Chair

One of the Outbreak Control Team (OCT) members should be made the chair of proceedings; their main responsibility is to manage the outbreak response (coordinate people, facilitate investigations, make effective communications and ensure timely delivery of agreed objectives) rather than be involved in the investigation itself.

Updates

Regular updates of factors such as case ascertainment, patient outcomes and environmental results must be conveyed to all core members of the outbreak control team.

Data logging and record keeping

The OCT should arrange for careful recording of decisions and processes undertaken during the investigation, and in some situations a member should be designated as chief logger with responsibility for note/record keeping. The outbreak control team should take into account all applicable legal issues with data protection and data sharing and review these regularly in preparation for future outbreak investigations.
