Understanding Fever: A Symptom of Your Body's Defense System

What is a Fever?

A fever is a temporary elevation in body temperature, typically above 98.6°F (37°C). It is a common symptom of many illnesses and infections, and is usually a sign that your immune system is working to fight off an infection.

Causes of Fever

Fever can be caused by a variety of conditions, including:

• Viral infections, such as the flu or a cold
• Bacterial infections, such as strep throat or pneumonia
• Fungal infections, such as histoplasmosis
• Parasitic infections, such as malaria
• Certain medical conditions, such as heatstroke or inflammatory diseases
• Certain medications, such as antibiotics or vaccines

Symptoms of Fever

In addition to an elevated body temperature, fever can also cause other symptoms, such as:

• Chills and shivering
• Headache
• Muscle aches
• Fatigue
• Loss of appetite

When to Seek Medical Attention

Most fevers are not serious and can be treated at home with over-the-counter medications such as ibuprofen or acetaminophen. However, if you have a fever that is:

• Higher than 103°F (39.4°C)
• Lasts for more than three days
• Accompanied by other severe symptoms, such as confusion, rash, or difficulty breathing

You should seek medical attention immediately.

The goal of fever treatment is to reduce the body temperature and relieve symptoms. Treatment may include:

• Over-the-counter medications, such as ibuprofen or acetaminophen
• Prescription medications, such as antibiotics for bacterial infections
• Cooling measures, such as a cool bath or compress
• Rest and fluids
