Has there ever been a published experiment to take a viral "census" of a human subject's blood?
By a "census", I mean to identify every active virus in the subject's blood with some probability.
So, for example, we can imagine taking different samples of blood, diluting them, then taking the dilution and using it to innoculate a lawn of hemocytes. Presumably, different viruses would make different plaques, so they could be separated, isolated and identified. By doing different combinations of dilutions, one could I suppose make a table or curve that would show the probability of detection of a given virus based on its concentration in the blood. Thus, at the end of the experiment the researcher could state, "I have isolated all the viruses in the subject's blood having a concentration above X with a probability of Y." Obviously, this would require hundreds of samples and thousands of innoculations to achieve an accurate census.
Has anyone published a study like this?
