Researchers discover cold virus can 'hit and hide'
...ter 14 days, the virus could no longer be found in samples
taken from the airways, but tell-tale traces of the virus's genetic material (viral RNA) were still found lying dormant in lung tissue over 100 days later. The team believes that this may also be the case in humans, and that long after the initial sy...
