Contacts Dashboard

The overview can also be displayed for the contact situations by clicking on the contacts field at the top right. The contact overview contains various data on the contact situations recorded for the current outbreak, based on the date they were reported.
Period under review
The period to be viewed can be selected directly under the heading Contact overview
(A). A comparison period can be selected to view the data in relation to the previous period. The preset period is initially "this epi-week" compared to "the previous epi-week". This epi-week always covers the period from Monday of the same week to the current day. Further options can be selected by clicking on the relevant button (see section 1.1.1).
Key figures on contacts and tracking
In the row below the period under consideration (A), there are various key figures on contact situations and tracking (B). From left to right in this row:
1st block "All contacts": Overview of all recorded contacts in the period. This is broken down into unconfirmed or confirmed contacts as well as newly recorded, symptomatic or no contacts (e.g. if it was subsequently discovered that, contrary to previous information, there was no contact after all). A contact is considered confirmed if an appropriately authorized person (the contact person themselves if they are of legal age, legal guardian in the case of children, etc.) has verified that there was actually a contact situation with an infected person.
2nd block "In the follow-up": Overview of the current status of the follow-up, broken down by willingness to cooperate (has the person provided information) and status(was the person reached or not reached). Also a display of how many contacts were not called in which period.
3rd block "stopped follow-up": If a follow-up is canceled, for example if the contact has been converted to a case or because it turns out that the disease is not COVID-19 after all, this is listed here. If follow-up is not possible at all, for example due to incorrect contact details, this is also displayed.
4. block "visits": Overview of the visits/ calls recorded in SORMAS, broken down by willingness to cooperate ("cooperative", the person provided information, "uncooperative", the person did not want to provide information) and status ("n unavailable", the person was not reached). The number of all calls that were not made in the period under review ("Missed") is also listed.
Directly below this are key figures on the average (as well as minimum and maximum) number of contacts per case, contacts in quarantine or those who had to go into quarantine for the first time during the set observation period, as well as new cases that were not previously known as contacts (C).
Follow-up Status Chart
Similar to the graph of the epidemiological curve in the surveillance overview, the lower half of the contact overview contains a visual representation of the follow-up situation (D):
The last seven weeks are shown by default, but other groupings are also possible here (see section 1.1.5). The coloring of the individual columns is shown in the legend above the diagram. The chart is equipped with a so-called "mouse hover effect", i.e. individual categories can be highlighted by clicking on the individual bar segments or by simply pausing with the mouse on the respective segment. The highlighting also takes place when the mouse is moved over the legend. This is shown in the illustration above. Click on the two arrows pointing apart at the top right to enlarge the illustration. Below this, in the field with the three gray bars, the figure can be printed out or an export of the selected data can be requested, either as a figure in various formats (png, jpeg, pdf) or in the form of raw data (csv, xls).
Contact Map
To the right of the tracking status diagram is the "contact map" (E). Here the map material from OpenStreetMap is used, all entries remain on the your own SORMAS instance. In this map, the contacts of your own administrative district/city district displayed. Contacts are always displayed if, after entering the complete address data, the so-called "geo-button" was pressed at the appropriate place, which calculates the GPS coordinates from the address data entered and transfers them to the map (the geo button is discussed in the chapters on cases, contacts and events).
Just as in the tracking status diagram, the contact card can also be opened double arrow on the right above the map. The card can be zoomed in or out. Clicking on the symbols shown on the map, which are explained in the legend, opens the corresponding contact file in a new browser window.
In addition to the legend, there is a button for different "layers" below the map. Click on this field to open the selection list. As with the case status map (see section 1.1.5), various filters can be applied to the map to display more or less information.
Disease Network Diagram
By clicking in the contact overview on the field "Please enlarge to see the infection chains of the disease" (F - see upper figure) below the "Contact map", a new view with the disease network diagram opens (see lower figure).
All cases and contacts are displayed here according to the color coding of the legend shown on the left (A) and the relationships between them. Directly under the heading "Contact overview", the period to be viewed and the comparison period can be selected (B). Different connecting arrows represent the respective risk of the encounter. For cases, i.e. infected persons, the corresponding case ID, which is automatically generated by SORMAS when a new case is created, is shown below the figures. The figures in the graphic can be moved and detached using drag & drop (click and hold the mouse). The people who were in contact with each other remain connected by arrows. In this way, connected clusters can be visually identified. A distinction is made between high and low risk (contact category I and II). Dotted arrow connections represent a low risk. All green figures represent persons (cases or contacts) without symptoms.
