Fever of unknown origin
With excellent support and advanced technology, we are here to help you maintain good health.
Fever of unknown origin (FUO) is a condition where a person experiences a persistent high temperature of at least 101°F (38.3°C) for more than three weeks or recurrently without any identifiable cause after diagnostic testing. While the source of the fever may not initially be identified, diagnosis is a crucial first step toward proper treatment. Early diagnosis and treatment are essential for preventing any potential complications associated with FUO.
Types of Fever of Unknown Origin (FUO)
The FUO may be divided into four categories:
Classic – People who were previously healthy are affected by classic FUO. It is characterized as a three-week-long, inexplicable fever. Classic FUO may be brought on by an infection or neoplasms like leukaemia.
Immune-deficient – People with weakened immune systems are more susceptible to immune-deficient FUO. Chemotherapy treatment generally results in a weakened immune system.
HIV-associated – Fever can be brought on by HIV. A person with HIV is more prone to infections that might result in fevers.
Nosocomial – It appears that hospitalization causes a fever in those with nosocomial FUO. After being hospitalized for a condition other than fever, they start to experience the undiagnosed fever.
Causes of FUO
A doctor at Best Pediatric Hospital in Hyderabad can identify the etiology of FUO by classifying the condition. The following causes of FUO can all be put into one category:
- Infection
- Inflammation
- Malignancy like lymphoma, leukemia, pancreatic carcinoma etc.
- Hepatitis, hyperthyroidism, drug use or addiction, and other conditions
Several clinical tests are administered to a patient with an FUO to determine the FUO’s categorization. A disease that might otherwise go untreated may come to light after the FUO diagnosis.
Symptoms
FUO may be accompanied by other symptoms that might assist medical professionals in identifying the underlying reason. A fever typically manifests as:
- A temperature that is higher than 99.5°F (37.5°C) for children and adults or 100.4°F (38°C) for infants
- Sweating
- Chills
- Headaches
- Sinus congestion
- Body or joint pain
- Weakness
- Fatigue
- Sore throat
- Cough
- Skin rashes
How Is FUO Treated?
In up to 50% of instances, patients with FUO are released from the hospital without a definitive diagnosis. A lot of the time, FUO resolves itself in these situations. The course of care for a FUO depends on the underlying causes.
- Infections are usually treated with antibiotics.
- Antihistamines and Nonsteroidal Anti-inflammatory Medications (NSAIDs) may also be used to treat FUOs with no obvious underlying reasons.
- Antiviral medication is the primary form of treatment for individuals with HIV-related fevers. Any accompanying symptoms or any consequences will then be treated.
