One of the emergent global challenges in managing infectious diseases is dealing with the novel coronavirus 2019 (COVID-19). With the extremely high infection rate and relatively high mortality, individuals naturally began worrying about the COVID-19. Apart from reducing the transmission rate, considering an individual's knowledge and fear is a vital aspect for their psychological wellbeing and may also largely influence the manner in which an individual may adhere to preventive measures and thereby determine the clinical outcome of COVID-19.
