Tracking technology is too effective not to use. A two week incubation is catastrophic for containment. It seems that most countries have given up trying, before it's even begun - only Singapore is doing exhaustive contact tracing and testing. The standard of testing and isolation in western countries (looking at the US and UK) is... poor. Imagine if this disease had a 100% fatality rate - it would be apocalyptic and we would be powerless. Privacy and control of information is a huge concern. The correct architecture for this, in my opinion, is exhaustive local collection of location data, followed by subpoena on confirmed diagnosis. Once you've been proven to have been walking around town infecting people, other people's right to know they've been exposed trumps your right to location privacy (although the data need not be tagged with identity, we must assume that the level of detail required to make it useful would deanonymize it). Everybody can check their local tracks database against the public record of exposure hotspots, and get themselves tested if they've been exposed. The biggest challenge with a system like this is making sure the people in charge of it are trustworthy, and persuading people that it's in their interest to participate in it.
