Biodiversité

Future pandemics will emerge more often, spread more rapidly, do more damage to the world economy and kill more people than COVID-19 unless there is a transformative change in the global approach to dealing with infectious diseases, warns a major new report on biodiversity and pandemics by 22 leading experts from around the world.

Highlights: Intergovernmental Council on Pandemic Prevention; Addressing risk drivers including deforestation & wildlife trade; Tax high pandemic-risk activities

540,000 - 850,000 unknown viruses in nature could still infect people; More frequent, deadly and costly pandemics forecast; Current economic impacts are 100 times the estimated cost of prevention

Zoonotic viruses infect people directly most often when they handle live primates, bats, and other wildlife (or their meat) or indirectly from farm animals such as chickens and pigs. The risks are higher than ever (2, 3) as increasingly intimate associations between humans and wildlife disease reservoirs accelerate the potential for viruses to spread globally. Here, we assess the cost of monitoring and preventing disease spillover driven by the unprecedented loss and fragmentation of tropical forests and by the burgeoning wildlife trade.
