The disease has spread from bats to humans through mediated animals (pengloine), but a number of patients have been found to be unrelated to the Wuhan fish market. Therefore, whether or not China's Wuhan fish market is the main area is still controversial, but is believed to be spread through common sources. The WHO Joint Mission for China was held between February 14^th and February 24^th, and comprised of the WHO, scholars, and administrators from various countries. Virus characteristics, epidemiology, health impact, and China’s response to the epidemic were discussed. High-level administrative authorities were persuaded to respond quickly, especially in Republic of Korea and Japan, where large numbers of patients have emerged due to the outflow of patients from China.

Despite advice from the WHO, COVID-19 continued to spread, and the WHO declared it a pandemic on March 11^th. The WHO revised its strategy for the other region from the initial response, and advised the implementation of measures against the pandemic based on the Asian experience. Despite this strategy, the number of COVID-19 patients continue to increase 6 months after the declaration of the pandemic. In particular, the number of cases is increasing in the United States, India, and Brazil as the disease spreads, and in Germany, Singapore, and Hong Kong, 3 countries that were considered to be exemplary countries, have been experiencing a small wave of outbreaks.

Among 37 therapeutic drugs being trialed for the treatment of COVID-19, only 15 drugs are in Phase 3 clinical trials [2]. There are 26 COVID-19 vaccine clinical trials, and 139 substances are in pre-clinical stages of development [3]. However, currently there’s no silver bullet and there may never be one, so for now, stopping COVID-19 outbreaks comes down to the basics of public health and disease control [4]. Yes, there are still important measures such as tracing close contacts of patients, early testing for symptomatic contacts, patient care, isolation, and non-pharmaceutical intervention but, first of all, we must remember not to go back to the previous norms of society. Active adaptation to the new normal is critical. Firstly, at the individual level, the patient should isolated, and personal behavior require that masking, hand washing, and coughing etiquette are followed. When an individual uses transportation facilities, wearing a mask is still important. Secondly, in the workplace, employees with fever should not be allowed to go to work, and should be encouraged to work from home. Flexible working, remote working, and a new workplace culture is needed. Thirdly, on a community level, religious facilities, facilities for large gatherings (marts, stadiums, theaters), and schools, need to encourage handwashing, social distancing, and mask wearing, and provide ventilation indoors to reduce the risk of transmission of infection.

In many countries, essential services have been damaged due to paralysis of transportation facilities, closure of medical institutions, and a reduction in the number of individuals using these facilities due to COVID-19 lockdown. It has also damaged mental health, rehabilitation, disease screening, prenatal care, and immunization projects. In Korea, acute medical care, such as vaccination and tuberculosis management, has not been significantly damaged, but in the long term, there may be excess deaths due to insufficient management of chronic diseases during the pandemic. As a countermeasure against vulnerable groups such as the elderly, who have reduced access to medical institutions, it is necessary to manage these individuals without face-to-face consultations.
