuals with conditions such as multiple sclerosis, alcohol-related disorders, compromised immune systems due to immunosuppressive therapy, hematological malignancies, a history of stroke, chronic kidney disease, and hypertension face a greater risk of developing severe illness and neurological complications. The study also suggests men may be at a higher risk than women.
