Since the first patients of Coronavirus Disease-19 (COVID-19) outbreaks through Zumba dance classes were confirmed on
February 24, 2020, the number of confirmed cases rapidly increased in South Korea. As of March 11, 2020, 116 cases of
COVID-19 related to Zumba dance classes were confirmed. This report aims to investigate the epidemiological characteristics of outbreaks through Zumba dance classes in South Korea. To accomplish this purpose, we analyzed 116 confirmed cases of COVID-19 obtained from epidemiological monitoring. There were 29 (25.0%) male cases and 87 (75.0%) female cases. The average age was 39.1 (Median 42.0). 95 cases (81.9%) lived in Cheonan-si where Zumba workshop was held. Of the 116 cases, 65 cases (56.0%) were transmitted in Zumba dance class. 37 cases (31.9%) were infected through family. 21 cases (20.8%) reported initial symptoms of fever or heat sensation, 18 cases (17.8%) reported having a sore throat, 21 cases (20.8%) reported having a cough. 12 cases (11.9%) reported having a sputum, 5 cases (5.0%) reported having the chills, and 14 cases (13.9%) reported having muscle pain. There were 25 asymptomatic cases (24.8%). This case is the first report of COVID-19 outbreak through dance classes, and is expected to contribute to establish a response strategy for COVID-19 outbreak through vigorous exercise in close space.
