Climate change potential impacts on mosquito-borne diseases: a mathematical modelling analysis

Climate change and global warming have caused catastrophic effects that are already being felt in Bangladesh. The rise in temperature associated with global warming, as well as the broader impacts of climate change, are damaging the planet. These effects are spatial and temporal and have led to unexpected outcomes, such as the coexistence of humans and mosquitoes in regions where it was previously unimaginable. Despite being the smallest animals on earth, mosquitoes are also the deadliest, killing thousands of humans each year. The Culex mosquito, a common type of mosquito in Bangladesh, is easily accessible and poses a significant threat to human health. The transmission of viruses to humans is a significant concern. This article introduces and discusses the LMSEI-SEIR mathematical model, which can help in understanding this process. The disease-free equilibrium point and its stability are presented, and the reproduction number is calculated. To further investigate the implications of this model, a numerical analysis is conducted using MATLAB. The resulting figures can be used to inform future measures aimed at protecting against human fatalities.
