This research is established to identify the COVID-19 Severity Index, according to which we can specify that how much Pandemic is severe. For this purpose, we study the two regions of the world, Asia and Europe, where the COVID-19 Distension was severe than the other regions of the World. We compare the severity of pandemic between Asia and Europe, and we determine the Country Count of COVID-19 severity for both regions. Country Count determines that for which region the pandemic is most severe. For this purpose we used the Pandemic Severity Index (PSI) established by the Centers for Disease Control and Prevention (CDC). We used case fatality ratio (CFR) to determine the severity levels for selected 40 countries from Asia and 40 from Europe. A Country Count is calculated for both regions. According to our study most of the countries of Europe are of Level 5 Severity index, and in Asia Country Count for Level 4 and Level 5 are almost equal.
