Meningitis can lead to high fever. Meningitis is an inflammatory response caused by pathogenic infections that invade the meninges of the central nervous system. Because it is also an infectious disease in itself, it can lead to fever, especially viral and bacterial infections, both of which can cause a significant increase in body temperature, often above 38-38.5°C. The duration of the patient’s fever is related to the promptness of treatment and the sensitivity to antibiotics and antiviral drugs. In the case of viral meningitis, after antiviral treatment, the body temperature can drop to essentially normal within 3-5 days. In the case of bacterial meningitis, the correct sensitive antibiotics need to be used, which will take effect in about 3 days and the temperature may drop to the normal range in about 1 week, while some patients may have recurrent fever with temperature fluctuations lasting 3 weeks or more.
