These are exceptionally cheap w/ very good accuracy to detect people when they are carrying infectious virus
Extremely easy to use
Simple design
I suggest a model where you reuse the plastic shell (like contact lenses) and just change the paper strip. Simple.

It is really unfortunate though that this particular test is NOT sold in the US. It is sold outside of the United States.
Nevertheless - this is to show that THESE TESTS EXIST.
The US Government should be making them in the 10's of millions daily.
Instead, Americans are dying
To use these... take self nasal swab - just front of nose (like you're picking it - not painful). Then put swab in a tube with a liquid. Then put 2 drops of the liquid in the circle on the test... liquid flows across (lateral flow) and a line forms if pos - like a pregnancy test.

Right... lets keep focusing on PCR lab based medical testing for a public health war
A public health test with a:
-24 hour delay is just OK
-48 hour delay really losing its use
-72 hour delay almost irrelevant for transmission
-96 hour delay - waste
68,671 cases
Pop: 885,000
HIGH test +ve %; i.e. not nearly enough testing
I'd be surprised if catching >1 in 5 cases
If so, does 68,671 => 343,000 cases?
And if so... 39% infected...is SD nearing Herd Immunity?
Should serosurvey much of SD to understand if so.
Note: It's tough to know what the true detection rate is. Is it 1 in 2, 1 in 5, 1 in 8 detected?
We don't know for sure.
Either way... SD has a LOT of it's pop infected.
Since it's one of highest per capita states, will be imprtnt to monitor this state
And no - I am NOT suggesting herd immunity as an option. I'm simply stating the numbers up there and suggesting that we monitor to better understand what has and what will happen.
First, the amazing efficacy from phase 3 at this point for both @moderna_tx and @pfizer vaccines - both mRNA vaccines - is EXCEEDINGLY ENCOURAGING.
These results show that these vaccines are eliciting the correct antibody bases responses to stop symptomatic infection!

What I am worried about is the time scale of the trials thus far:
The leading vaccines are presenting the spike protein to the human immune system. This makes sense! Immunize against spike and stop virus entry into the cells.
