Increased risks of viruses spread by mammals
Context
A study published by Nature journal has predicted that the rising temperatures and rapid climate change across the globe is likely to drive 15,000 new instances of viruses being transmitted from mammals to mammals by 2070.
About
Key highlights of the study:
- A majority of the 10,000 virus species that have the capacity to infect humans are moving silently in the wild mammals at present.
- As the temperature rises, numerous animal species will forsake their natural habitats and migrate to cooler areas, where they will encounter several new species for the first time. This will lead to viral transmission in animals.
- A surge in viruses leaping between species may result in future outbreaks like the COVID-19 pandemic, posing a major danger to both animal and human health.
- Virus-jumping hotspots will include locations with diverse ecosystems (especially in Africa and Asia) as well as areas extensively populated by people (India and Indonesia).
- The transmission of viruses and diseases from animals to people will occur in highly populated areas across the world.
- This process has most certainly already begun and will keep going even if the world takes swift action to reduce carbon emissions, posing a significant threat to both humans and animals
- Bats, which are thought to have contributed to the beginnings of Covid-19, are believed to be virus reservoirs and will continue to transmit viruses regardless of climatic change.
