  • Over the two last decades, coronaviruses have affected human life in different ways, especially
    in terms of health and economy. Due to the profound effects of novel coronaviruses,
    growing tides of research are emerging in various research fields. This paper employs a
    co-word analysis approach to map the intellectual structure of the coronavirus literature for
    a better understanding of how coronavirus research and the disease itself have developed
    during the target timeframe. A strategic diagram has been drawn to depict the coronavirus
    domain"s structure and development. A detailed picture of coronavirus literature has been
    extracted from a huge number of papers to provide a quick overview of the coronavirus
    literature. The main themes of past coronavirus-related publications are (a) 'Antibody-
    Virus Interactions,” (b) 'Emerging Infectious Diseases,” (c) 'Protein Structure-based Drug
    Design and Antiviral Drug Discovery,” (d) 'Coronavirus Detection Methods,” (e) 'Viral
    Pathogenesis and Immunity,” and (f) 'Animal Coronaviruses.” The emerging infectious
    diseases are mostly related to fatal diseases (such as Middle East respiratory syndrome,
    severe acute respiratory syndrome, and COVID-19) and animal coronaviruses (including
    porcine, turkey, feline, canine, equine, and bovine coronaviruses and infectious bronchitis
    virus), which are capable of placing animal-dependent industries such as the swine and
    poultry industries under strong economic pressure. Although considerable research into
    coronavirus has been done, this unique field has not yet matured sufficiently. Therefore,
    'Antibody-virus Interactions,” 'Emerging Infectious Diseases,” and 'Coronavirus Detection
    Methods” hold interesting, promising research gaps to be both explored and filled in
    the future.
