1 Introduction
In December 2019, a novel coronavirus named SARS-COV-2 emerged and became a global pandemic over the span of one month. Actions were taken by governments to restrict international travel and encourage the social isolation of citizens, but all precautions proved insufficient to prevent the pandemic. The cumulative global fatality count due to COVID-19 infection exceeds 3.1 million people as of May 2021 (Johns Hopkins Coronavirus Resource Center 2021).
