As global temperatures rise and climate change accelerates, mosquito-borne diseases are becoming a growing threat to public health around the world. According to Avijit Das, R&D Director, Global Pest Control Innovation at Reckitt Benckiser, mosquito breeding seasons are extending and the insects are appearing in regions where they were previously uncommon. Diseases like dengue fever and Zika virus are becoming increasingly prevalent in Europe and other areas outside of their traditional hotspots in sub-Saharan Africa, Southeast Asia, and Latin America.
The link between climate change and the spread of mosquito-borne diseases is multifaceted. Rising temperatures and changes in environmental conditions are extending the breeding season of mosquitoes, while droughts and changes in land use can create new breeding sites. Additionally, human migration to urban areas is increasing the risk of outbreaks.
According to the Early Warning System for Mosquito-Borne Diseases (EYWA), malaria cases in Europe have increased by 62%, and cases of dengue, Zika, and chikungunya have risen by 700%. The World Health Organization (WHO) has emphasized the need to re-evaluate tools for disease prevention and response and to equip personnel and communities with evidence-based practices.
Das stressed the importance of monitoring the changing trends in mosquito-borne diseases in order to respond effectively. His lab in Gurugram, India, tracks mosquito populations, diseases, and evolution. Through research and innovation, it may be possible to find new solutions to this growing public health threat.
In conclusion, the impact of climate change on mosquito-borne diseases is a serious concern that requires immediate attention. While the situation may seem dire, with the right tools, knowledge, and resources, it is possible to address this threat and protect public health around the world.
