  • Introduction: Coronavirus disease 2019(COVID-19) is a rapidly spreading epidemic that, like the outbreak caused by two other pathogenic respiratory coronaviruses (sars –cov and mers-cov), often causes severe infection, mainly through respiratory droplets. It is reported that it was first discovered in Wuhan, China, in people who were exposed to seafood, with a mortality rate of 2.27%. According to the World Health Organization and epidemiological studies, more than thirteen million people worldwide have been infected and more than one million have died so far (Sars, Mers, Covid-19) in global pandemics.
  • Methods: This study was conducted in 2020 by searching for keywords such as corona virus family and global pandemics in reputable databases such as: pub med and google scholar. Finally, 15 articles were found, of which 10 articles were used
  • Results: Based on studies from articles, the results show that this disease was first discovered in Wuhan, China in people who were exposed to seafood. Symptoms of this disease include fever, dry cough and fatigue, and so far more than thirteen million. People in the world are infected with this disease and more than one million people die and in terms of genome sequence from 75 to 80% is the same as SARS-CoV. Its treatment agents include plasma therapy, which is the best way to improve the recovery rate of patients. To control the prevalence of COVID-19 early detection and reduced close contact is the best way to prevent the disease. Reducing Secondary Infections Among Medical Staff Knowing the genome sequence facilitates rapid detection of the virus Rapid response The Chinese Clinical and Scientific Public Health Associations facilitate the recognition of clinical diseases and a basic understanding of the epidemiology of infection.
  • Conclusion: According to the findings, it is better to set up a risk reduction program that is not a risk factor for us and it is recommended that we continue to do the treatment process and proper protection to do a good job of testing COVID-19.
