COVID-19 - Significant clusters

Last updated: 1:00 pm, 31 May 2020

A significant COVID-19 cluster is when there are ten or more cases connected through transmission and who are not all part of the same household. The cluster includes both confirmed and probable cases.

Public health staff quickly follow up confirmed cases as soon as they are identified. Following up confirmed cases quickly and isolating close contacts works to contain clusters and prevent the disease spreading any further. All clusters are being investigated and managed by public health officials.
