In many COVID-19-affected nations, the case count started rising exponentially after health workers discovered a group of people who got infected at one place and mostly at the same time. Such groups are termed “clusters”.

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.
