On January 27, 2020, a brother of the leader of this religious group was hospitalized in Daenam Hospital in Cheongdo, a town which is 27 km from Daegu. His brother died on January 31, and they had a funeral ceremony for two nights and three days from January 31 to February 2 in a hospital funeral home located in Daenam Hospital. Because this was the funeral service of the leader's family, many members (about 170) of the religious group visited the hospital funeral home for 3 days. A 61-year-old woman from this religious group who visited the funeral was later confirmed with COVID-9 on February 23. Of note, she lived in Daegu and occasionally commuted to Seoul. Tracing her movements, KCDC found that she attended two worship services at the Shincheonji Church in Daegu with at least 1,000 other members of her religious group.</p><p><xref ref-type="fig" rid="F1">Fig. 1C</xref> shows the timeline of the confirmed case in a patient transporter who worked at the Eunpyeong St. Mary's Hospital with over 800 beds located in northern Seoul.

Among them, seven patients (7/22, 31.8%) were from the psychiatric ward of Daenam Hospital, where they had been hospitalized for several years in poor general conditions. The youngest patient was a 35-year old Mongolian patient. He was already in a serious condition from chronic hepatic failure with cirrhosis and esophageal variceal bleeding. A 40-year old male with hypertension died suddenly, was found the next morning by a coworker, diagnosed with COVID-19 later. Including this patient, the diagnosis was made after death in five patients (5/22, 22.7%). One patient (mortality number 3) died at home suddenly, the rest of the three patients died during hospitalization (mortality numbers 1, 9, and 16), and one patient (mortality number 14) died at home while waiting for the pending test result. Of note, two patients (mortality numbers 13 and 22) were at home isolation with positive results waiting for the hospitalization, but their condition aggravated rapidly and they died. Three patients (mortality numbers 13, 14, and 16) died on arrival at the hospital.<xref rid="B14" ref-type="bibr">14</xref><xref rid="B15" ref-type="bibr">15</xref> Therefore, even though most of COVID-19 patients may have mild clinical courses, individuals with old age and/or underlying medical conditions should be carefully monitored.</p></sec><sec sec-type="conclusions"><title>CONCLUSION</title><p>COVID-19 is a novel threatening viral infection to human society. An exponential increase in numbers of COVID-19 patients in Korea appeared to be mainly caused by exposure among the members of a religious group with the additional community- and hospital-transmission. The transmission exploded mainly in Daegu and neighboring areas. With this sudden and massive increase in confirmed cases, there is an urgent need and preparation for treatment strategies for serious or critical patients. Also, plans and actions for mild cases should properly proceed.</p><p>Furthermore, increasing cases without epidemiologic links in the parts of the nation may herald the risks for additional cluster outbreaks in the coming weeks. Monitoring for such potential clusters of the outbreak are needed, and countermeasures should be urgently prepared.</p><p>Koreans should remain calm and vigilant and continue to be socially responsible. The government, the health authority, experts in the field, and all Koreans should cooperate to overcome this challenging outbreak with a prompt and dynamic response.</p></sec></body><back><ack><title>ACKNOWLEDGMENTS</title><p>We express our sincere consolation for the patients and their families who had COVID-19 in the Republic of Korea.
