I just landed from a 10-hour flight from Istanbul to New York and I have a few moments to update my blog.   On the plane I read the interesting CDC study from Scotland on the prevalence of “Secondary Cases” (person-to-person transmission from a primary E. coli O157:H7 infection).  The study found that secondary cases constituted 246/2,026 (12%) of the symptomatic cases (11% of all cases) on average in a given outbreak.

Over the last two decades, we have seen dozens of confirmed secondary cases and many that were likely.  Here are a few E. coli Outbreaks that included secondary cases:

• AgVenture Farms Petting Zoo E. coli O157:H7 Outbreak Litigation – Florida
• CCC Alternative Learning Daycare E. coli Outbreak – Texas
• ConAgra Ground Beef E. coli Outbreak – Nationwide
