COVID-19: Features, Clinical Course and Concerns

The coronavirus disease 2019 (COVID-19) was first detected in December 2019 in Wuhan, China. So far, 136 reports from the WHO were reported. In the latest report, 6416828 patients in almost all countries have been infected with COVID-19. The present study discusses the different aspects of COVID such as emergence, signs and symptoms, comparisons with SARS and MERS, concerns, governments' actions in controlling the virus, and a descriptive analysis of the spread and death. The emergence of the coronavirus family in the last two decades has created a public health issue around the world. It has also caused serious damages to the infrastructure, economy, culture, and communities of countries. Thus, affected governments have taken steps to reduce these concerns such as quarantine, education, traffic control, closure of recreational centers, reduction of working hours, etc. Despite strict measures to contain the COVID-19, this virus is still expanding and the question of "what actions should be taken with what political package?" is being asked. To answer this question, it is important to understand the process of disease occurrence, and modeling different interventions on changing the natural course of the disease are very important.
