Summary
Infectious diseases are a primary cause of fever of unexplained origin (FUO). This review examines infectious causes across various patient groups, including those with HIV and immunocompromised individuals.
Area of Science:
- Infectious Diseases
- Internal Medicine
- Clinical Diagnostics
Background:
- Fever of unexplained origin (FUO) presents a diagnostic challenge.
- Infectious etiologies are a leading cause of FUO across diverse patient populations.
Purpose of the Study:
- To review the spectrum of infectious diseases causing FUO.
- To analyze infectious causes in specific clinical contexts: classical FUO, HIV-infected patients, nosocomial FUO, and immunocompromised patients.
- To identify clinical features predictive of specific infectious diseases in FUO.
Main Methods:
- Literature review of infectious diseases associated with FUO.
- Categorization of FUO cases based on patient population (classical, HIV, healthcare-associated, immunocompromised).
- Analysis of clinical presentations and diagnostic clues for infectious etiologies.
Main Results:
- Infectious diseases are a significant contributor to FUO.
- The spectrum of infectious causes varies depending on the patient's clinical situation and immune status.
- Identifying key clinical features is crucial for diagnosing the underlying infectious disease.
Conclusions:
- A systematic approach is necessary to diagnose infectious causes of FUO.
- Understanding patient-specific factors aids in narrowing the differential diagnosis of infectious FUO.
- Clinical features are paramount in guiding the investigation of FUO.

01:25Types of Fever
Fever can be triggered by several factors, including infections, nervous system disorders, certain cancers, blood diseases like leukemia, embolism, thrombosis, heatstroke, dehydration, surgical trauma, crushing injuries, and allergic reactions.
Here are the different types of fever:
Here are the different types of fever:
01:25Increased Body Temperature
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
01:26Patterns of Fever
Before understanding the types and patterns of fever, it is essential to know its phases.
01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:22Methods of reducing fever
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.
