While the virus was certainly not engineered in a laboratory, this doesn't mean we haven't played a role in the current pandemic. Human impingement on natural habitats, biodiversity loss and ecosystem degradation are making virus spillover events much more likely, a major new study from scientists in Australia and the US has found.

Here are the factors that help Coronavirus to emerge:

Deforestation, habitat encroachment

As people move further into the territories of wild animals to clear forests, raise livestock, hunt and extract resources, we are increasingly exposed to the pathogens that normally never leave these places and the bodies they inhabit.

So-called "wet markets" selling produce, meat and live animals provide another incubator for the emergence of infectious disease. Scientists believe there's a strong possibility SARS-CoV-2 emerged at a wet market in Wuhan, China.

But in January 1996, Ebola, a deadly virus then barely known to humans, unexpectedly spilled out of the forest in a wave of small epidemics. The disease killed 21 of 37 villagers who were reported to have been infected, including a number who had carried, skinned, chopped or eaten a chimpanzee from the nearby forest.
