CDC Investigates Possible Hantavirus Case in Illinois

The Illinois Department of Public Health (IDPH) is investigating a potential hantavirus case in Winnebago County, with the Centers for Disease Control and Prevention (CDC) conducting additional testing. The patient, who has not traveled internationally or had contact with cruise ship passengers, is believed to have contracted the North American strain of hantavirus through exposure to rodent droppings while cleaning a home. The CDC cautioned that test results could take up to 10 days, and the patient is under observation. The case is unrelated to the deadly outbreak on the MV Hondius cruise ship, where at least 11 people contracted hantavirus, including three fatalities. The North American strain is not spread person-to-person, unlike the Andes strain linked to the cruise ship outbreak. Health officials emphasized that the risk of contracting hantavirus in Illinois remains very low. Common symptoms include fever, muscle aches, stomach pain, and nausea, which can progress to severe respiratory complications. A millionaire Oregon doctor, Stephen Kornfeld, who took over as the cruise ship doctor after the initial physician fell ill, also tested positive for hantavirus. The Andes strain, which caused the cruise ship outbreak, is not present in the U.S. rodent population.
