All we need to be careful not to panic. We know what it is. The first case of severe pneumonia was reported in China on December 31, 2019 of COVID-19 infection and by January 7 the virus had already been identified.
The genome was available on day 10. We already know that it is a new coronavirus from the same family as the SARS, which we have called SARSCoV2. Lots of deadly viral infectious disease came and vanished off. The same will be going to happen with Coronavirus. Studies has been suggesting that that Coronavirus mutating to its non virulent form. Later or sooner the world will be free from this virus. If you want the recent examples I will take the name of Ebola and Zika which were also declared to a pandemic.
