For example, imagine that Patient A has a status of “NEGATIVE” for visits on 5/1, 5/2, 5/3, and 5/4, and then a standing of “POSITIVE” for visits on 5/5 and 5/6. If you choose 5/4 as the end of the go to window for Patient A, then Patient A shall be labeled as “NEGATIVE” in the plot. If you choose 5/5 or 5/6 as the end of the go to window for Patient A, then Patient A will be labeled as “POSITIVE” within the plot. Behind the scenes, VisitContactTrace first identifies the primary visit-based contacts of the index individual you chose in the course of the window of time you specified. Then, it identifies the visit-based contacts two to a few orders of separation away from your index particular person. The visits for these contacts must have occurred after the first contact visit dates (and tertiary contacts visits should happen after the secondary contact visits). read more
