Alter-Lo found the expected level of viral mutation in fresh samples taken 15 years after the stored samples they had tested positive.

High level and sustained increases in viral load are frequently related to the development of drug resistance and/or viral mutations, and often dictate changes in ART.

It is possible, but not proven, that nutritional inadequacies in humans also may aid some viral mutation, the researchers said, urging scientists to look into this possibility.

John Barth wonders in his pages how many of the plagues were directly man-made and how many the result of viral or bacterial mutations, and comes to the reasonable conclusion that nobody can ever know.

He would have liked to have had the opportunity to study the latest viral mutation, but the risk was just too great.
