WHO warns of increased mosquito-borne diseases in Southern Europe

The World Health Organization (WHO) has issued a warning regarding a surge in mosquito-borne diseases across Southern Europe, particularly noting an increase in West Nile virus infections. Greece has confirmed 14 new cases in the past week alone, pushing its total for the year to 21. Of these, 13 individuals are currently hospitalized, with three in intensive care units, according to the Greek National Public Health Service.

Italy has also reported a significant number of cases, with 21 infections identified across 17 different regions. The WHO data indicates that single cases have also been detected in Spain, Romania, and North Macedonia. The West Nile virus primarily circulates between mosquitoes and birds, but infected mosquitoes can transmit the virus to humans through bites, typically from July to September.

Experts believe the actual number of infections may be higher, as many infected individuals are asymptomatic. Approximately one-fifth of those infected develop flu-like symptoms two to 14 days after exposure. In severe cases, the virus can lead to neurological diseases, including encephalitis and meningitis. There are no vaccines or specific treatments for the virus; medical care focuses on managing symptoms.

The WHO advises travelers to take precautions against mosquito bites, such as wearing appropriate clothing and using repellents. The organization notes that while the risk of severe illness is generally low for young people, longer and hotter summers increase the possibility of transmission. Individuals experiencing high fever, rash, or neck stiffness after a mosquito bite are urged to seek immediate medical attention.
