Understanding how and where the SARS-COV-2 virus, the virus that causes covid-19, started is incredibly important in being better prepared for future epidemics and pandemics.

Investigation into the origin of the outback is ongoing and explores:
* Zoonotic spillover - when a virus enters the human population from exposure to animals.
* A breach (error) in biosafety or biosecurity in Labs working with similar viruses.

At the present time no firm conclusion has been reached.
