This was as a result of recent understanding that the virus can reside further down your throat, or nasal passages. With that newfound information, they are now swabbing much further down the throat/nose.
Kind of scary though, there might have been cases where the person tested negative and was able to be out there in the population. I wonder how many other hospitals throughout the world were making that same mistake in the initial stages?

They had the exact same problem very early on when it was mostly just China and HK and SG. They learned that they had to jam the swab way in to test properly, since it's a deep infection. I just thought the graphic image of it was interesting
I thought it would have been common knowledge by the time it became a pandemic... If a geek like me knew about it months ago, why didn't the people doing the tests?
