Different fever patterns observed in Plasmodium infections. Various patterns of measured patient temperatures have been observed, some of which may be indicative of a particular medical diagnosis: * Continuous fever, where temperature remains above normal throughout the day and does not fluctuate more than in 24 hours (e.g. in bacterial pneumonia, typhoid, infective endocarditis, tuberculosis, or typhus); * Intermittent fever, where the temperature elevation is present only for a certain period, later cycling back to normal (e.g., in malaria, leishmaniasis, pyemia, sepsis, or African trypanosomiasis); * Remittent fever, where the temperature remains above normal throughout the day and fluctuates more than in 24 hours (e.g., in infective endocarditis, or brucellosis) * Pel–Ebstein fever is a cyclic fever that is rarely seen in patients with Hodgkin's lymphoma. * Undulant fever, seen in brucellosis * Typhoid fever is an example of continuous fever and it shows a characteristic step-ladder pattern, a step-wise increase in temperature with a high plateau. Among the types of intermittent fever are ones specific to cases of malaria caused by different pathogens. These are: * Quotidian fever, with a 24-hour periodicity, typical of malaria caused by Plasmodium knowlesi (P. knowlesi); * Tertian fever, with a 48-hour periodicity, typical of later course malaria caused by P. falciparum, P. vivax, or P. ovale; * Quartan fever, with a 72-hour periodicity, typical of later course malaria caused by P. malariae. In addition, there is disagreement regarding whether a specific fever pattern is associated with Hodgkin's lymphoma—the Pel–Ebstein fever, with patients argued to present high temperature for one week, followed by low for the next week, and so on, where the generality of this pattern is debated. Persistent fever that cannot be explained after repeated routine clinical inquiries is called fever of unknown origin. A neutropenic fever, also called febrile neutropenia, is a fever in the absence of normal immune system function. Because of the lack of infection-fighting neutrophils, a bacterial infection can spread rapidly; this fever is, therefore, usually considered to require urgent medical attention. This kind of fever is more commonly seen in people receiving immune-suppressing chemotherapy than in apparently healthy people. Hyperpyrexia Hyperpyrexia is an extreme elevation of body temperature which, depending upon the source, is classified as a core body temperature greater than or equal to ; the range of hyperpyrexias include cases considered severe (≥ 40 °C) and extreme (≥ 42 °C). It differs from hyperthermia in that one's thermoregulatory system's set point for body temperature is set above normal, then heat is generated to achieve it. In contrast, hyperthermia involves body temperature rising above its set point due to outside factors. The high temperatures of hyperpyrexia are considered medical emergencies, as they may indicate a serious underlying condition or lead to severe morbidity (including permanent brain damage), or to death. A common cause of hyperpyrexia is an intracranial hemorrhage. Other causes in emergency room settings include sepsis, Kawasaki syndrome, neuroleptic malignant syndrome, drug overdose, serotonin syndrome, and thyroid storm.
