Map of the states where deaths have occurred (CA is on the list):

Good Map of cases which I've also seen.

Don't see much of a connection with hot springs. FL, with the most cases has no hot springs
as does TX (almost none) with second most. Idaho &Oregon with hundreds of hot springs
between them have zero cases.
