指示病例（英语：index case），又称为原发病例（英语：primary case），在流行病学调查中是指在一定人群中的最初的病例。[1][2]指示病例可能表示疾病的来源、可能的传播以及多次爆发之间的传染源。指示病例是表明一次爆发的首个病例。如果发现多个最初的病例的话，会依次以原发（primary）、二代（secondary）、三代（tertiary）等进行命名。[3]


"Patient Zero" 特別指基坦·杜加，他是艾滋病在北美传播的指示病例。[4]

Run scheduled task as local user group (not BUILTIN)

Image
0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users).
