That is a phony picture. The PCR test detects a specific RNA. That RNA may be in a live wuhu virus or the dead remains of the wuhu virus.
The test does not get fooled by other RNA viruses such as the ones falsely suggested.
That said - no test is perfect so it is not 100% but it is much better and much more specific than the picture claims.
