When should a person definitely seek medical treatment?
Influenza without complications can best be managed by time and conservative treatment measures and does not require a visit to a clinician. Most people recover fully within seven to ten days. But if you are unable to drink fluids and are becoming dehydrated; have a persistent fever (102°F / 38.8°C, or higher) that does not respond to aspirin, acetaminophen, or ibuprofen; or experience difficulty breathing you should see a clinician.
