Özet
A coronavirus brought the first pandemic attack of this century as a flu virus did a hundred years ago. This greatest pandemic of the century brings us new opportunities to understand and explore dynamics of a contagious disease. Nearly two year later we are still collecting the evidence to understand the disease. Some basic epidemiological properties are still urgently needed. Not only origin of the virus but also Ro value, possible transmission routes, epidemiologic curves, case fatality rates, seasonality, severity and mortality risk factor, effects on the risk groups, differences between countries and so on still require strong evidence prior to making final suggestions. In this review, we tried to evaluate epidemiological evidence to scrutinize where exactly we are in this pandemic.
