COVID-19 and its possible origin

The struggle between man and infectious diseases dates back to the very beginning of civilization, where the increase of infectious entities is closely associated with poor human actions and management of ecosystems. The objective of the present research was to outline the possible origin of the new coronavirus officialized as SARS-CoV-2 causing COVID-19. A series of aspects about the possible origin of the new pandemic are presented, broken down as follows: Where does this virus come from? probable theories about how this virus spread to humans, what do we know?, what don't we know?, and what can we do now?. It is concluded that this is a highly infectious entity with a high probability of zoonotic transmission, where bats and the mammal known as pangolin stand out as potential reservoirs, but the possibility of synthesizing this virus at laboratory level should not be ruled out, so we do not know if the virus will become endemic, recurrent year after year or finally be controlled; What we do know for sure is that the joint efforts of all human beings living on this planet are needed to win the battle against this new coronavirus.
