Many of us are getting exposed to people with (+) tests. What to do?
Think about the numbers below if you want to get tested.

How likely you are to get a false negative result:

100% day of exposure
70% 4 days after exposure
40%. 5 days after exposure
20%. 3 days after symptoms develop

Exposure is defined as being within 6 feet for more than 15 minutes without a face covering when that person was symptomatic or in the 48 hours prior to them developing symptoms.
If exposed stay home and isolate for 14 days.

What if it was windy? It is infuriating that we screwed this response so bad that we have define exposed this narrowly to prevent overwhelming our testing capabilities more than they already are.

Okay so how does my case line up.

Wife and i are around 4 Infected persons for 5 hours last Saturday. These individuals tested positive on the swab a week later (this most recent Saturday)

Wife and I get rapid nasal swab yesterday and both antibody tests with finger pric#

We both test negative for everything across the board.

Reliable results we don't have it?

Are you showing symptoms?

Slight sore throat but that's it.

How do you know for sure they were infected when you were around them if they weren't tested for a week?

What about secondary exposure?

Hang out with person A who found out after being around you that they were previously around someone who received a positive (but didn't know that until after they were around you).

What's best practice?

Good question. Long story but infected person didn't really see anyone else between that day and when she got tested positive besides her husband (he tested negative)

When did they start showing symptoms?

Wednesday/Thursday

Do you have a source for those numbers doc? I'd like to update our corporate policy if so.

Thanks in advance.

Also wondering this:

Is there an explanation of why 20% day 3 and 70% day 4? Then down to 40 % day 5? Seems odd that day 4 is that much higher then day 3 and 5. Thanks for info.

The 20% false negative figure is 3 days after symptoms begin, not exposure.

Bullard21k - high likelihood that you are safe. For an asymptomatic close contact, days 7-14 post exposure is highest likelihood for detecting viral DNA via PCR. However it would still be wise to monitor yourself closely for symptoms, wear a mask, wash hands, minimize close contact with others for another 7 days incase it was a false negative. However you should be doing all that anyways to avoid someone else giving it to you. In the case of your sore throat, take some allergy meds and sudafed and see if it gets better.

Katlong - As of right now there is no indication that I'm aware of that close contacts of close contacts need to isolate. However close contacts should be tested, and if positive, then the close contacts of the close contacts should quarantine and get tested depending on how the timelines align. This is essentially what DoD policy is right now. But as always, monitor yourself for symptoms.

I see. I knew I was missing something. Thanks again.

I'm really confused. So if I wait 5 days from my exposure, I am still looking a 40% chance of a false negative?

If that's the case, what if any benefit is there to getting tested while asymptomatic?

I get it. But on the other hand, do you want a PD that has an entire shift or a large majority of a shift out with this?
And there's also a varying degree of "exposure". Just having been close to someone shouldn't necessarily be a 14 day stay at home. But having worked with 2 people in an office space for 2 weeks who tested positive is a little different.

I was referring to the OP who was making a generic statement. I understand PDs and other businesses may have different situations.

But as a generic expectation it is a loser.

Aside from the knowledge, the benefit is even further reduced by the fact you likely won't get test results back while relevant. Took my daughter is Dallas 10 days to get negative results

My wife got tested on day 3 of her symptoms (fever, lethargy, getting tired quickly, achy muscles, cough). It took 12 days to get the results of her test back. She had symptoms for about 10-12 days.

Today her results came back as negative. The doctor admitted she probably had it and that there was a high false negative rate that could account for her negative test result. He suggested she come back in for anti-body testing and another molecular test. However, I don't really see the point -- it doesn't really change what we do or how we act. We have been isolating since her first symptoms and it's been 2 weeks now. I did go ahead and get a test for myself, just to make sure I am not an asymptomatic carrier.

I understand why many doctors here have been skeptical about going to get tested. Even if we had gotten the negative result in 1 day, it shouldn't have changed our behavior and isolation.

I don't really understand the whole testing thing at all. Why get tested at all? If you're sick, stay home. If you get out of breath going to the bathroom, then go to the hospital. Seems like testing is more of a boondoggle to the urgent care centers than anything else.

I'm going thru this right now. And I completely agree with you.

It would be one thing if they were easy, reliable, quick, and accurate. But they are none of those things.

And how can we expect people who are not sick to take 14 days off work? That's crazy.

---

Again, like we discussed before, that's likely totally dependent on what line of work. You're lumping all jobs into the same thing and they aren't.

Maybe you have a job where you roll around mostly working alone in your truck....... fine, no reason for you to not work for 14 days. You want to take a person with a known exposure and pop them into the office, right next to the rest of everyone else in your business? Great, so instead of possibly just being one person down, you're potentially down many more. How is that good for business?

I imagine if those meat packing plants had been able to send a handful of people home instead of just having em all "come on in to work" things may have gone better.

My daughter did the swab on Friday 7/3, we got her results first thing this morning 7/7 in Dallas from a private lab.

Much better then our experience! Glad for you.

20%. 3 days after symptoms develop

So, where do these exposure guidelines come from? Most specifically the Pre-Symptomatic exposure. I was around someone 3 days prior to them developing symptoms and testing positive. Should I be concerned and self quarantine? would I be prior to the typical window of that person being contagious?

I really tried to look this up on the CDC site and either I don't know how to search the site or it is not there. Any help would be appreciated.

How close and long lasting was the exposure? Since symptoms can develop 2-14 days after exposure it is quite possible you were exposed. My official recommendation would be isolate. My practice tends to be the sick and old so I make every effort in protecting them. Be smart and considerate regarding whom you are around. If you have to go to work always mask around others and keep your distance. Minimize individual contact- brief and at a distance at a minimum. None is better. If you can't do that don't go. Seems extreme but no other way to stop this thing.
The reality is it is impossible to know for sure and we have to give advice every day. Exposure can vary by so many factors that are unknown. Maybe some day there will be a series of questions that generate an exposure "score" then I can have more certainty on infection likelihood. Not present yet so 14 days it is.

So I assume that social distancing is the ticket out of this thing long term and to stay negative in the short term. Seems to me that if you limit your exposure, indoors for longer than a brief moment, you will probably come out on the right end of this. When you start getting yourself involved, indoors, with lots of people for an extended period of time is when you can get in trouble.

I wear a mask because they make me. But I have this social distancing down, and it seems to me that so do most other people I run into. I have been indoor with the same person for more than ten minutes maybe three times since spring break. And that was still well distanced at taquerias for lunch. Thats it. Maybe one other time with some contractors.

I am going to have a hard time getting it as long as I dont get it from kids.
