Here are their "jobs to be done"

I WANT TO find the person's contact info
SO I CAN make sure they can isolate themselves and elicit their contacts
There's substantial transmission early in COVID infection-> getting infected contacts quarantined before sx is key to containment
Here's one from @QuestDX for hospital patients: name, sex, dob, address (and of course, hospital info)
For outpatient: SSN, phone# are sometimes filled out. Also lots of insurance info :-)

What if they could use the best commercially available tools for getting phone #, emails, addresses, handles?

What if public health could request the standard clinical document on these patients. We are close!
Well, we have a lot of empty hotel rooms, and a lot of former hospitality industry workers who'd be great to help navigate people through this

WHEN I interview an index case
I WANT TO review their location and travel history
SO I CAN jog their memory of people they may have exposed
kind of like... this?

WHEN I interview an index case
I WANT TO identify all their contacts
SO I CAN reach them and get them to quarantine ASAP
This is the step that we have been building up to, which is going to decrease R(eff) and help us get out of lockdown- safely.
Only works with trust
Fortunately, the number of contacts the average person has on the downswing of the outbreak coming off lockdown will be a lot fewer than it would have been on the upswing.
For me, it's 5
So WHEN I identify household contacts
I WANT TO talk to them right away
SO I CAN reinforce the messaging for what they are supposed to do now (eg quarantine)
We may ask index case if they are willing to be identified or not.
We may give index case tools to do notifications themselves?
#Protocols
WHEN a contact becomes symptomatic
I WANT TO be notified
SO I CAN get them tested and if positive, initiate contact tracing on *them* (GO TO 10)
Could be through fancy telemonitoring devices, or low tech
maybe even preposition swabs and mailers
But again, should come from a place of "what do you need" rather than "why are you a bad person"
Hospitality workers, census workers, bartenders, (journalists) would be terrific
