What Is a High Fever?
Fever is the body’s natural response to infection or illness, generally defined as a body temperature above 100.4°F (38°C). While mild fevers can be harmless, a high fever (103°F/39.4°C or higher) often indicates a more severe condition requiring urgent medical care. If untreated, prolonged or extreme fevers can cause dehydration, seizures, or organ stress, especially in children and older adults. Recognizing when a fever is dangerous is critical to getting the right care at the right time.
Types of Fever
High fevers can vary based on severity, duration, and cause:
By Duration:
Acute Fever:
Appears suddenly, often caused by infections such as influenza or bacterial illness.
Persistent/Chronic Fever:
Lasts over a week, possibly linked to inflammatory conditions or ongoing infections.
Intermittent Fever:
Temperature rises and falls, sometimes seen with malaria or autoimmune conditions.

99°F–100.3°F, typically linked to mild infections.
High Fever:
103°F or higher, requiring urgent medical evaluation.
Hyperpyrexia:
106°F or higher, a critical emergency with risk of organ failure.
High Fever? Skip Urgent Care — Go to the ER
Mild fevers can often be treated at urgent care, but severe or persistent fevers belong in the ER. At Altus Emergency Center in Lake Jackson, we use advanced diagnostic tools such as blood work, imaging, and cultures to identify the cause quickly. High fever may be a symptom of sepsis, meningitis, pneumonia, or heat stroke—all of which demand immediate intervention. In our ER, patients have rapid access to IV fluids, antibiotics, antivirals, and emergency monitoring—treatments not available at urgent care.
When to Seek Emergency Care for High Fever
Come to our Lake Jackson ER immediately if you or your loved one has:
- Fever of 103°F (39.4°C) or higher in adults, or 100.4°F (38°C) or higher in infants under 3 months.
- Fever with stiff neck, confusion, or severe headache (possible meningitis).
- Seizures or fainting during a fever episode.
- Persistent cough, chest pain, or shortness of breath with fever.
- Rapidly spreading rash along with elevated temperature.

Risks of Delaying Treatment
Delaying care for a high fever can allow serious conditions to worsen. Meningitis, pneumonia, sepsis, or encephalitis can progress rapidly, leading to organ failure, brain damage, or even death if not treated early. Infants, elderly adults, and individuals with weakened immune systems are at higher risk of complications. Seeking prompt ER care at Altus Emergency Centers in Lake Jackson ensures that life-threatening illnesses are diagnosed and treated before they escalate.
