This is a theory some have put forth based on the lack of information we have about this particular virus. Since we don't actually know, anything is possible. However, it is highly likely you do become immune after having it, since that is how most viruses we know of work. Nobody knows for how long you would be immune and it would vary from person to person. It could be years. The worst case scenario is nobody can become immune, in which case nothing we are doing would matter as far as I can tell. But that is unlikely. Next worst, you can become immune but only for a short time (months rather than years.)
Worst case scenarios are scary, but in all likelihood, you will develop some immunity if you recover from Covid-19.
The test detects protective antibodies to the virus rather than the virus itself.
This gives scientists a snapshot of how many people in the county have already been infected, but weren’t seriously sick and didn’t realize it. And it tells residents whether they carry potentially protective antibodies – so may be immune to future infection.
Is this basically saying either "Yes you have it and are cured" or "Yes you currently have it"? Or because of the antibodies does is just mean the former?
It means you have had some immune response to it. That could mean you've fought it off and have recovered, or it could mean you are currently still battling it. You should be able to tell which based on whether you still have symptoms.
There's none. It says:

Hope this one works. A few weeks ago the UK government said they were testing some kits from a range of companies claiming they could do this. Recently they noted that the tests were wrong I think 25% of the time. A test that is not reliable can be worse than no test.
They say that your body creates antibodies within a few days of being infected. There is no solid proof of how long the antibodies last in your body, but they hope it’s a few years similar to other flu strains.

Understanding COVID-19 Antibody Test Results
What is the test?
This test looks for coronavirus (COVID-19 or SARS-CoV-2) antibodies in your blood.
Your body makes coronavirus antibodies when you have the coronavirus.
Antibodies stay in your blood after the virus is gone.
How is this test different from the nasal swab coronavirus test?
The nasal swab coronavirus test looks for the actual coronavirus in your body.
This antibody test does not look for the actual coronavirus. It looks for antibodies which your body makes.
Why do we need this test?
We need to know how many people in our community have ever had this virus. Hospitals and public health need this information to make sure we have enough supplies and staff to take care of our community
What does this test mean for me?
No matter your result, you should continue to follow the shelter-in-place order and all the other recommendations of the Santa Clara County Public Health Department. You can find the recommendations on the back of this page.
I tested negative. What does that mean?
A negative result can mean one of these three things:
You have never had the coronavirus (COVID-19 or SARS-CoV-2). You can still get the virus in the future.
2.You got the virus in the last 7 days. Your body has not made antibodies yet, so the test did not
There is a small chance that the result is wrong and you actually do have coronavirus antibodies.
It is very important to continue to follow the shelter-at-home order and all other recommendations of the Santa Clara County Public Health Department. (See the last page of this guide for these recommendations.)
I tested positive. What does that mean?
A positive result can mean one of these three things:
You got the coronavirus (COVID-19 or SARS-CoV-2), and then you recovered. Scientists do not yet know if this means you can get sick again.
You currently have the coronavirus (COVID-19 or SARS-CoV-2). You may have gotten it at least a week ago (so you had time to make antibodies). This also means you could infect others.
There is a small chance that the test is wrong and you have never had the virus.
If you develop symptoms, you should seek medical care. Tell your doctor you tested positive on an antibody test. You should continue to follow the shelter at home order and all other recommendations of the Santa Clara County Public Health Department. (See the last page of this guide for these recommendations.)
