Greece, West Nile alert: 157 cases and 13 deaths this summer

Greece is facing a significant rise in West Nile virus infections, prompting health authorities to issue an alert. Since the beginning of the year, 157 infections and 13 deaths have been confirmed, with the majority of cases recorded in the greater Athens area. The virus continues to circulate across several countries in southern Europe.

Symptoms and severe forms

According to available information, most infected individuals show no symptoms or experience only mild illness without complications. However, severe cases do occur, in which the disease progresses to encephalitis or meningitis — forms that can be life-threatening. For this reason, health surveillance has been stepped up, particularly in areas with large mosquito populations.

Warning signs that require urgent medical attention, especially following a mosquito bite:

• high fever
• headache
• stiff neck
• confusion or disorientation
• muscle weakness

What is West Nile virus and how is it transmitted

West Nile is a virus transmitted to humans primarily through the bite of an infected mosquito. Approximately 80% of people who become infected develop no symptoms whatsoever.

Protective measures

To reduce the risk of infection, authorities recommend:

• using mosquito repellent products
• wearing clothing that covers the arms and legs
• using mosquito nets
• eliminating standing water around the home, where mosquitoes can breed

There is currently no vaccine for humans and no specific antiviral treatment for this disease. People who develop severe forms of the illness require hospitalisation and supportive care, which may include intravenous fluids and, in serious cases, respiratory support.
