What are the symptoms of fever after being scratched by a cat?

Fever refers to an elevated body temperature. In general, fever following a cat scratch may be a symptom of local infection, subcutaneous tissue infection, lymphangitis, lymphadenitis, or systemic infection. The details are as follows:

1. Local infection: After a cat scratch, the wound may become infected, presenting with redness, swelling, pain, and pus discharge, often accompanied by fever. These are common signs of wound infection. Under medical guidance, medications such as sodium laoxycarbapenem for injection or aztreonam for injection may be used to relieve symptoms.

2. Subcutaneous tissue infection: If the infection spreads to surrounding subcutaneous tissues, it may cause pain, swelling, and systemic symptoms such as fever and fatigue. Patients may take levofloxacin tablets, amoxicillin granules, or azithromycin tablets as directed by a physician to alleviate symptoms.

3. Lymphangitis: If the infection extends to the lymphatic vessels, patients may notice red streaks along the skin due to swollen lymphatics, usually accompanied by fever and localized discomfort. Under medical supervision, treatments may include potassium penicillin for injection, cefadroxil tablets, or ampicillin capsules to relieve symptoms.

4. Lymphadenitis: A cat scratch can lead to infection in nearby lymph nodes, causing lymph node swelling, pain, and fever. Under a doctor's guidance, medications such as roxithromycin tablets, minocycline hydrochloride capsules, or cephalexin dry suspension may be used to manage symptoms.

5. Systemic infection: In rare and severe cases, a cat scratch may lead to systemic infection, manifesting with generalized symptoms such as high fever, chills, headache, nausea, vomiting, and overall weakness. This is uncommon but requires immediate medical attention if these symptoms occur.

If any of the above symptoms persist or worsen, patients should seek prompt medical care to prevent disease progression.
