Croatia is battling a surge in West Nile fever cases carried by mosquitoes. The capital city of Zagreb has initiated widespread fumigation following seven confirmed infections. The European Centre for Disease Prevention and Control (ECDC) reports over one thousand cases across Europe, with the potential for further increases before winter. Authorities in Croatia are working to eliminate the mosquito population and curb the spread of the disease. The fumigation is a major step to protect public health in Zagreb and surrounding areas. The ECDC warns of a continuing risk throughout the continent as the mosquito season progresses.
