The entire world is facing complex challenges linked to the rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease COVID-19. Epidemiologists and virologists are in the first line in understanding where the virus originated, how it adapted to a new host (humans) and how it spreads. Even if to date there is still uncertainty about the exact source, currently available evidence identifies horseshoe bats (Rhinolophus affinis) and pangolins as intermediate host that might have facilitated transfer to humans in Wuhan region, followed by a rapid spread across China, Europe and the rest of the world.
