swine flu & echinacea

I've been reading several articles about swine flu and many of them state to stop using echinacea and other immune boosting herbs if you get it. Use those for prevention, but switch to herbs that support the immune system after getting it. The reason was that people who had the flu, even died from it, died from an "immune response" or "cytokine storm triggered by your own immune system health." The article that came from was talking about the bird flu, but another article had the same information applied to swine flu.
