Together with the severe acute respiratory syndrome (SARS) coronavirus which threatened as pandemic in 2002–2003 and the MERS (Middle East respiratory syndrome) which was notified in 2012, the current and novel pathogen–novel coronavirus 2019 is the third highly pathogenic human coronavirus that has emerged in the last two decades and is exhibiting rapid survival tactics including transmissibility. Subsequent to its emergence, there has been an outpouring of information and data in the medical and nonmedical literature. The information is also so dynamic that the validity of information, especially the morbidity and mortality data become outdated everyday. This review aims at providing the overview about the agent and the epidemiological similarities and differences between the current novel coronavirus and the previous member of the family, the SARS-CoV and shared thoughts about what to be done further!
