Protocols for Bluetooth contract tracing are being designed to be frictionless and not allow other humans to be involved. I think that's wrong. Protocols should anticipate and enhance effectiveness in systems that include public health workers doing contact tracing. 1/6

I understand that it might not happen immediately. It will take time to hire and train the people we need to do contact tracing. The JHU plan on contact tracing suggests we will need to hire 100,000 people to do contact tracing. 2/6 https://www.centerforhealthsecurity.org/our-work/publications/2020/a-national-plan-to-enable-comprehensive-covid-19-case-finding-and-contact-tracing-in-the-us

A Bluetooth contact tracing protocol should collect info that allows human mediated contact tracing to be more effective, and might collect information that is provided to public health worker and be revealed to contact only as necessary for the system to be effective. 3/6

I've already spent hours working on this and talking with some health care professionals. Pages of notes about the issues and challenges of doing this well and securely, and how it could improve effectiveness of contact tracing. I want to develop this further off-twitter. 4/6

The Apple/Google and the #DP3T protocols could produce information useful for enhancing traditional contact tracing, but current APIs don't expose that info to apps. It would be good to think about this now, rather than try to add it a few months down the road. 5/6

Reaching out to people to discuss this with off-twitter; looking particularly for people with experience in health care policy, epidemiology and traditional contact tracing. Could produce joint document, or just inform and enlighten what I put together. 6/6
