Global warming is enabling the spread of diseases like dengue and cholera while disrupting vaccine effectiveness and distribution, experts say.
Kiley Price reports for Inside Climate News.
In short:
- Rising temperatures and extreme weather fuel the spread of diseases such as dengue fever and cholera by creating conditions for bacteria and mosquitoes to thrive.
- Climate change damages vaccine infrastructure, with heat and humidity degrading supplies and extreme events impeding distribution.
- Vaccine hesitancy, worsened by misinformation and political rhetoric, undermines immunization efforts at a time when they are more critical than ever.
Key quote:
“Vaccine hesitancy and climate change denialism are two faces of the same ugly coin.”
— Alessandro Siani, University of Portsmouth researcher
Why this matters:
Global health faces a dual threat as climate change accelerates the spread of infectious diseases while also complicating prevention and treatment. Addressing misinformation and bolstering vaccine systems are critical to safeguarding vulnerable populations.
