Introduction
Fever of 39°C persisting for one day without subsiding may be caused by conditions such as viral influenza, pneumonia, or rheumatic fever, and can be improved through physical methods or medication. Besides these relatively common causes, it could also result from conditions like purulent meningitis or leukemia, so thorough examinations should be conducted to identify the underlying cause and guide appropriate treatment. If the body is infected with a virus.
Fever of 39°C persisting for one day without subsiding may be caused by conditions such as viral influenza, pneumonia, or rheumatic fever. It can be improved through physical methods or medication. A detailed analysis is as follows:
1. Viral Influenza
If the body is infected with a virus, it invades the upper respiratory tract and multiplies locally, causing inflammatory changes. At the same time, toxins may stimulate the body's temperature regulation center via the bloodstream, leading to persistent fever, nasal congestion, runny nose, and other symptoms. Medications such as Shuanghuanglian oral liquid or antiviral oral liquid may be taken under medical guidance.
2. Pneumonia
When the body's resistance decreases, bacteria may invade the body and damage lung tissue, resulting in inflammatory changes such as congestion and edema. Main symptoms include persistent fever, cough, and yellow sputum. Under medical advice, medications such as cefixime capsules, amoxicillin capsules, or Pulike mixture may be taken to reduce inflammation and relieve cough.
3. Rheumatic Fever
The exact cause of rheumatic fever remains unclear, but it may result from infection with group A beta-hemolytic streptococcus, which triggers immune system dysfunction and leads the body to attack its own healthy tissues. Common symptoms include recurrent fever, sore throat, and swollen lymph nodes. Glucocorticoid medications such as dexamethasone tablets or prednisolone acetate tablets may be prescribed by a doctor for treatment.
Besides the above relatively common causes, persistent fever could also result from conditions such as purulent meningitis or leukemia. Appropriate diagnostic tests should be completed to identify the underlying cause and guide targeted treatment.
