Coronavirus disease 2019 (COVID-19), caused by a virus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was announced as a global pandemic by WHO on 11 March, 2020. Although COVID-19 is not life-threatening in most people, it can be lethal for others. The exact mortality rate varies greatly between regions and countries, particularly with an increased risk of death in people aged 70 years and older.  Because of its high transmissibility, COVID-19 has challenged health-care systems worldwide, leading to pressure on intensive care beds in Italy with 9–11% of the people infected with COVID-19 requiring intensive care admission.  As a result, countries took various actions to flatten the curve to allow health-care systems to cope with the demand.
