Even the governments seem to be ignoring this in their consideration of PCR results - the PCR doesn't mean the virus is still live.
There are NO tests out there that can determine if the virus is viable ('alive'), or to differentiate between viable and non viable virus particles. The labs and public health authorities understand this.
PCR replicates a piece of the virus's DNA many times, so that if it's present in a sample (swab, blood sample etc) the DNA can then be detected by traditional lab techniques.
It's debatable whether viruses are living organisms; most of science deems them not to be:
