This is one of the most important lessons from the reported case of the 22-year-old woman.
Her illness was described as progressing from an apparently familiar symptom into a critical condition in only a matter of days.

A sore throat primarily affects the throat, so major changes in a person's mental state or overall physical condition can be particularly concerning.
Confusion, extreme weakness, faintness, severe dizziness, or unusual difficulty staying awake can indicate that an illness is affecting more than one localized area.
Severe infections can sometimes lead to sepsis, a dangerous response to infection that requires urgent treatment.
Not every episode of fatigue indicates a medical emergency, of course. Feeling tired is common when the body is fighting an infection.
The key is severity and context.
