I was just watching The Today Show and Dwayne Johnson, also known as The Rock, was saying that he had a message because he got coronavirus from his close family and friends. He said to everyone if you are going to have family or friends over, make sure they get tested the day before they come to your house.
Hello! Hello! Normal people can't get tested and get the results within 12 hours.
It's becoming more common, though. HI has a commitment to fast testing and here in California, we're seeing faster returns than we did a month ago. Supposedly, in my county, test results are given within 24 hours - I only know a handful of people who have been tested in the last couple of weeks, but they got their results by the next morning after they gave a swab in the afternoon.
I know some people in the US are still reporting that they have to have a doctor's order to get the test - or that they're being charged for it. But here where I live, it's all free, there are multiple testing sites, the weekend one at the college gets results to people within 24 hours (and has been doing that all along). One does not need to have symptoms to get tested here and there are whole blocks of time during the day where there's basically no line.
HI has closed down a segment of freeway, IIRC, to make testing from cars quicker and more easily available. Keep in mind that HI has a small population. Only 1.5 million people. As an island that has had many diseases from off-island sweep through it over the last century, people are keen to get CoVid under control.
Anyway, "normal people" where I live in CA and where my family lives in HI can get fairly rapid test results. Dwayne's comments are probably based on that. I believe he lives on Oahu - but I could be wrong about that. He may be in CA for all I know.
Friends in Massachusetts and New York also report rapid test results - but they live in big cities, might be different outside of Boston or Manhattan.
A 12 hour return of results would be great, but if people got tested in the morning the day before an event, they'd have 24 hours for the results.
