• It can be in close proximity to a mosquito collection point, larval dipping site or a structure
• It can be within or outside of an operational area
• It can be a distinct thing next to a residential structure
• Identifying PAOTs  is part of the Thai protocol and is currently done on hand-drawn maps
• Dropping a point for or editing a potential Source area of Transmission should not be restricted by GPS proximity (unlike interaction with other structures)

Requirements

1. OVERVIEW: A user should be able to add an icon (possibly similar to the image of Plasmodium Gametocyte below) to TBD) to the Reveal Android map showing a Potential Area of Transmission (PAOT). 
2. FORM FIELDS: The user should be able to add a comment to the PAOT form (not mandatory) - maximum string size tbc (2000 chars? this should be the same as other comment fields in Reveal) specify the type of PAOT from a drop-down (list to be provided - 'Pond, Cave, Forest) (Pedro Pagalday Olivares to confirm this please)
3. FORM FIELDS:
   1. The comment field (task/form) should be editable Craig Appl - can you verify that each time this data is saved that a new form is submitted to the server (same data workflow as mosq collection point & larval dipping).
   2. This is the The date that the PAOT was recorded - this field is mandatory. Each time a PAOT is identified during an FI this data should be recorded .and displayed on the card view
   3. We should be able to see a historical view of the comments & dates recorded as a PAOT in the web UI & supersets.(low priority)
4. REQUIREDNESS: It is not mandatory to add a PAOT to a focus
5. LIFECYCLE: The PAOT will persist across subsequent FI, but should be able to be removed (set to inactive) I.e. they do not expire
6. LIFECYCLE: The addition of a  POAT to a focus area will, in general, be a .once off task performed during the first visit
7. USAGE: The PAOT data should be synced to the Reveal WebUI and be visible in the Web UI maps (high priority)
8. USAGE: The PAOT data should be as a line listing reports (to be mocked up) (low priority) - the comment should display when clicking the POAT icon in the WebUI
9. USAGE: The PAOT should be synced to Biophics in the same way that other tasks are (high priority) - this is where the BVBD will analyse the data
10. PLANNING: The PAOT activity will not be part of a plan activity
11. TASK STATUS: The PAOT can be coulored yellow when it is created:
    1. Once selected and the data comment field is filled out, the color will turn to green for status of 'Completed'.
12. LINKAGE: One focus area can have multiple PAOTs
13. LINKAGE: The PAOT is associated to a focus area and not explicitly to an Index Case. This linkage can be assumed through the 1:1 mapping of focus area and index case per plan. However, the PAOT is not necessarily related to the index or secondary cases in the focus i.e. it is A a potential area of transmission, not THE  THE potential area of transmission for the cases in the focus at that time.
14. EDGE CASE: A PAOT is NEVER another type of structure, and if a structure is identified as a potential source then a PAOT should be added alongside the existing structure
    1. A potential issue raised is what happens with very large structures (Markets, football fields) as PAOT cannot be dropped on top of this - Vivek confirmed that this was discussed with BVBD and placing a pit next to the structure with a comment is sufficient

• Vivek - purpose: for targeted interventions, could visually see if there is a correlation of infection for more than one focus. they do this on paper at the moment. It is a critical piece of protocol for the Thai team.
• Was this mentioned in the initial first visit? To confirm with Pedro
• Data should be surfaced in web UI and pushed through to Biophics (not for this version though) 
• You need to be able to define an area of transmission as part of the focus investigation

Questions

1. This feature has been described as a Potential Source of Infection (POI) and a Potential Source of Transmission- which is correct?
   1. Confirmed by Vivek Agrawal as Potential Area of Transmission (PAOT)
2. Was this requirement mentioned during the initial first visit? To confirm with Pedro
