It’s to do with the likelihood of a positive result on the test.
A sneeze can spread it to ten people but that could take weeks. If they want it to show up on a square 5 millimeters of Cotton they have to get pretty close to the source.

But they are saying everyone needs to wear a mask so asymptomatic people don’t spread their germs through coughing, sneezing or speaking. Wouldn’t that mean the infectious germs are present in the mouth?
And it’s not a nasal swab, they stick that sucker into your sinus cavity from the demonstrations I have seen.

I guess it can be in the mouth since when they tested my father they did a throat swab. I heard he nearly gagged. Isn't it the same with strep? They have to swab pretty far back.DSamuels wrote: ↑Sat Jul 04, 2020 6:37 pmBut they are saying everyone needs to wear a mask so asymptomatic people don’t spread their germs through coughing, sneezing or speaking.

No, it’s basically the same when collecting for a flu test. Not comparing COVID to the flu, but the specimen collection is similar if not the same. And there is also saliva tests being studied now, so maybe specimen collection is changing.

How are these even related? It's like something a child would ask.
Have you ever wondered why Tuberculosis is spread through the air when the infected person coughs, sneezes or even speaks, but we need to test through blood? No.

Well, well, well
Rapid sputum tests are also called nucleic acid amplification tests (NAATs). One of the best ways to diagnose TB is through a sputum culture. A sputum culture is a test to find germs (such as TB bacteria) that can cause an infection. A sample of sputum is added to a substance that promotes the growth of bacteria.Feb 11, 2020

Point is they can test through blood. Just because a disease is transmitted through the air via air droplets doesn’t mean the best way to test is through droplets.DSamuels wrote: ↑Mon Jul 06, 2020 8:16 pmWell, well, well

I’m sure they’ll have a simpler test in time. And a more accurate one. Still a childish question.
