Different versions of the lab origin hypothesis present different scenarios in which a bat-borne progenitor of SARS-COV-2 may have spilled over to humans, including a laboratory-acquired infection of a natural or engineered vi
Most large Chinese cities have laboratories that study coronaviruses, [19] and virus outbreaks typically begin in rural areas, but are first noticed in large cities.

[127] Swine acute diarrhea syndrome coronavirus (SADS-CoV), which is related to bat coronavirus HKU2, causes diarrhea in pigs. [134] Porcine epidemic diarrhea virus (PEDV) is a coronavirus that has recently emerged and similarly causes diarrhea ...
Alphacoronavirus amsterdamense [1] ( also called Human coronavirus NL63 abbreviated HCoV-NL63) is a species of coronavirus, specifically a Setracovirus from among the Alphacoronavirus genus. It was identified in late 2004 in patients in the Netherlands by Lia van der Hoek and Krzysztof Pyrc [ 2 ] using a novel virus discovery method VIDISCA. [ 3 ]
