Tamiflu has shown up in rivers and sewage treatment plants.  What this could mean is we've added one more "stressor" to the influenza virus.  Influenza reacts to such stressors by mutating.  The researchers who reported on the study say "The recent increase in OP (the active metabolite of tamiflu) resistance in influenza A virus (H1N1; commonlly called “swine flu”) has raised questions about the widespread use of Tamiflu in seasonal epidemics and the potential ecotoxicologic risk associated with its use in the event of a pandemic."

This quote is scary for two reasons: first, the H1N1 is already resistant to tmiflu, meaning it has mutated due to exposure, and second, the concern regarding possible toxic effects of tamiflu in the envirnment.  Perhaps we should think about supporting the immune system with Andrographis and vitamin D rather than waging chemical warfare against the influenza virus?
