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.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose fever, we could:
|West Nile Virus||21%||Unlikely|
|Cold Or Flu||1%||Ruled out|
|Infectious Mononucleosis||0%||Ruled out|
Do you currently have a fever? If you do, try to rate your average temperature.
Possible responses:→ Don't know
→ 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)
A low grade fever occurs at first, and then rises to above 100°F after the third or fourth day.
The common symptoms of pneumonia include fever.
