| Sumario: | The new coronavirus first appeared in December 2019 in Wuhan, China, being officially named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by the International Committee on Taxonomy of Viruses (ICTV), as well as the name of the disease has been described as COVID-19 (coronavirus disease 2019). In March 2020, the disease was considered a global pandemic, with currently more than 514 million cases worldwide, with 6.4 million deaths. Severe cases of COVID-19 progress to acute respiratory distress syndrome (ARDS), on average about 8–9 days after the onset of symptoms. It is also worth mentioning that the severity of the disease in patients is not only due to the viral infection but also due to the host response. This phase, called a cytokine storm, reflects a state of systemic immune activation, with high levels of cytokines, such as IL-6, IL-1b, IL-2, IL-12, IL-18, TNF, and interferon gamma (IFN-γ). In this sense, the management of the disease largely depends on symptomatic and supportive treatments. For severely or critically ill patients with acute respiratory distress syndrome (ARDS) and sepsis, in addition to supplemental oxygen, mechanical ventilation, and ARDS-specific therapies, antiviral and antibiotic treatments should also be considered. Thus, the purpose of this chapter is to describe the pathophysiology and treatment of SARS-CoV-2 infection. |
