How did the coronavirus (COVID-19) start?
The COVID-19 was first detected on December 2019, in Wuhan City (China). It initially existed in animals, before transmission to humans.
COVID-19 is a zoonotic virus, so can transfer from animals to humans and vice versa. Experts believe this strain of the virus originated in bats, then likely hung out in another species—where it lived and reproduced—before spreading to humans (likely at the Wuhan wet market).
