Coronaviruses are not new to the human population. These enveloped ribonucleic acid (RNA) viruses have been the cause for various respiratory and gastrointestinal infections. They have caused serious epidemics of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) earlier. Now, we are battling the current pandemic coronavirus disease-2019 (COVID-19). Though this novel virus has relatively low fatality, it has engulfed the word due to its high infectivity. This review is an attempt to take you through the story of coronaviruses so far, highlighting their virology, evolution, and spectrum of diseases. We have reviewed the effects of COVID-19 on pregnancy, newborns and children, testing and preventive strategies, herd immunity, and the way forward in this ongoing battle.
