Several county health departments and the state Department for Public Health are investigating a small outbreak of salmonella in three Central Kentucky counties.
At least six people who live within 5 miles of Berea have contracted the bacterial illness. Cases have been reported in Rockcastle, Madison and Garrard counties.
It's not unusual to see this many cases of salmonella sickness in a year, but it is unusual to see them at once, said Christie Green, spokeswoman for the Madison County Health Department. "To have them in this cluster is what's gotten our attention," she said.
The source of the outbreak wasn't known Tuesday, although investigators think it is a common source.
Symptoms include diarrhea, fever, nausea and abdominal cramps. The illness usually lasts four to seven days, and most people recover without treatment. The elderly, infants and those with impaired immune systems are more likely to have severe symptoms.
