Here are some patterns of fever.

An Intermittent fever involves periodic occurrences of fever and normal or subnormal temperature.

Likewise, a remittent fever is characterized by more than two degrees of Fahrenheit temperature fluctuations between morning and evening that do not reach normal levels.

A constant or continuous fever is when the temperature remains high and fluctuates by less than 1.5 degrees Fahrenheit.

A Relapsing fever is characterized by recurrent episodes of fever where the body temperature normalizes for at least a day and relapses soon after.

An Inverse fever is when the body temperature peaks in the morning and decreases by evening.

A Lysis fever involves temperature fluctuation in a zig-zag pattern for a few days, sometimes up to a week, before returning to normal levels.

Similarly, a crisis fever occurs when the body temperature rapidly drops after prolonged high temperatures.

A crisis fever is categorized as true or false. In a true crisis, the patient's condition improves; in a false crisis, it does not.

Lastly, a fever of unknown origin lasts for weeks to months and has no apparent cause.
