Current Fever

What Causes Fever?

Fever can have various causes, ranging in severity from 'troubling' to 'life-threatening'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

  • see your health summarized and in detail
  • learn what you should be doing right now
  • have a doctor review your case (optional)

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose 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 "fever" as a symptom.  Here are eight possibilities:
  • Sepsis
  • Infectious Mononucleosis
  • Myocarditis
  • Pneumonia
  • Gallbladder Disease
  • Gastroenteritis
  • West Nile Virus
  • Cold Or Flu

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:
current very sore throat
rotten egg burps
having non-problematic gallstones
recent onset diarrhea
discontinued non-human estrogen use
recent onset fatigue
possible enlarged liver
frequent unexplained vomiting
major recent weight loss
frequent episodes of diarrhea
recent onset vomiting
having foamy urine
... and more than 70 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of fever:
Cause Probability Status
West Nile Virus 93% Confirm
Gastroenteritis 17% Unlikely
Pneumonia 13% Unlikely
Infectious Mononucleosis 0% Ruled out
Myocarditis 0% Ruled out
Gallbladder Disease 0% Ruled out
Sepsis 0% Ruled out
Cold Or Flu 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 Current Fever:
Do you currently have a fever? If you do, try to rate your average temperature.
Possible responses:
→ Don't know
→ No
→ Mild fever, 99-100°F (37.2-37.8°C)
→ Moderate fever, 100.1-103°F (37.8-39.4°C)
→ High fever, usually over 103°F (39.4°C)
Based on your response to this question, which may indicate not having a fever, having a slight fever, having a moderate fever or having a high fever, The Analyst™ will consider possibilities such as:
Infectious Mononucleosis - Mono

A low grade fever occurs at first, and then rises to above 100°F after the third or fourth day.

Pneumonia

The common symptoms of pneumonia include fever.
