What Causes Recurring Fevers?
There are many reasons for repeated fever, mainly due to unresolved infections, which easily lead to recurrent fever. The causes of infection are diverse, commonly including bacterial and viral infections, or other chronic inflammations, which may all cause repeated fever. It is even more necessary to be vigilant about repeated fever caused by tumorous conditions.
1. Infection: Fever is often caused by infection, such as bacterial and viral infections. Symptoms can be alleviated through some physical cooling methods. It is important to identify the cause as soon as possible and treat it accordingly.
2. Viral Fever: There are many causes of fever caused by viral infections. Fever due to viral infections usually improves significantly within a week. However, fever caused by secondary bacterial infections can generally be detected through blood routine tests.
3. Concurrent Bacterial Infections: If fever persists or recurs repeatedly, it is most likely due to influenza, which is caused by viral infections. Initially, it is a viral infection, but later, it may develop into a complex infection involving bacterial infections.
4. Tumor-Related Fever: If repeated fever occurs without a clear cause, and there is no significant improvement after medication, along with significant short-term decline in physical condition or symptoms such as anorexia and gastrointestinal bleeding, one should be vigilant about tumor-related causes and undergo timely examinations.
