@disf5178 in answer to your questions. Based on current or near current data you can test positive from about 2 days to 60 days after contracting the virus. You will only test positive (excluding false positives) if you are currently infected and it shows in nasal or oral fluids. The false negative rate is unknown to people like us, they would have a rough idea but no reason to tell people. You will not test positive unless currently infected or some dead virus remains in your nasal passage. I do believe it's possible to test with 99% accuracy for both currently infected or have had the infection, but it's completely impractical. The type of testing to achieve this would be blood testing done to the standard of trying to find trace dna at a crime scene. Very expensive and time consuming . The time consuming part means it's next to useless in this situation but for study maybe doing this is worth while. No amount of testing can demonstrate exposure, because as far as is known some people can resist every type of virus.

@Borvo1 interesting ratio. Same as incarceration ratio ironically.

@disf5178 the number of tests is not relevant. If you have contained the virus with a possibility of elimination the number of tests required will become lower. In Australia's case we are going for elimination but not calling it that because we are not overly confident. New Zealand the same along with other Western Pacific countries.
