A fever isn’t an illness. Rather, an atypical increase in body temperature
can be a symptom of an underlying medical problem, such as an infection.
Most people who feel feverish can recover at home. However, certain people
may need medical care at a local hospital. If you’re in need of
medical care in the San Jose area, the emergency care team at
Regional Medical Center of San Jose is available 24/7.
Which Temperature Range Indicates Fever?
The average normal body temperature is 98.6 degrees Fahrenheit. This can
fluctuate from person to person and it may be influenced by external factors.
If a person’s body temperature is above 99 or 99.5 degrees Fahrenheit,
this generally indicates fever. A high-grade fever is about 103 degrees
What Are the Causes of Fever?
The hypothalamus in the brain is responsible for regulating body temperature.
A fever occurs when the hypothalamus “moves” the normal body
temperature upward. In response, patients feel chilly and may shiver to
produce more body heat, which raises body temperature. The underlying
causes of fever can include viral or bacterial infections, heat exhaustion,
inflammatory conditions, malignant tumors, and even severe sunburn.
Are There Any Possible Complications?
A fever may result in dehydration, which is why it’s important to
drink plenty of fluids while ill. Sometimes, patients with high fevers
may suffer hallucinations. Children may sometimes experience febrile seizures,
or fever-induced seizures.
When Should Patients Go to a Hospital?
This depends on a number of factors, including the age of the patient and
the severity of the illness. Adults should go to a hospital for high-grade,
persistent, or worsening fevers, as well as fevers accompanied by other
severe symptoms. If a child suffers a febrile seizure, he or she should
be seen at a hospital promptly. The same applies to children under three
months with a
temperature of 100.4 degrees or higher, and children of any age with temperatures above 104 degrees.
