Synopsis
Europe grapples with unprecedented challenges from mosquito-borne diseases such as West Nile virus and chikungunya, as revealed in a recent ECDC report. Rising temperatures and environmental shifts contribute to these alarming trends, prompting urgent public health responses. Discover the implications and the urgent need for action in this evolving health landscape.
Key Takeaways
- Europe is seeing longer transmission seasons for mosquito-borne diseases.
- Environmental changes are contributing to the spread of these diseases.
- Chikungunya outbreaks have reached an all-time high in Europe.
- New cases of West Nile virus are being reported regularly.
- Effective prevention and control measures are urgently needed.
New Delhi, Aug 20 (NationPress) Europe is witnessing extended and more severe transmission periods for mosquito-borne ailments, such as West Nile virus (WNV) and chikungunya, as highlighted in a recent report from the European Centre for Disease Prevention and Control on Wednesday.
The report attributes this change to various climatic and environmental factors, including increased temperatures, prolonged summer months, mild winters, and shifts in precipitation patterns.
These elements come together to form an ideal habitat for mosquitoes, enhancing their ability to spread viruses.
“Europe is transitioning into a new era — where longer, broader, and more intense transmission of mosquito-borne diseases is becoming commonplace,” stated Pamela Rendi-Wagner, Director of ECDC.
“The ECDC is collaborating closely with all Member States to offer customized support and prompt public health recommendations to bolster Europe’s response,” she remarked.
The report indicated that the mosquito species capable of transmitting the chikungunya virus (Aedes albopictus) has now been identified in 16 European nations and 369 regions, a significant increase from just 114 regions a decade ago.
This proliferation, coupled with rising international travel, heightens the likelihood of local outbreaks.
As of 2025, Europe has recorded 27 outbreaks of chikungunya, setting a new continental record.
Remarkably, for the first time, a locally acquired case of chikungunya virus disease has been reported in France’s Alsace region — an unusual event for this latitude, underscoring the ongoing northward expansion of transmission risk.
Additionally, the spread of West Nile virus cases across Europe continues to evolve, with new infections reported annually over the last decade. This year has seen infections for the first time in the Italian provinces of Latina and Frosinone, as well as in Sălaj County in Romania.
Europe is also experiencing the highest number of West Nile virus cases in three years. ECDC anticipates that infections will continue to rise, likely peaking seasonally in August or September.
“As the landscape of mosquito-borne diseases changes, more individuals in Europe will face increased risks in the future. This underscores the critical need for prevention through both coordinated public health initiatives and personal protective measures. There is an urgent imperative to enhance and expand effective, eco-friendly mosquito control strategies,” stated Dr. Céline Gossner, Head of Section for Food-, Water-, Vector-borne and Zoonotic Diseases at ECDC.
Point of View
I believe the alarming rise in mosquito-borne diseases in Europe signals an urgent need for effective public health measures. The ECDC's findings underscore the importance of understanding climate impacts on health and the necessity for coordinated responses across nations. It is crucial that we prioritize prevention and control to safeguard our communities.
