Haverhill Fever, also known as Rat-Bite Fever or Streptobacillary Fever, is a rare bacterial infection caused by the ingestion of contaminated food or water, or from being bitten by an infected rodent. The symptoms of the infection can range from flu-like symptoms such as muscle aches, joint pain, and fever, to more severe symptoms such as swelling and redness around the wound site or rash. Other synonyms for Haverhill Fever include Streptobacillosis or Spirillosis. It is important to seek medical attention if any symptoms arise, especially if a person has had recent contact with rodents or consumed contaminated food or water. Treatment usually involves antibiotics and supportive care.
