5 children hospitalized, 14 others diagnosed with E. coli after visit to Lake Anna

Officials with the Virginia Department of Health said several people contracted a bacterial infection while visiting Lake Anna on and after Memorial Day weekend. And while tests show the concentration of E. coli were below a “public health level of concern,” no single cause of the outbreak has been identified.

The department said 25 probable and confirmed cases of the bacterial infection have been reported from visitors since it began investigating the issue on June 11. Only four of those cases involved residents of other states.
