Cluster: It refers to an aggregation of cases of a disease. A coronavirus cluster occurs when there is a concentration of infections in the same area at the same time.
In general, the World Health Organization (WHO) uses the following categories (PDF) to describe transmission patterns: sporadic cases, clusters of cases and community transmission.
Sporadic cases refers to a small number of cases (one or more) that are either imported or detected locally; clusters of cases refers to cases that are clustered in time, geographic location and or by common exposures; community transmission refers to larger outbreaks of local transmission that can be defined through different approaches, including big numbers of cases not linkable to transmission chains and multiple unrelated clusters in several areas.
