Climate change is creating ‘more favourable conditions’ in Europe for invasive tiger mosquitoes, leading to a significant rise in dengue fever cases across the continent, experts warn. The European Centre for Disease Prevention and Control (ECDC) has issued a warning about the surge in dengue fever cases, possibly linked to the presence of the invasive species.
The tiger mosquito, an invasive species originally found in tropical countries, has now established its presence in 13 European Union countries, including France, Spain, and Greece. According to the ECDC, the rising temperatures brought about by climate change are contributing to the favorable conditions for the spread of these mosquitoes in Europe. Furthermore, the ECDC has raised concerns about the likelihood of further increases in dengue fever cases in the upcoming years.
The ECDC noted that the number of locally acquired dengue fever cases in the EU rose sharply in 2023, with 130 reported cases compared to 71 in 2022. The increase is even more significant when compared to the period between 2010 and 2021 when there were only 73 cases reported.
With the Olympic Games set to take place in Paris at the end of July, authorities in the city have been actively monitoring and trapping the invasive mosquitoes, indicating the growing concern regarding the potential impact of dengue fever outbreaks in densely populated areas. The ECDC has also emphasized the potential risk of increased outbreaks in Europe due to international travel and the expansion of suitable habitats for these invasive species. To mitigate the risk, the ECDC has advised individuals to remove stagnant water from their gardens or balconies, as these are potential breeding grounds for mosquitoes, and to use repellents as well as screens on windows and doors to minimize exposure.
The widespread presence of the tiger mosquito in Europe and the subsequent surge in dengue fever cases highlight the urgent need for proactive measures to control the spread of invasive species and prevent the associated health risks. As climate change continues to shape the environment, the impact on disease transmission and the expansion of invasive species underscores the importance of coordinated efforts to address these emerging challenges in public health and environmental management.
