To me a strain is identical to the whole of the quasispecies infecting a
patient, if one uses eg body fluid samples. If isolated from culture,
the strain is the isolate. A variant is a virus with a particular
genomic variation. This can be a single virus, or most of the viruses
present in an isolate or strain.
