Abstract:

Background: In the past two decades, the human coronavirus (HCoV) outbreaks have gripped the international communities almost six times in different forms [HCoV-OC43 (2001); HCoV-NL63 (2004); SARS-CoV (2003); HCoV HKU1 (2005); MERS- CoV (2012); SARS-CoV- -2 (2019)]. These emerging pathogens have been proven very challenging from medical perspectives, economic conditions, and psychological impact on human society.

Introduction: SARS-CoV-2, a novel coronavirus, has evidenced a historic yet troublesome pandemic across the globe. In humans, its clinical manifestations may range from asymptomatic, severe pneumonia to mortality. Bats are the natural reservoirs of a variety of viruses belonging to the family Coronaviridae. Most of the bats harboring coronaviruses mainly reside in Asian and African regions.

Objective: The objective was to describe the various characteristic features of all coronaviruses, clinical manifestations, and complications associated with SARS-CoV-2. The major goal was to highlight the involvement of the strong immune system of bats in the cross-species transmission of coronaviruses in intermediate hosts and, finally, zoonotic transmission in humans.

Methodology: A systematic literature search was conducted for high quality research and review articles. We searched the databases for articles published between the year 1972 to 2020 with search terms zoonosis, coronaviruses, zoonotic transmissions, clinical manifestations, and the immune system of bats.

Conclusion: The domestic and non-domestic animals come in closer contact with humans. Some requisite measures should be taken to decrease the contact with livestock to prevent further threatening viral transmissions. Furthermore, the remarkable immune system of bats is required to inquire thoroughly to develop novel therapeutics to conquer the evolving coronaviruses in the future.

Keywords: COVID-19, zoonosis, bats, coronoviridae, SARS, MERS, coronavirus, chinese horse-shoe bat.
