| Abstract |
| Climate change is increasingly recognized as a major driver of emerging and re-emerging viral diseases. Shifts in temperature, humidity, rainfall, and extreme weather events directly affect virus survival, transmission dynamics, and host–vector interactions. Warming temperatures can expand the geographical range of vectors such as mosquitoes and ticks, leading to the introduction of viral pathogens into previously unaffected regions. Changes in precipitation and humidity influence viral persistence in the environment and the likelihood of outbreaks, while heat stress and altered nutrition may compromise host immunity, increasing susceptibility to infection. Furthermore, climate-driven disruptions in ecosystems and agricultural practices can facilitate cross-species transmission and accelerate viral evolution. This presentation explores the multifaceted relationship between viral infectivity and climatic change, highlighting recent evidence from both plant and animal viruses. Understanding these links is crucial for predicting disease risks, developing effective surveillance systems, and designing adaptive strategies to mitigate the impact of climate change on global health besides food security. |
