Coronavirus disease 2019 (COVID-19) first broke out in December 2019 in Wuhan, China, and has spread rapidly worldwide since the beginning of 2020. This new infectious disease is associated with a variety of symptoms and, in severe cases, leads to organ failure and death. On March 11, 2020, the World Health Organization (WHO) (2020a) declared the COVID-19 outbreak a global pandemic. Since then, the primary goal has been to slow down the spread of the novel coronavirus (SARS-CoV-2), which is responsible for the disease and is easily transmitted by direct and contact transmission.
