Since the early 2020s, the entire world has been in panic and confusion due to the coronavirus that causes CoViD-19. To protect ourselves from the virus, national borders have been closed and people have been ordered to stay home. The world was practically isolated under martial law. The global lockdown caused a total social and economic disruption. After the events that have happened today, we need to be prepared for further changes that will soon affect our lives. This book summarizes the Covid19 pandemic in general, warning us of the dangers it poses beyond the disease. The loss of freedom enjoyed by the western world could be at risk if governments do not moderate authoritarianism and follow the terrible example of countries that do not know or enjoy such freedoms. We save lives but preserve our lifestyle.
