I beleive there is also a lack of literature on how useful a contact tracing app would be in the first place. Even for lack of studies, releasing the modelling and assumptions would be useful. Some considerations: * Possible increase in false positives bogging down testing regime? * Surface-based (i.e. location-based) contact events (e.g. elevator button) * Effectiveness on health-care workers, who themselves will likely be in contact with infected people a lot, perhaps despite having sufficient PPE. I get that it won't be perfect, and doesn't need to be perfect, but I'd at the least like to see some modelling to see what they've considered, and how likely useful the app will be.
