Most people’s normal body temperature is about 98.6 °F (37 °C). A temperature above this is considered a fever, typically a sign your body is fighting an infection caused by bacteria or viruses.

What is Viral Fever?
Viral fever results from a viral infection. Viruses range from common cold and flu viruses to more severe ones like dengue fever, which can cause higher fevers. A hallmark of many viral infections is the presence of fever.
Symptoms of Viral Fever
The temperature typically ranges from 99 °F to over 103 °F (39 °C), depending on the virus. Common symptoms include:
-
Shaking chills
-
Sweating
-
Dehydration
-
Headache
-
Muscle aches and pains
-
Weakness
-
Loss of appetite
Causes and Transmission
Viral fevers occur when viruses invade and multiply within your body’s cells. Increased body temperature helps inhibit viral replication.
Common transmission modes include:
-
Inhalation: Breathing in droplets from an infected person’s cough or sneeze (e.g., cold, flu).
-
Ingestion: Consuming contaminated food or drink (e.g., norovirus).
-
Insect bites: Bites from infected insects or animals (e.g., dengue, rabies).
Diagnosis
Distinguishing viral from bacterial infections can be challenging due to similar symptoms. Physicians consider symptoms, medical history, and may conduct lab tests such as throat swabs or blood tests to identify the cause and rule out bacterial infections.
Treatment
Most viral fevers resolve without specific antiviral treatment. Care focuses on relieving symptoms:
-
Resting adequately
-
Staying well-hydrated
-
Using antiviral medications when prescribed
-
Taking measures like warm baths to reduce fever
Unlike bacterial infections, antibiotics are ineffective against viruses.

When to See a Doctor
Seek medical care if:
-
Fever exceeds 103 °F (39 °C)
-
Infants under 3 months have a rectal temperature above 100.4 °F (38 °C)
-
You experience severe headache, difficulty breathing, chest or abdominal pain
-
Persistent vomiting, rash, stiff neck, confusion, or seizures occur
These symptoms may indicate serious illness requiring prompt medical evaluation.
Conclusion
Viral fever is a response to viral infections ranging from mild colds to severe illnesses like dengue.
While most viral fevers improve independently, high or persistent fevers and alarming symptoms necessitate medical attention.
Proper rest, hydration, and symptom management are key to recovery.
