Third Human Case of Hantavirus in Illinois
State health department offers guidance on how to avoid infection
SPRINGFIELD – The Illinois Department of Public Health (IDPH) is reporting the third case of hantavirus pulmonary syndrome, a rodent-spread disease, in Illinois. Final confirmatory testing from the Centers for Disease Control and Prevention (CDC) will be available next week. The state’s first case, reported in 1996, was a northwestern Illinois man who died from the disease. The second case, in 2005, was a Kankakee County resident who had worked in a greenhouse. The third case is an Iroquois County resident who first exhibited symptoms in late April of this year and was hospitalized in May with fever and shortness of breath. The patient has been discharged from the hospital and is recovering. The individual became ill after cleaning out a structure where rodents were seen.
Hantavirus pulmonary syndrome is a rare but serious respiratory infection that can be life threatening according to the Centers for Disease Control and Prevention (CDC). Humans can become infected by inhaling dust contaminated by droppings, urine or saliva from infected rodents. Hantavirus can also be transmitted through bites from infected rodents or from direct contact with rodent excretions, followed by touching the mouth or nose prior to hand washing. It takes approximately two weeks for symptoms to appear, but can range from a few days to six weeks. Symptoms can be similar to some types of pneumonia or common respiratory viruses like influenza, and may include fever, headache, muscle aches, nausea and vomiting.
The deer mouse is the most common rodent carrier of hantavirus. Rodents that carry hantavirus are generally found in rural and sometimes suburban areas. The common house mouse does not spread the virus. The deer mouse is tan or brown in color with white hair on the underbelly, while the typical house mouse is gray.
Since 1993, 587 cases of hantavirus have been reported in more than half the states in the U.S. Cases often occur in the spring after spring-cleaning in homes and businesses.
To minimize the risk of hantavirus citizens should:
