1) If a person is self isolating in case they have it then a negative test would allow them to return to work and a positive test would allow a trace of people they have been in contact with
2) if a person is unaware they are positive then a test would mean they can isolate and stop giving it to others
3) the new test that shows if you have already had the virus means you can return to or remain on the job
Coincidence that the country that performed the most test and trace (South Korea) had it under control quickest. Test test and then test some more.
UK is 6th in total number of tests performed and about 8th in total per head of population. Nearly 1,000 per million compared to USA about 320 per million. So not exactly the case that UK are far behind.
Surprised me that Australia is 4th in total tests performed (not per head). Very reassuring for us down under.
Edit - just noticed that data is about a week ago. Not sure if any numbers have changed relative to each other.
We need to test those medical staff that are off because they think they may have it. They self isolate as a precaution yet may not have the Covid 19 virus. They are therefore out of action when all medical staff are desperately required.
My police contact was one of the first to be tested. Tested the day after the "China connection" was realised. Discovered a day later that it wasn't the Covid 19 virus (was a different one). Hence her station and all the staff she had worked with could carry on working. She was back 4 days later.
These people should be the top priority for testing.
