Health Risks Associated with Rodents

Rats

Rodents can cause many problems within a home, including contaminating food and creating a fire hazard by chewing through electrical wires. Although rare, rodents can also spread dangerous diseases that can make you and your family sick. Understanding the methods of transmission and making a plan to keep rodents out of your house can help keep your family protected.

Rodents carry many diseases that can be passed to humans, but luckily, most of them are fairly rare. These diseases are transmitted through either direct or indirect contact with rodents. Direct contact may include: touching or breathing in feces or urine, eating contaminated food, handling a carcass, or receiving a bite. Indirect diseases are transmitted by a vector like a flea, tick, or mite.

​Hantavirus
​Deer mice are the main carriers of hantavirus. People who spend time in rural or wooded areas like hiking trails, fields, and barns are more likely to come into contact with deer mice. Hantavirus symptoms may include fever, chills, fatigue, dizziness, nausea, and respiratory distress. Deer mice shed the virus in their urine, feces, and saliva, so proper clean up of infestations and handling of dead rodents is essential.

Lymphocytic choriomeningitis (LCM)
The house mouse is the main carrier of LCM and spreads it mainly through particles of urine and saliva that get into the air or come into direct contact with the eyes, mouth, or areas of broken skin. This includes ingesting food that has been contaminated with the virus. Symptoms of LCM are fever, nausea, headaches, muscle aches, and vomiting. Severe cases of lymphocytic choriomeningitis may lead to meningitis and encephalitis.

Plague
Plague was once responsible for killing millions of people around the world, but it is now very uncommon in most first world countries. Plague is an example of an indirect disease. It is carried by rodents, but usually transmitted by fleas who feed on their blood and then bite humans. Plague can be found in over 200 wild animals, but some of the most common carriers are rock squirrels, prairie dogs, wood rats, ground squirrels, and chipmunks. Symptoms of plague may include: fever, headache, chills, and abdominal pain. Cases of plague are very rare in Ontario, and most infected individuals acquire it through travel outside of the country.
