Frequency Of Unexplained Fevers

What Causes Unexplained Fever?

Unexplained fever can have various causes, ranging in severity from 'minor' to 'generally fatal'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose unexplained fever, we could:

  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "unexplained fever" as a symptom.  Here are eight of many possibilities (more below):
  • Epstein-Barr Virus
  • Crohn's Disease
  • Ulcerative Colitis
  • HIV/AIDS
  • Sarcoidosis
  • Ovarian Cysts
  • Cerebral Gland Dysfunction
  • Leukemia

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
occasional painful urge to defecate
unusual vaginal bleeding
multiple swollen cervical nodes
having trouble concentrating
moderate right iliac pain
occasional unexplained vomiting
elevated lymphocyte count
blood clotting problems
moderate unexplained weight loss
moderate abdominal pain
angry/hostile disposition
frequent painful inguinal nodes
... and more than 120 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of unexplained fever:
Cause Probability Status
Cerebral Gland Dysfunction 90% Confirm
Epstein-Barr Virus 27% Unlikely
Sarcoidosis 20% Unlikely
Ovarian Cysts 0% Ruled out
Leukemia 0% Ruled out
Ulcerative Colitis 0% Ruled out
HIV/AIDS 0% Ruled out
Crohn's Disease 0% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

In the Metabolic Symptoms section of the questionnaire, The Analyst™ will ask the following question about frequency of unexplained fevers:
How often do you get unexplained fevers?
Possible responses:
→ Never / rarely / don't know
→ Occasionally - one or two per year
→ Frequently - several/many per year
Based on your response to this question, which may indicate either occasional unexplained fevers or frequent unexplained fevers, The Analyst™ will consider possibilities such as:
Leukemia

Fevers can occur due to associated bacterial, viral, or fungal infections.

Lupus, SLE (Systemic Lupus Erythematosus)

A less common but more serious constitutional feature of SLE is persistent fever.

Malaria

Symptoms of malaria include fever and flu-like illness, including shaking chills, headache, muscle aches, and tiredness.

Ovarian Cysts

When an ovarian cyst becomes twisted or ruptures it can cause fever.

Ulcerative Colitis

In severe acute attacks there may be fever.
