Key Findings
· The terms cluster and outbreak both describe the occurrence of new disease cases within a particular location and time period. The number of cases within a cluster are not necessarily greater than what is expected, however in an outbreak the number of cases does exceed the usual norm. · In an outbreak the cases are confirmed to be epidemiologically linked while in a cluster an epidemiological connection is only suspected. · Not all clusters are outbreaks, however each cluster needs to be investigated
· Understanding how to characterize COVID-19 cases based on a suspected or proven epidemiological link can better guide prevention of disease spreading
