World Mosquito Day: The growing threat of mosquito-borne diseases in a warming world

Every year on August 20, World Mosquito Day presents an opportunity to raise awareness of the burden of mosquito-borne diseases and highlight ongoing efforts to fight the world’s deadliest creature. While mosquitoes may seem like mere nuisances remaining mostly invisible in our everyday lives, their role as vectors for some of the world’s most lethal diseases makes them responsible for hundreds of thousands of deaths every year.

In recent years, the fight against mosquito-borne diseases has become increasingly urgent. 2024 has been the worst year for dengue cases on record. As of July, over 10 million cases of dengue had been reported from 176 countries. Meanwhile, malaria remains a persistent threat; according to the 2023 World Malaria Report, in 2022 alone, there were an estimated 249 million malaria cases, including 608,000 deaths. Most of these are children under the age of five.

The numbers are staggering, and there are further challenges ahead. Climate change could expose nearly half a billion more people to mosquito-borne diseases such as yellow fever, Zika, dengue and chikungunya by 2050. Warmer temperatures and increased rainfall create ideal conditions for mosquito vectors to breed, proliferate and transmit diseases. For instance, widespread flooding which hit Pakistan in 2022 resulted in a five-fold surge in malaria cases across the country. The once-clear battle lines are shifting, and we must adapt to this new reality. 

To celebrate World Mosquito Day this year, the Outreach Network for Gene Drive Research is conducting a social media campaign featuring facts about mosquitoes, the diseases they transmit and ongoing efforts to control mosquito-borne diseases such as malaria and dengue. The Network is spotlighting 15 researchers and experts who are working on innovative approaches to step up the fight against mosquito-borne diseases amidst growing challenges.  

On World Mosquito Day, we are reminded that the fight against these tiny, yet mighty adversaries, is far from over. This day is not just a day to reflect; it should serve as a call to action, a reminder that the fight against mosquito-borne diseases will require efforts from every corner of the globe.
