Graph database for outbreak tracking and management

An outbreak management server apparatus comprising:

• an interface to receive patient data related to patients;
• a node processor communicatively coupled to the interface and configured to create an outbreak tracking graph database by:
• comparing the patient data to disease parameters of different diseases, the disease parameters specifying conditions for a ‘possible’ classification for the respective disease, a ‘probable’ classification for the respective disease, and a ‘confirmed’ classification for the respective disease, and
• for each patient in which at least one of the ‘possible’, ‘probable’, and ‘confirmed’ classification is determined for one of the diseases, add the patient to the graph database that is associated with an outbreak of the determined disease by
• creating a host node for the patient,
• creating an episode node that is connected to the host node via a ‘case’ link, the episode node being associated with episode parameters that are related to the disease classification of the host, and
• creating an outbreak node that is connected to the episode node via a ‘part of’ link to indicate that the host has become part of the outbreak for the determined disease, the outbreak node being connected to a definition node via a ‘defined as’ link, the definition node specifying the disease parameters of the disease that is related to the outbreak node;
• and
• a database analyzer configured to analyze the graph database that is associated with the outbreak of the determined disease to display for identification at least one of an index patient or relationships among the patients.
