Most jurisdictions will create a special investigation team to take over outbreaks as they require expertise and resources beyond typical case investigation and contact tracing efforts.
CDC has developed specific guidance for investigating clients with COVID-19 in a number of settings. When relevant, the CDC guidance is highlighted below.
A COVID-19 outbreak indicates potentially extensive transmission within a setting or organization. An outbreak investigation involves several overlapping epidemiologic, case, and contact investigations, with a surge in the need for public health resources.
More emphasis on active case finding is recommended, which can result in more contacts than usual needing testing and monitoring.
