Introduction: Coronaviruses (CoV) is a diverse group of viruses that has been described in the literature since 1960, SARS, MERS, and the most recent SARS-CoV-2. This new virus is causing a worldwide pandemic outbreak in the first half of 2020, thousands of deaths, and a significant economic crisis. Objective: Due to this new context, the present study aimed to conduct a systematic study review of the new Coronavirus's global status (COVID-2019) and its aspects compared to the previous SARS-CoV infections MERS-CoV. Methods: The study was conducted from January to September 2020, 89 clinical cases were submitted to further analysis, and 77 studies were selected for systematic review under the PRISMA guidelines. Conclusion: In some countries, the SARS-CoV-2 pandemic appears to be out of control. In case of suspicion, tests are essential to identify the early stages of infection. If necessary, patients need to go into quarantine, and other public health measures should be taken following the World Health Organization guidelines. Advanced support is needed to identify and isolate infected patients, especially vaccines and medicines that help control the virus and the epidemiological situation in each country. These measures are expected to reduce the rate of new cases of SARS-CoV-2.
