COVID-19 is an emerging and rapidly evolving epidemic. The cumulative number of confirmed cases globally reached 1,040,772 on April 4, 2020, comprising 149,790 (14.39%) cured cases, and 55,698 (5.35%) deaths. The causative organism has been designated as the 2019 novel coronavirus (2019-nCoV). On January 30, 2020, the epidemic was declared a public health emergency of international concern by the World Health Organization (WHO) (Fisher and Heymann, 2020). On February 11, 2020, the WHO Director-General, Tedros Adhanom Ghebreyesus, announced that the disease caused by this new coronavirus was “COVID-19,” which is an acronym for “coronavirus disease 2019.” The virus seems to be highly contagious and had quickly spread to 119 countries and regions by March 12, 2020. The clinical spectrum of COVID-19 varies from asymptomatic or paucisymptomatic forms to clinical symptoms characterized by respiratory failure that necessitates mechanical ventilation and support in an intensive care unit (ICU), to multiorgan and systemic manifestations in terms of sepsis, septic shock, and multiple organ dysfunction syndromes (MODS) (Wu and McGoogan, 2020). Currently, there is no effective anti-coronaviral drug that is recommended for treatment of COVID-19, and no vaccine is available. There is no evidence supporting the efficacy of broad-spectrum antibiotics, gamma globulin, interferon, or corticosteroid therapy for COVID-19. Treatment is symptomatic, and oxygen therapy represents the major intervention for patients with severe infection. Mechanical ventilation may be necessary in cases of respiratory failure refractory to oxygen therapy (Huang et al., 2020; Zhang et al., 2020).
