A new coronavirus cluster in South Korea was linked to a religious group in the northwestern province of Gyeonggi on March 16, 2020. The 46 members of the Grace River Church tested positive for the virus that causes Covid-19 after a sprayer was used to inject salt water in their mouths in the false belief that it would fight the illness. On the same day, South Korea reported another 25 cases from two other churches in the same province which surrounds the capital Seoul.
