In the historical process, there have been pandemic periods that affect the whole world from time to time. According to the definition of WHO (World Health Organization), a pandemic is considered to have started only when the following 3 conditions are met: • The emergence of a disease that the population has not been exposed to before • The causative agent of the disease infecting people and causing a dangerous disease • Spread of the disease factor easily and continuously among people A disease or medical condition cannot only be considered a pandemic because it is widespread and kills large numbers of people, but must also be contagious. For example, although cancer is a disease that causes many deaths in humans, it is not considered a pandemic because it is not contagious. There have been major epidemics in world history. Antoninus (Galen) Plague (165-180 AD), Justinian plague epidemic (AD 541-542) Black Plague (1346 - 1350), Fifth Cholera Pandemic (1879 - 1881), Modern Plague (third plague pandemic) (1894-1903) , Sixth Cholera Pandemic (1899-1923). Approximately 75 million people died in these epidemics. Spanish Flu (1918 1920) More than 20 million people died. (H1N1), Asian flu (1957 1958), HIV / AIDS (1960), Hong Kong flu (1968 1969) and Corona virus pandemic (covid 19, 2019 2020. It is also obvious that these pandemics, which affect the history and development of humanity, will cause bigger problems in the future with the increasing human population and the depletion of world resources. As scientists, this study aims to provide information to the public about the definition, development and spread of the virus that causes the current Covid 19 pandemic and to present it as a book section to share with researchers
