Not reading the thread are we?
There's a lot about Iceland that other countries could envy: Its spectacular natural surroundings, its place among the world's happiest countries, and, now, its large-scale testing for the novel coronavirus, which could influence how the world understands the outbreak.

Anyone who is an asymptomatic carrier recovers in about 10-15 days. Serotype testing for antibodies can confirm this status.
I know this thread is long but come now:
I have it linked to the correct time for you. "82% of cases have symptoms that are mild" according to earlier data. I've seen this repeated often, and I see little evidence to suggest otherwise. Taking the two bodies of evidence together, it seems that 50% of cases show no symptoms, ~30% of cases show mild symptoms typical of other ailments, and ~20% of cases develop into something potentially worse.
It's actually easier than you might think. At this point in the game, serology testing is more useful for those who have no symptoms. It tells us the exposure rate among the population that has not required hospitalization. With few exceptions, covid-19 has been spreading since mid February in the United States, if not earlier. Many of those who a). have sheltered in place and b). not been hospitalized have already had sufficient time to excise the virus from their system (remember: it takes about two weeks to recover when asymptomatic or when symptoms are mild enough that the immune system isn't busy punching holes in lung tissue). In other words, by this point, if you have no symptoms, you've either never had it or odds are very good that you aren't capable of spreading it anymore.
I fully expect most states to maintain the current stance until April 30th. Some locations may take longer. By that point, the odds of actually contracting the disease from people who aren't actively displaying symptoms will be a lot lower than they were just a few weeks ago.
Increase serology testing would give us some idea of those who are still vulnerable in the population and those who are not. Those who already have antibodies are generally pretty safe to be around if you've already got them yourself, and beyond a certain point in time (which arguably we've already reached), the vast majority of those with antibodies will be safe for those without them.
