I don’t think this is reliable enough if you like to stay safe while being out, although it seems better than nothing.
Considering that aerosols are a plausible infection vector, it becomes necessary to introduce air flow models that include building ventilations for a reliable outcome of location based monitoring. Honestly, I consider this a major, and quite risky undertaking. Already a retrospective analysis of who-infected-whom based on location will turn out quite incomplete.
As a side note while being quarantined at home: please consider closing building ventilations, talk to your neighbor to coordinate asynchronous window opening procedures, and ensure closed sewage systems.
Why do I come to these conclusions?
1. It is plausible that SARS-CoV-2 behaves like SARS-CoV-1 in aerosol transmission. https://dx.doi.org/10.1056/NEJMc2004973 https://dx.doi.org/10.1056/NEJMc2004973
2. It took quite an effort to find out how SARS-CoV-1 spreaded from one single flat to other flats and to nearby buildings that were located in the direction of wind. Indeed, it is assumed that sewage ventilation played a role here.

- gjs278 7y agohi i’m your neighbor would you like to coordinate our window openings? fucking lol
- dennisy 7y agoSorry for what is probably a silly question, but are you saying someone can be infected through an open window?
- jmalicki 7y agoIn the second study, they are claiming that people were infected through their building's ventilation.
- xenonite 7y agoYes, please see the discussion in the second study. They cite the findings of an investigative team of the WHO for the infections in the same building, and add their own findings to explain infections other buildings (which the WHO didn't explain). And yes, both the WHO and the study states open windows as inlets for the aerosols. In my opinion, this also explains the measures in China: here a whole building is evacuated and quarantined if one single person in the building is tested positive.
