COVID-۱۹: Apocalypse Now?

The COVID-۱۹ pandemic due to the novel Severe Acute Respiratory Syndrome coronavirus ۲ (SARS-CoV-۲) has tremendously affected the world; including the richest and the poorest ones, from East to West (۱). The centennial pattern of the world pandemics was much similar to this one as quoted by many authors.But after many decades, is there any difference in the COVID-۱۹ pandemic with the ۱۹۱۸ Spanish flu pandemic? Spanish flu has been called as the mother of all pandemics (۲, ۳). Is the current COVID-۱۹ more aggressive than Spanish flu? Many believe the current COVID-۱۹ is not much less than its precedent one. Just think a moment! After ۱۰۰ years, are we the same community as we were? The answer is both yes and no!
