1. Hantavirus
Rats can transmit the hantavirus, but only specific types in North America — the rice rat and the cotton rat. The rats may carry the disease in their saliva, so it gets transmitted into the wound when they bite you. Hantaviruses include a family of illnesses spread primarily through the rodent population. If infected, a human can get pulmonary syndrome, a rare infection that can cause life-threatening heart and lung problems.2. Leptospirosis
Like the hantavirus, leptospirosis also travels from a rat's saliva into a bite; however, people catch it more often from drinking contaminated fresh water. Leptospirosis affects animals and humans, and it is a bacterial disease. The condition is often confused with other diseases as symptoms are not specific. Left untreated, leptospirosis can cause several life-threatening conditions. Medical professionals warn the illness can lead to kidney damage, liver failure, meningitis, respiratory distress, and potential death.3. Tetanus
Rat bites can evolve into serious infections, including tetanus. The condition affects the nervous system, causing muscle contractions, specifically in the neck and jaw muscles. If you haven't received a tetanus shot in recent years, you may consider getting one after a rat bat. Doctors stress there is no cure for tetanus, and the symptoms may be life-threatening or temporary.4. Rat-Bite Fever
Rats may carry a specific bacteria known to cause rat-bite fever (RBF). There are two forms of RBF: streptobacillary RBF and spirillary RBF. Streptobacillary bites will often heal quickly, but you may experience symptoms within three to ten days. The symptoms include:- Headache
- Joint and muscle pain
- Skin rash
- Vomiting
- Diarrhea
- Fever and chills
- Sore throat
- Ulcer at the wound
- Swelling of the lymph nodes
