Hotter Earth, Sicker World: The Surge of Insect-Related Diseases
Climate change is making it easier for diseases spread by insects, like mosquitoes and ticks, to affect more people around the world. As temperatures rise and weather patterns change, these insects can live in more places and for longer periods. Now we’re seeing a surrge of insect-related diseases.
What Are Insect-Related Diseases?
Insect-related, known as vector-borne, diseases are are illnesses transmitted to humans through carriers like mosquitoes and ticks. These carriers, or “vectors,” pick up harmful germs from one host and pass them to another. Examples include:
These diseases are responsible for over 700,000 deaths each year and make up more than 17% of all infectious diseases globally. If current trends continue, up to 8.4 billion people could be at risk of diseases like malaria and dengue by the end of the century.
Now we can add one you’ve probably never heard of–Babesiosis. It’s becoming more common in the U.S. because it is rapidly expanding through the mid-Atlantic.
Babesiosis is spread by the same tick that causes Lyme Disease and has similar symptoms to malaria, like fever, chills, headache, and fatigue.
How Climate Change Increases Insect-Related Disease Risk
Climate change affects vector-borne diseases in several ways:
Expanding Habitats: Warmer temperatures allow mosquitos and ticks to survive in new areas, including places that were previously too cold for them.
Longer Seasons: Milder winters and earlier springs mean these insects are active for more months each year, giving them more time to spread diseases.
More Breeding Grounds: Increased rainfall leads to more standing water, which acts as a breeding ground for mosquitos.
What Can Be Done?
To reduce the risk of vector-borne diseases, we can:
Control Vectors: Use insecticides and eliminate standing water to reduce mosquito and tick populations.
Monitor and Predict: Employ digital tools and climate data to forecast disease outbreaks and prepare accordingly.
- Adapt Health Systems: Strengthen healthcare infrastructure to respond quickly to emerging disease threats.
Addressing climate change by reducing greenhouse gas emissions is also crucial to limit the spread of these diseases in the long term.
