While you may not have heard of this virus, it is a dangerous disease that can be transmitted from rodents to humans. Infection can occur when humans are directly exposed to or inhale rat urine, feces and/or saliva. The risk of contracting the disease increases when people and rats are sharing living space. Symptoms include headaches, fever, muscle aches, abdominal pain, fatigue and chills. Ultimately, the disease can be deadly.

Bubonic Plague

You probably remember hearing horror stories in history class about the toll the bubonic plague took on Europe during the Middle Ages. While it is much less common these days, it has not been totally eradicated and it is still possible to contract this deadly disease. It is most commonly spread by being bitten by an infected rat flea. A bite can result in a headache, fever and severely swollen lymph nodes.

Rat Bite Fever

This is another potentially deadly disease that humans can contract if they eat food that has been contaminated by rats. Symptoms tend to occur 3-10 days after the initial ingestion of bad food. Infected humans will experience fever, vomiting, muscle pains and rashes that can be fatal.


Salmonellosis is also caused by ingesting contaminated food. While it isn’t considered a deadly disease, it can cause severe and uncomfortable symptoms that include fever and diarrhea.
