As the world recovers from the devastating Covid-19 pandemic, leading Chinese infectious disease expert, Zhang Wenhong, is already focusing on the next global health threat. Zhang, renowned for his role in leading Shanghai’s clinical expert team for COVID-19, is now addressing the critical intersection between climate change and infectious diseases.

Zhang has published extensively on public health and infectious diseases. His latest initiative highlights the indirect impact of Climate change on pathogen mutation and spread. As the planet warms, especially in subtropical regions, the habitats for pathogens and their vectors, like mosquitoes and ticks, expand. This increased range exposes more animals and humans to bacterial, viral, and fungal infections.
Research published in the Journal of Geophysical Research: Atmospheres indicates that ocean surface warming is expanding the tropics, creating new habitats for these pathogens. Consequently, diseases such as dengue fever and Lyme disease are appearing in regions previously unaffected. For instance, China is now detecting dengue fever in the Yangtze River Basin, a shift from its traditional southern confines.
Zhang warns that the future spread of vector-borne diseases like malaria will be influenced by changing global temperatures and precipitation patterns. This is supported by the World Health Organization (WHO), which predicts that Climate change will significantly alter disease distribution. Additionally, the COVID-19 pandemic, believed to have spread from bats, highlights how habitat changes can facilitate pathogen transfer to humans.
To combat these emerging threats, Zhang is collaborating with the University of Hong Kong (HKU) and other experts in Climate change, public health, and infectious disease control. Their goal is to develop comprehensive strategies for global pandemic preparedness. This includes establishing regular monitoring systems and enhancing data sharing among scientists worldwide.
Zhang emphasizes the need for a One Health approach, integrating efforts across various sectors to tackle global health threats. This initiative, backed by the WHO, aims to mobilize researchers, healthcare professionals, and policymakers to work collaboratively.
As part of these efforts, Zhang and his team are also addressing antimicrobial resistance, a growing concern exacerbated by Climate change. The emergence of drug-resistant pathogens poses a significant challenge, with projections indicating that by 2050, 10 million people could die annually from drug-resistant infections.
The work being done today by Zhang and his colleagues is crucial for early detection and response to future pandemics. By understanding the complex relationship between climate change and infectious diseases, they aim to provide the necessary evidence for effective global health policies and strategies.
