Ecology: Climate change can aggravate over half of known human pathogens
A paper reporting that 58% of human infections were exacerbated by climate hazardsNature Climate Change will be published inThe findings demonstrate that continued climate change poses additional risks to human health.
It is widely accepted that climate change affects human vulnerability to certain types of diseases.Previous studies have focused primarily on specific pathogen groups (e.g., bacteria and viruses), responses to specific hazards (e.g., heatwaves and increased flooding), and modes of transmission (e.g., foodborne and waterborne). However, no study has revealed the full extent of the threat to humans in terms of climate change and disease.
Camilo Mora and colleagues systematically review the literature to present 286 empirical examples linking human pathogenic diseases (10 in total) with climatic hazards (3213 in total) such as warming, flooding and drought. ) was revealed. 277 diseases were found to be exacerbated by at least one climate hazard, and only 1 to be mild due to climate hazards alone.
Overall trends showed that climate hazards exacerbated 58% of diseases in authoritative lists of infectious diseases reported to have affected humans.Examples of hazards include hazards that have brought humans closer to pathogens (e.g. storms and floods that have caused migrations associated with cases of Lassa fever and Legionnaires' disease) and hazards that have brought pathogens closer to humans (e.g. Lyme disease, There is global warming that has expanded the area where organisms that carry diseases such as dengue fever and malaria are active.
Mora et al. say that their findings reveal unique pathways in which climate hazards drive disease, underscore the limits of societal adaptive capacity, and reduce greenhouse gas emissions. It concludes that it emphasizes the necessity.
