The transmission of a novel infectious pathogen among humans such as the SARS-CoV-2 may be complicated, but it is far from rare. As many as 75% of emerging human infections have some connection to a zoonotic disease [11]. Typically, viral, bacterial, fungal, or parasitical pathogens may emerge due to one or a combination of factors: human and animal interaction, changes in human or animal behavior, consumption of exotic animal foods, globalization, world travel, or things that disrupt human and animal interactions, such as wars, natural disasters, and environmental changes. The pathogen itself may play a role in its pattern of emergence by mutation; in some instances, humans may facilitate the rapid progress of these mutations by the use of antimicrobials. Thus, while often multifactorial and complex, the sudden emergence of a novel infectious agent is not a novelty [12]. The novel SARS-CoV-2 virus, which first appeared in 2019, is just one of several coronaviruses that have caused epidemics in the past two decades. These pathogens are sometimes able to adapt to new hosts, as occurred with the zoonotic SARS-CoV-2 virus, which appears to have originated in bats, then rapidly accommodated to human hosts [13].
