As per World Health Organization, all the evidences so far show that SARS-CoV-2 has a natural animal origin and is not a constructed virus and most probably has its ecological reservoir in bats. Furthermore, SARS-CoV-2, belongs to a group of genetically related viruses, which also include SARS-CoV and a number of other CoVs isolated from bats populations. MERS-CoV also belongs to this group, but is less closely related.
