More than 240 people across Europe have been confirmed to have contracted West Nile virus this year, with Italy and Greece accounting for the majority of reported cases.
According to a weekly report by the European Centre for Disease Prevention and Control (ECDC), 241 human infections have been recorded since the start of the transmission season through Wednesday.
Italy reported the highest number at 139 cases, followed by Greece with 61. Spain recorded 17 cases, North Macedonia 13, Romania 6, France 4 and Germany 1.
The rise in infections comes after the World Health Organisation (WHO) called for increased vigilance last month following several cases of West Nile fever in southern Europe.
The virus is mainly transmitted between mosquitoes and birds, but infected mosquitoes can also spread it to humans. Transmission typically occurs between July and September, making the summer months a key period for monitoring infections.
While most infected people show no symptoms and may not know they have contracted the virus, Germany’s Robert Koch Institute said this could mean many infections go unreported.
In severe cases, however, the virus can affect the nervous system and lead to conditions such as encephalitis and meningitis.
There is currently no vaccine or specific cure for West Nile disease, with treatment focused on managing symptoms. To reduce the risk of infection, the WHO advises people to avoid mosquito bites by wearing suitable clothing and using insect repellent.
