This email notification just dropped into my inbox from Eau Claire, Wisconsin:

Over the past 5 days, our health care facility in northwest Wisconsin,
USA, has seen 3 women hospitalized with E. coli O157 infection. All
presented with significant abdominal pain without fever and watery
diarrhea which in 2 progressed to bloody diarrhea. None of the 3 have
manifested any evidence of hemolytic-uremic syndrome. Both of the
women seen by the Infectious Diseases service stated that their diet
contains a lot of salads.

We would appreciate any reports of upswings in the number of cases of
this process in the upper Midwest USA or elsewhere.
