The chills and shivering described by the patient should be clinically considered more likely to be a bacterial infection. Common features of these diseases are high fever, chills, and shivering. Common disorders may include acute pyelonephritis, which is common in women in their reproductive years. There is pain in the lower back, along with frequent, urgent, and painful urination. If the urine routine is checked, there may be pus urine, while certain perinephric infections, renal abscesses, cellulitis of the kidney, and acute biliary tract infections can also cause infectious fever and the formation of systemic abscesses. Acute appendicitis, acute cholecystitis, and perforated 12-finger ulcers can also manifest as chills, high fever, chills, and shivering. There are also more serious colds, primary infections such as sepsis, systemic infections caused by Staphylococcus aureus, infections caused by Escherichia coli, such as biliary tract infections, urinary tract infections, and intra-abdominal infections after abdominal surgery, which can also cause chills and fever. Certain anaerobic infections, where the body is infected with anaerobic bacteria, can also cause chills and high fever, while specific diseases like typhoid, paratyphoid, acute bacterial endocarditis, liver abscesses, and inflammation of the portal vein can generally cause fever all over the body. Most viral infections, such as coxsackievirus infection and type 1B viral infection, can also cause chills and fever. If a patient has chills, chills, high fever, or shivering, it usually indicates that the patient has an infection and needs to be treated promptly in a hospital to identify the cause.
