Viral fever and bacterial fever are generally not significantly different in terms of symptoms, and patients will both experience headache, muscle aches, and even fever. In terms of treatment, viral fever is easily recurring, and treatment with antibiotics is ineffective, and viral fever is generally self-limiting, with symptoms gradually relieved in 3-7 days under physical cooling such as drinking more warm water and warm baths. In contrast, if patients with bacterial fever are not treated with antibiotics, the symptoms of fever will not be relieved, and even the condition will gradually worsen, which can generally be distinguished by blood tests. Patients with viral fever have normal or low white blood cells and elevated lymphocytes, while other indicators are usually not significantly elevated. In contrast, bacterial fever can usually show a significant increase in white blood cells and C-reactive protein, and bacterial fever can easily cause bronchitis, pneumonia, and other respiratory or digestive infections. If a patient has a persistent fever of 38.5°C or higher, it is recommended to go to the hospital for prompt examination and treatment.
