Abstract

In late December 2019, an outbreak of a mysterious viral pneumonia broke out in Wuhan, Hubei Province, People's Republic of China, in which the causative agent was identified as a new coronavirus provisionally named 2019-nCoV. The world is currently experiencing a severe pandemic caused by the infection officially called COVID-19, which occurs due to contamination by the SARS-CoV-2 virus. Despite the countless information about its symptoms, there is still a lack of scientific evidence. Therefore, this work is important to inform the general parameter of the symptomatology of the infection caused by the SARS-CoV-2 virus. The study in question refers to a review of the scientific literature based on the databases Scielo, Lilacs, Pubmed and Bireme; we searched for the descriptors COVID-19, viral infection, SARS-CoV-2. To carry out this study, a survey was carried out from June 2017 to March 2021, with the inclusion criteria of articles in Portuguese, English and Spanish, which met the requirements of the subject in question, in a clear and cohesive manner, published in reliable journals of recognized scientific rigor. Therefore, the general panorama of the symptoms of the infection caused by the SARS-CoV-2 virus was identified, in which milder symptoms were identified, the most frequent being fever, cough, dyspnea, myalgia and fatigue and severe illness usually presenting signs and symptoms of viral pneumonia that may progress to situations of Acute Respiratory Distress Syndrome (ARDS), acute heart failure, acute kidney injury, on infection, sepsis or shock.
