In the sense that they requested 1,000 volunteers, and 400 signed up? Do you mean it's a selection bias due to only a certain kind of person who signs up for these things getting tested?

Yes, correlation between suspicion of infection to volunteering to testing positive. If they wanted to know how many felt symptoms they would survey them. Wouldn't jump to conclusions.

People would sign up if they suspected they had coronavirus based off of their symptoms.

This comment thread is about antibodies.

There was a different line of testing for who actually had the active virus/disease which included far more sailors from the ship:

> As of Monday, the Navy had tested 94 percent of the crew for the virus, with 678 positive and 3,904 negative results.
