Projection of Covid-19 Cases: Which Model to Use?
Researchers around the world have been flabbergasted by the extent and pace of Covid-19 spread. Even strong healthcare systems of the western world have been proven to be not 'strong enough' to fight Covid-19, let alone what that means for the healthcare system of developing countries like Bangladesh which has been in complete disarray from the beginning. Scientists of all fields are trying to learn and possibly contribute to bring some new insights and to contribute with their capacity—probably unseen in the recent past. While this combined effort is noteworthy, but we can and need to do more. Projection modelers are playing a pivotal role in helping the policymakers by providing information as to what is to expect so that the health system can be better prepared. A plethora of models for projections are available that are giving large variations in projected numbers of cases and deaths--this is one of the core features of the modeling, and so not necessarily bad.
