The disease has spread worldwide since, March 1, 2020, and then became a pandemic. All countries of the world have been affected. To date, there are 215,882,875 confirmed cases with 4,492,818 deaths. USA is the country with the greatest number of confirmed cases and most deaths, followed by our neighboring country Brazil. COVID-19 pandemic has been the impetus for the immediate use of antiviral drugs, such as chloroquine and Remdesivir, amongst others. The former was disapproved by FDA. However, the COVID-19 vaccine has been the only real solution to date, providing over 90% efficacy in all cases. Over 150 pharmaceutical companies are still pursuing research in order to find the best vaccine.
