Do you suspect you’ve already had COVID-19?

Do I think or suspect?   Not sure but it is possible, I'll go that far.

A friend and I both had the same thing and then later my DS;  in mid February.  Something like a sickness none of us had ever experienced. 
I ended up overnight in ER getting IV drips and labs taken.  I felt worse in that period of than when I had my kidneys removed, it was awful.  It was deemed a virus but what kind who knows.

Now that you mention the toe thing, had similar but because of chronic condition and medications it's really hard to trace it all back, isn't it?  Strings attached from symptom(s) to cause would be helpful but unfortunately it doesn't work that way.

So the best I can commit to is who knows/possible.

I do. I was SO sick in February. I had the worst cough, had trouble catching my breath, fever. I was in bed for days. I went to the dr and tested negative for the flu and strep. My husband was sick after me. Same symptoms but had a higher fever. DD got it to but hers wasn’t nearly as bad.

No. Somehow we managed to come out of December-March with only getting sick with fevers for a few days. Usually we catch something that will knock each person out for a week each during that time.

No, I (knock on wood) have been pretty healthy all winter. Members of my family were very sick all throughout Jan and Feb, and several of my students were really sick, but I don’t know if if was just the crud or covid.

I thought I did back in March because my oxygen level dropped significantly when I was sick, but I had the antibody test and it came back non reactive

No, I haven't been sick at all.

My husband was super sick with something weird back in early March. He got tested a couple of weeks ago, and he doesn’t have antibodies, so it was something else.

I doubt I’ve had it.

I had something in January that knocked me on my butt. I thought I was coming down with sinus so I got some Mucinex D which usually works great. It did nothing. The next day I felt really weak and exhausted. It took me until mid afternoon to drag myself to urgent care.

They told me my oxygen levels were really low, did a test for the flu which came back negative. I was diagnosed with a sinus infection, dehydrated and pneumonia on my left side. I missed 3 days of work, something I have never done before. Even after finishing my medication, I had a cough that lingered for weeks and just felt so tired. It took a good month before I had any energy or felt like myself. I've never been that sick in my life.

My kids were just tested today. Back in Feb. they both had sore throats, mild fever, and my son developed a rash. They were tested for Strep and both were negative. Doctor said it was just some random virus and sent them back to school since they didn't have a fever anymore. Now that more has come out about the rash and kids with Covid, the doctor is suspecting that maybe they may have had it. They had their physicals today and she ordered the test. I think we get the results in a week. I had something in March that really I thought was just a seasonal allergy attack/cold but then it went to my chest and I couldn't get a deep breath. I never had a fever or any of the other symptoms. But the breathing was bad for about 3-4 days. Doctor ordered me a steroid pack. It got worse before it got better. I'm going to email my doctor tomorrow now that Kaiser has approved an antibody test. We shall see.

No...definitely not.

About 3 years ago I had a bout with a flu, I needed two weeks off work, then I got really bad asthma and needed Ventolin nebulizers as well as a course of steroids. I usually walk home from work and couldn't do that for over 3 months. I had a cough/asthma for months afterwards. It's only the second time in my life that I've been that unwell, the last time I was in my 20s.

There was no corona virus around then,...that's my point, if you get a real influenza virus (not just a bad cold) then you do get really sick and some people get sick enough that they die. That happens regularly and it happened before anyone ever had corona virus.
So just because you got really sick with a flu virus in winter, doesn't mean it was covid-19.

My daughter thought they did in her house back in feb with flu symptoms but no flu, but tested neg for antibodies. The covid toes sounds like you may indeed have had it in your household. 

No.

Nope. We've all been super healthy here.
My friend returned from a 6-week business trip to India in early Feb and got really sick with fever, loss of taste and smell, lingering pneumonia that responded poorly to steroids, and dry cough that lasted a month. That was before testing was available, but her doctor is pretty sure she had it. Probably caught it in one of the airports she went through on her 5-leg flight home. She just went for an antibody test yesterday, so we'll see.

I have been approved for a Covid antibody test next week. If it's negative it won't prove that I haven't had it because not everyone makes antibodies. But if it's positive that will answer a LOT of questions.

Can you get reliable antibody tests where you are?
