Virginia Health Department officials are investigating the source of an E. coli outbreak that killed a 2-year-old girl in the southwest part of Virginia.
The 2-year-old was from Dryden, Virginia. She was brought to a hospital in Tennessee with her brother, also infected with E. coli. He survived and was later released.
At least 18 people have been infected over the past six weeks. Five of those are in western Virginia and 13 are in northeast Tennessee.
The Virginia Health Department says it has found similarities between the strains, but has not identified a common source.
