Croatia: West Nile virus cases reported

Event

Local authorities have reported mosquito-transmitted cases of the West Nile virus, predominately in the northwest and east of the country. A total of 26 people have reportedly contracted the disease in 2018 as of September 3, and one person has died. Officials are advising residents to take precautions to prevent mosquito bites.

Context

West Nile virus is a disease most commonly transmitted by mosquitoes. The majority of infected people exhibit no symptoms, but it is estimated that 20 percent exhibit some symptoms and 1 percent develop severe neurological infections such as encephalitis and meningitis, certain effects of which can be permanent. The US-based Centers for Disease Control notes that people over 50 have an increased risk of developing severe symptoms.

Advice

Individuals in Croatia are advised to take measures to protect themselves from mosquito bites - e.g. by wearing covering clothing, using insect repellent, and sleeping in an air conditioned room - and to eliminate possible mosquito breeding grounds in and around their residences (small pockets of fresh water, such as rain water that has collected in cans, bottles, tires, flower pots, clogged gutters, etc.). Individuals exhibiting symptoms of serious infection should seek medical attention.
