Various articles have been compiled to identify as soon as possible the active cases and thus reduce the number of infections.
Materials and methods: This research was conducted on the basis of scientific articles and books, related to COVID-19.
Methods: This research was conducted based on 15 scientific articles and 3 books, related to COVID-19.
Results: The most important risk factors are diabetes mellitus, hypertension, obesity, age and sex. The most common symptoms in Latin America are dry cough, fatigue, sore throat, and fever. The preferred diagnostic test for COVID-19 is the polymerase chain reaction for its specificity and sensitivity
Conclusions: As a conclusion, the main objective of the research was achieved, which is to inform the reader about the most relevant symptoms of SARS-CoV-2 in order to improve the identification of suspected cases.
