This is a memo from the McHenry County Health Department:
This memo is to update McHenry County healthcare providers of an ongoing investigation of an outbreak of Salmonella Typhimurium with the same fingerprint of JPXX0.0146 by the McHenry County Department of Health (MCDH) in cooperation with Lake, Kane, and Cook counties as well as the Illinois Department of Public Health.
The outbreak is statewide with 87 confirmed cases identified from July 2012 to the present date. The counties most affected are McHenry (23), Kane (18), Cook (15), and Lake (14). Attached you will find an Epi-Curve by county. The outbreak is affecting all age groups with the age range, in McHenry County from 2 months to 68 years of age. Multiple leads on suspect food sources have been identified and are currently being followed up on. Further epidemiological data is being withheld at this time so as to not form a bias for the investigation.
MCDH is asking that all healthcare providers to collect stool specimens from any patients that present with symptoms that are suspect for Salmonella. Most persons infected with Salmonella develop diarrhea, fever, and abdominal cramps. The illness usually lasts 4 to 7 days, and most persons recover without treatment. However, in some persons, the diarrhea may be so severe that they require hospitalization.
Any lab reports received as presumptive positive for Salmonella should be reported to McHenry County Department of Health Communicable Disease Program as soon as possible for investigation by fax (815-334-1884) or by phone (815-334-4500).
