AB  - It seems that coronaviruses take an important place in the 21th century history. Five of seven human coronavirus was isolatedin this century. Unfortunately, last three of them entered our life with a fear of outbreak, pandemic or death. Last human coronaviruswhich emerged world from Wuhan China, SARS CoV-2 and its clinical expression, Coronavirus disease (COVID-19) recently takena significant place in our daily practice. Initial reports showed that, its origin was bats. It transmitted human to human by droplet andcontact routes, but some doubt about airborne, fecal or intrauterine transmission also should be removed. Its R0 value is 2.3 but it couldbe as high as 5.7. Its case fatality rate was 6.3, but it was different in different ages and counties, and it could be over 15%. Accordingto early models total 10–12 weeks is required to control an outbreak in the community. While different countries show different dailycase numbers, total number of case, case mortality rates or R0, it seems they show a similar epidemic curve. Every day we learn newdata about the current outbreak. Since the outbreak is not over yet, every detail should be evaluated carefully and the updates should befollowed closely to monitor the epidemiological properties of COVID-19.
