While a sustained high temperature is often the focus, fevers that fluctuate are a common occurrence. The medical term for **what is a fever coming and going called** depends on its specific pattern, with intermittent and relapsing being key classifications used by healthcare professionals.

According to the National Institutes of Health, a fever is an elevated body temperature of 100.4°F or higher. When a high temperature presents in a fluctuating pattern, it raises questions and points toward a specific group of conditions. Understanding **what is a fever that comes and goes** can help identify the root cause, which can range from a common infection to a more complex chronic illness.

Approximately 70% of fever cases are caused by common infections, but a temperature that comes and goes in waves can signal more than a typical illness. This phenomenon, known as intermittent fever, is when your body's temperature spikes before returning to normal for a period and then rising again.

While the body's normal temperature fluctuates throughout the day, different patterns of fever can indicate underlying health issues. Understanding **what is intermittent and relapsing fever** is key to proper diagnosis, as their distinct cycles point to different potential causes.

Approximately 1 in 5 people experience a recurrent fever at some point, indicating a complex biological process is at play. A fever is the body's natural defense against illness, but sometimes it returns even after seeming to resolve, leaving you to wonder: Why does my fever relapse? This phenomenon is not uncommon and points to deeper, unresolved issues within your system.

The average body temperature isn't a fixed 98.6°F (37°C), but a range that fluctuates throughout the day. When it rises significantly, the resulting fever can exhibit several distinct patterns over time. This guide will help you understand what is the temperature pattern for a fever and how it might indicate what's happening within your body.

According to research, many infectious diseases can cause fevers that come and go. Knowing **what is it called when a fever comes back?** can be crucial for understanding the body's warning signs and determining if further medical investigation is necessary. A fever that returns can be a sign that your body is fighting a long-term infection, inflammation, or an underlying medical condition.

Recurring fevers, where a person experiences multiple episodes of fever separated by periods of normal temperature, are medically referred to as periodic fever syndromes or systemic autoinflammatory diseases (SAIDs). These fevers are not caused by typical viral or bacterial infections and can indicate an underlying issue with the immune system.

The CDC reports that hundreds of cases of relapsing fever are reported in the U.S. each year. So, what is a relapsing fever called? This distinct recurrent illness, caused by bacterial infection, has specific forms and is named for its cyclical pattern of symptoms.

According to the Centers for Disease Control and Prevention (CDC), untreated soft tick-borne relapsing fever (STRF) can cause cycles of fever and symptom-free periods that repeat over several weeks. Understanding how long does a relapsing fever last is crucial for proper treatment and managing this unique infection.
