Infections happen within families, and spread from one family to another by friends/coworkers. The infected people should be easily able to list all exposed out by name.
An exception is of course mass indoors public events that are forbidden now. This is where a contact tracing app would probably prove to be the most useful.

- Retric 6y agoIncidental contact is unlikely to matter in most cases. However, multiple people at different tables where infected at a restaurant from a single customer. So, it doesn’t take that much.
- eloff 6y agoOr on public transport. New York's subway system was probably it's Achilles heel during this outbreak.
- dehrmann 6y agoExcept Staten Island had the second most cases per capita. Lots of the obvious NYC theories have holes where you look at places affected.
- jmull 6y agoPeople who live or work on Staten Island used mta services, including subways, heavily.
- adrianmonk 6y agoMaybe ferries cause the same kinds of problems as subways do.
- cozzyd 6y agoYes Public transport is probably the best use case for contact tracing. A combination of location history and fare card data will work for buses. For trains it's a bit trickier since you want to resolve that you're in the same car, and Bluetooth would work well in this case.
- cma 6y agoHow about that restaurant study where lots of people at tables behind the guy next to the air conditioner flow got it: https://www.nytimes.com/2020/04/20/health/airflow-coronavirus-restaurants.html https://www.nytimes.com/2020/04/20/health/airflow-coronaviru...
- bhelkey 6y agoI see these methods as a way to capture in depth contact between strangers (Public transportation, Lyft/Uber, ...) and to double check our memories.
