58% of human infectious diseases can be worsened by climate change – we scoured 77,000 studies to map the pathways

Climate change can exacerbate a full 58% of the infectious diseases that humans come in contact with worldwide, from common waterborne viruses to deadly diseases like plague, our new research shows

Our team of environment and health scientists reviewed decades of scientific papers on all known pathogenic disease pathogens to create a map of the human risks aggravated by climate-related hazards.

The numbers were jarring. Of 375 human diseases, we found that 218 of them, well over half, can be affected by climate change.

Flooding, for example, can spread hepatitis. Rising temperatures can expand the life of mosquitoes carrying malaria. Droughts can bring rodents infected with hantavirus into communities as they search for food.

With climate change influencing more than 1,000 transmission pathways like those and climate hazards increasingly globally, we concluded that expecting societies to successfully adapt to all of them isn’t a realistic option. The world will need to reduce the greenhouse gas emissions that are driving climate change to reduce these risks.

Biological research: Rethink biosafety

Tim Trevan calls on those working with organisms that are hazardous, or could be so, to take lessons from the nuclear industries, hospitals and other sectors that have established a safety culture.

Nature – Two months ago, the US Department of Defense froze operations at nine biodefence laboratories where work is done on dangerous pathogens. Inspectors had discovered live anthrax outside a containment area at the US Army’s Dugway Proving Ground — a facility in Utah that tests defence systems against biological and chemical weapons.
