指示病例




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). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
