According to the Centers for Disease Control, mice bites are dangerous if the mice are infected with a disease that is transmissible between rodents and humans. These diseases include but are not limited to hantavirus pulmonary syndrome, lassa fever, hemorrhagic fever with renal syndrome, lymphocytic chorio-meningitis, plague, rat-bite fever and tularemia.
According to the Internet Center for Wildlife Damage Management, mice that individuals encounter in outdoor situations are at higher risk of being infected with viruses, such as hantavirus. This elevated cause of concern arises from the higher chance of wild mice coming into contact with other wild animals that might carry inner-species transmissible diseases.
The Panhandle Health District 1 in Idaho suggests that individuals take certain precautions to protect themselves, their children and their pets from illnesses brought on a mouse bite. These suggestions include keeping pet food in sealed containers and keeping the grass near the house short so that wild mice do not hide in tall grass near doorways. The organization also advises that homeowners or renters do not leave human food out on countertops for extended time periods and to place storage piles, such as firewood piles, far away from entryways to avoid encouraging mice to nest near home entrances.
