The number of cases of shigella in Rockford has exceeded 300.
The Winnebago County Health Department predicts the number will surge this summer.
Todd Kisner, with the Department’s Center for Health Protection, says the outbreak can’t be pinpointed to one place.
“Typically, when we see an outbreak of shigella, it’s usually confined to a daycare or a school," Kisner said. "But what we’re seeing with our community outbreak is – it’s going across the community."
Kisner says strict hygiene is the best defense against the bacteria.
