In South Korea, close to 56% of the infections emerged from a church frequented by an infected woman. In Singapore, a dinner party was found responsible for 10% of the cases.

Earlier this week, India found one such massive cluster in a religious congregation held in mid-March in Nizamuddin, Delhi.
