Impacts of Climate Change on Pathogens and One Health

Background

This chapter discusses important changes of environmental factors attributed to climate change. Special attention is given to climate change impact on the One Health concept and its relation to human pathogen occurrence especially in developing countries and the overall implications on human health as a result. Furthermore, the chapter discusses impacts on food borne pathogens, how conditions favourable for pathogen survival in food may alter access and availability to safe food and food resources. 

Methods

Climate change-related scientific data often relies on prediction models in order to gain a better understanding of potential future impacts. However, prediction models are always an extrapolation of currently available data sets. This letter approaches the topic with available scientific evidence from previously published scientific data and data from the current studies of the authors, directly supporting the claim that changes in climate directly affect human pathogens. 

Results and Conclusions

Climate change is playing a profound role in the spread of infectious diseases in developing countries, with significant implications for public health. In order to address the health impacts of climate change in developing countries, it is crucial for governments and organisations to prioritise adaptation and resilience measures.
