COVID-19: More on its Possible Origin

The struggle between humans and infectious diseases dates back to the beginning of civilization, where the increase in infectious entities is closely associated with human misconduct and ecosystem management. The objective of this research was to provide more up-to-date information on the possible origin of the new coronavirus officially known as SARS-CoV-2, which causes COVID-19. A series of data/information on the possible origin of the new pandemic is presented, broken down as follows: Where does this virus come from?; bats and pangolins as potential vectors; probable theories about how this virus spread to humans; what do we know?; what we don't know?; and how this virus spread so rapidly until it became a pandemic. It is concluded that this is a highly infectious entity with a high probability of zoonotic transmission, with bats and the mammal known as the pangolin standing out as potential reservoirs, where the joint efforts of all human beings who inhabit, this planet must unite to win the battle against this new coronavirus.
