According to a study published in *JAMA Internal Medicine*, the average human body temperature is now closer to 97.9°F, debunking the long-held myth of a static 98.6°F baseline. This variability is crucial for understanding the difference between a normal temperature and what is a fever vs temperature, which is a purposeful, temporary increase orchestrated by the immune system.

According to infectious disease experts, a fever is your body’s way of signaling it’s fighting an infection. Yet, deciphering what causes a high fever but no other symptoms can be complex, involving everything from a normal response to an infection's early stage to more serious, systemic issues.

Fever, or pyrexia, is one of the most common medical signs, representing the body's natural defense mechanism against infection and other stressors. Understanding the specific medical term for fever like symptoms is crucial for differentiating between types of elevated body temperatures and their potential underlying causes.

According to numerous medical flashcards on Quizlet, a fever is a temporary increase in the body's core temperature that primarily signifies an active immune response to an infection. While not an illness in itself, a fever is a key symptom indicating that the body is fighting off a viral or bacterial invader.

Approximately 74% of fevers in hospitalized patients are caused by infections. Understanding the root cause often starts with medical terminology, and in medicine, the Greek root 'pyro-' signifies fever, heat, or fire.

According to research, a significant portion of all Fever of Unknown Origin (FUO) cases remain undiagnosed even after intensive investigation. If you're experiencing a fever with no apparent reason, it can be unsettling, pointing toward underlying issues beyond a simple infection and necessitating a methodical approach to diagnosis.

While both hyperthermia and pyrexia cause an elevated body temperature, only one is a regulated physiological response. This article breaks down the distinct medical origins and implications of **What's the difference between hyperthermia and pyrexia?** to help you understand these critical health distinctions.

An estimated one in five adults consult a doctor for a fever, yet many are unaware of the clinical term for this common symptom. So, what is the medical term for a fever? The scientific name is pyrexia, an essential indicator that your body's immune system is actively fighting off an infection or other health issue.

Approximately 50% of fever of unknown origin (FUO) cases remain undiagnosed despite extensive investigation. Understanding **what causes a high temperature without reason** involves exploring complex, non-obvious medical conditions beyond typical infections, from inflammatory issues to psychological stress.

The average adult body temperature is 98.6°F (37°C), but an increase above this range is a common sign of illness. A fever, known medically as pyrexia, is a regulated increase in the body's temperature set point, which is distinctly different from the condition of hyperthermia.
