COVID-19 Disease Clusters in Hawaii

A disease cluster refers to multiple cases of a disease occurring at one time, in one geographic location, or among people with the same or similar shared exposures. Public health officials investigate and study disease clusters because they can provide important information about how diseases are transmitted between individuals and among groups of people; this information can then be used to identify risk factors, inform official recommendations, design interventions, and implement policies to prevent, mitigate, and stop the spread of that disease in communities. This report summarizes COVID-19 clusters that have been identified through statewide case investigation and contact tracing efforts and are actively under investigation within the State of Hawai‘i during the specified reporting week.

Cluster reports are uploaded every Thursday by 1pm. If there is a holiday on a Thursday, the cluster report will be uploaded the following business day.
