Across Europe, health authorities and public reports indicate that mosquito season is entering its peak months, raising the risk of mosquito-borne illnesses. Several outlets cite increased concern about viruses including West Nile virus and chikungunya, with additional mention of dengue fever as a potential threat. The articles specifically point to popular holiday destinations such as Spain, France and Italy as places where these mosquito-borne diseases are present or under monitoring.

The coverage frames the development as part of broader seasonal patterns: rising mosquito activity can increase the likelihood of virus transmission in regions where mosquitoes capable of spreading these infections are present. The reports do not provide detailed case counts in the excerpts provided, but they emphasize that travellers and residents may face heightened exposure during summer.

Overall, the sources converge on the same timing and risk theme—peak mosquito months in Europe—while highlighting West Nile virus and chikungunya as notable concerns, with dengue also mentioned as a possible mosquito-borne disease affecting the continent.
