I think casual contacts wouldn’t be notified - like drive-thrus, somebody you passed briefly on the street or in a grocery store. At least that’s how it will work in Louisiana.
The state’s plan considers people who have been in close contact with someone if they are:
- Household members of the person who tested positive
- Intimate partners of the person who tested positive
- People who have provided care to you in the household or outside
- Anyone who has been in close contact – that is defined as someone who has been within six feet or closer for a time period greater than 15 minutes
Here's how Louisiana contact tracing would work under Edwards' plan
But that's not how it works in other places. The more places a CV+ person can remember, the better. In those nations/states where resources are put into that kind of contract tracing, the rate of CV can be contained quickly
There's one person (I can't remember where) who infected 533 others (some directly, some from the direct infection). ALL of those people (most of whom are asymptomatic) need to self-quarantine, as it's unknown how many people are passing it on cryptically.
Household members, for sure, right? And yet, hospitals do not even ask that information regularly or if the patient doesn't want to give it.
No hospital that I know of is asking CV+ patients for every sexual partner they've been with, nor have I ever been asked that in any in-hospital study I've been in. I suppose LA is asking people to think about this - but surely they aren't going to put people in jail/quarantine for failing to list their sexual partners.
The last one is of course a stab in the dark. If the patient can remember - great. Usually, patients can remember caregivers, IMO. But every person they've been in contact with, for 15 minutes or more? Wow.
When I first self-quarantined, I spent 21 days worrying about all these things. I have 300 students or so, I went to meetings, I got gas, I went to the grocery store. I couldn't even remember offhand which stores. I walked past a taco truck and had to wait for a light, so I was there for 4 minutes or so - yay? But I walked through the same group again later, another 3 minutes of waiting for the light to change? Was that enough to report?
And I'm a good observer. I take pictures a lot, too. But I can't remember who I might have talked to in the halls or the parking lot for that period. I do remember, on my last day, fist-bumping a dear friend who had lost access to chemotherapy, due to Co-Vid. There were others there - we were there for far more than 15 minutes, but I don't remember.
So...to get the information from me would probably take an hour or so, with me forgetting some of it. An hour per each contact.
We all got such a late start on this, I am desperately hoping each State will catch up. California has a mandatory notification of a patient's workplace, but so far, isn't investigating much further - we'll see how that goes.
I would really really appreciate if you update us about how this really goes down in Louisiana - and best of luck. The latitude of Louisiana and SoCal may, in the end, be what saves us.
