A20-A28: Certain zoonotic bacterial diseases

A25: Rat-bite fevers

Rat-bite fevers include a group of similar illnesses which are typically transmitted to humans through bites or scratches from infected rodents, most commonly from rats. However, these conditions can also spread if a person consumes food or drink contaminated by the bacteria carried by rats. Following the initial bite or contact, a fever often develops within three to ten days, accompanied by symptoms such as headaches, muscle or joint aches, vomiting, and sometimes, a rash. As this fever progresses, complications can occur, affecting systems such as the heart, nervous system, and liver. Additionally, an ulcer or sore often forms at the site of the rat bite or scratch. Rat-bite fevers are generally curable, but early diagnosis and treatment are crucial.
