8 Symptoms of the Flu

1. Fever

A fever transpires when the body’s immune system is set off by pyrogens, which are fever-producing substances. One such pyrogen is the Flu virus.

The development of this symptom is oftentimes a clear sign that something is off in the body, and that pyrogen activity is occurring within it. With the flu, one of the most common symptoms is an abrupt fever that generally lasts 3-4 days.

Body temperatures exceeding 100.4 F are an especially clear indicator that the Flu virus may be present and taking hold. Unfortunately, medium and high-grade body temperatures are not uncommon, ranging from 102 F to 104 F. When the body’s internal thermostat reaches this level, it is usually best to pay a visit to the physician’s office or nearest emergency facility, especially if the patient is a child, an elder, and/or a person with other health complications.
