On December 31, 2019, the World Health Organization (WHO) was informed about a cluster of unknown causes of pneumonia detected in Wuhan City, Hubei Province, China. On January 12, 2020, a new coronavirus was detected in samples from cases, and the first analysis of virus genetic sequences suggested that this was the cause of the epidemic. This virus was called SARS-CoV-2 and associated disease COVID-19. As of April 26, 2020, more than 2.9 million cases were identified, with more than 203 000 deaths from 210 countries worldwide. As a result of the intensive studies of the Ministry of Health in our country, it is trying to control the spread of COVID-19 through the isolation of cases and quarantine of close contacts, through epidemiological research. However, insufficient epidemiological data to determine the degree of possible spread make studies more difficult (complicate the studies) . Although possible points of contamination have been identified retrospectively by epidemiological research, they have played an important role in demonstrating their use in supporting epidemiological research. COVID-19 continues to spread, while pharmacological compounds are being developed in the treatment of the disease, and while prevention and mitigation measures are intensifying. In this article (research), a brief review of current data about COVID-19 in terms of person-place and time characteristics is presented within the framework of descriptive studies.
