Most coronaviruses cause only mild upper respiratory infections, but sometimes they cause fatal respiratory disease and outbreaks, as experienced in cases of SARS-CoV or MERS-CoV. This disaster has been warned until recently that new mutants of coronavirus can occur anytime. 5, 6 The emergence of these mutants is caused by species jumping between human and other animals. Therefore, it is likely to occur in an environment where human and animals are in close contact. The current outbreak is also suspected of being caused by mutants from species spillover in Wuhan's wild animal market. The 2019-nCoV is rapidly spreading throughout China and around the world in a relatively short period of time. As of 29 January 2020, a total of 6,140 cases were confirmed in 19 countries, including Korea, of which 132 died (in China only) and had a mortality of 2.1%. 7 As much as the 2015 MERS-CoV outbreak, we are also learning a lot of lesson from this disaster. Because epidemic is a national disaster, not only medical institutions but also governments have to be active. Hence, honesty and transparency are, above all, the virtues that governments should have. Our country is excellent at coping with this disaster, thanks to the experiences that we have gained during the 2015 MERS-CoV outbreak. 8 Our defense system is at least more solid and faster than it used to be. What do you expect this nCoV outbreak to be in the future? Based on the SARS epidemic precedence, the outbreak is expected to last at least three months. And this outbreak is expected to have a greater amount of transmission than the 2015 MERS-CoV. Recently, the possibility of transmission by asymptomatic infected people has also been raised carefully although its evidence is unclear. Therefore, we should also prepare for the spread to communities by asymptomatic infections. 9,10 After the MERS-CoV outbreak in 2015, there was a self-tormenting expression in the medical profession society: 'Patients die, hospitals die, and civil servants are praised.' But the bad memories of the past should never be repeated. In fact, at present, cooperation between community health centers and private hospitals is not always harmonious. The government needs to be more active, not just to leave everything to the medical staffs. After all, the responsibility for the controlling nationwide epidemics lies with health authorities of the government. The Korea Center for Disease Control and Prevention (KCDC) must be the control tower of the present disaster in Korea and all other central or local governmental organizations must cooperate with the KCDC. Toward the end of the 2019-nCoV outbreak we must go on a march of arduousness. Health workers, the government, and the people will need to unite to overcome this disaster.
