Dear Lisa,

You never know when the "beginning" might have been your only clear shot at the illness. A child exposed to cold dry winds, suddenly comes down with a fever, thirst for cold drinks, fearful, and you see a clear Aconite case...waiting, as it moves out of Aconite...into who-knows-what, might be risky.

Jim Henson, of Sesame Street fame, had an annoying cold, thought he'd ride it out, wound up in the hospital, and as you probably know, died.
It wasn't the annoying cold he thought it was. So, you never really know what you're dealing with, until it may be too late.
