<p>A new study suggests that the next viral pandemic may emerge from the Arctic amid melting glaciers caused by climatic change, increasing risks of next Ebola, influenza, or SARS-CoV-2 arriving sooner than predicted by the experts.&nbsp;</p>

<p>In an attempt to identify viruses present in the environment, researchers analysed solid and lake sediment from Lake Hazen, a freshwater lake in the northern part of Ellesmere Island in Canada (north of the Arctic Circle). The scientists sequenced segments of DNA and RNA found in the soil.&nbsp;</p>

<p>They used a computer algorithm to understand how the viruses are related to animal, plant, and fungi hosts present in the area. After the analysis, the team learned about the viral spillover risk.&nbsp;</p>

<p>The risk is basically the ability for viruses to reach into new host species, and eventually keep spreading. Similar to what the world saw during the initial spread of SARS-CoV-2.&nbsp;</p>

<p>In their paper published in 'Proceedings of the Royal Society B: Biological Sciences', the researchers wrote: "Spillover risk increases with runoff from glacier melt, a proxy for climate change.

<p><strong>What is a pandemic?&nbsp;</strong></p>

<p>A pandemic is a disease that spreads over a whole country or the whole world. It is an epidemic of an infectious disease. The pandemic impacts multiple continents, affecting a substantial number of people. Notably, a widespread endemic disease with a stable number of infected individuals is not a pandemic.&nbsp;</p>
