Viral Fever: Causes, Symptoms, Diagnosis, and Treatment

A viral fever is caused by an underlying viral infection that your body is fighting off. While the common cold and influenza are two of the most common viral, severe viral infections like norovirus and dengue can cause high-grade fevers.

If you are experiencing a high fever along with symptoms including cough, nausea, fatigue, and severe body aches, consider getting a medical assessment — nearly all viral infections are contagious.

What Causes Viral Fever

There are many ways to get exposed to viral infections:

  1. Inhalation (Airborne transmission):

    If someone with a viral infection sneezes or coughs near you, the micro droplets can remain suspended in the air, and you might inhale them. The flu and common cold are commonly transmitted this way.

  2. Ingestion (Direct contact transmission):

    You can get viral fever or infection after consuming food and drinks contaminated by viruses. Examples of this type are Hepatitis A, norovirus, and enteroviruses.

  3. Bites (Indirect contact transmission):

    Insects and animals can carry viruses. Their bites may cause infections like dengue fever and rabies.

  4. Bodily fluids (Direct contact transmission):

    The exchange of bodily fluids with someone with a viral infection can pass on the illness. Examples include Hepatitis B and HIV.

Also, these are the common viruses contributing to viral fever.

  1. Influenza viruses:

    Viruses that cause the flu, leading to viral fever with high temperature, that resulted in 140,000 – 710,000 hospitalizations and 12,000 – 52,000 deaths annually between 2010 and 2020.

  2. Dengue virus:

    The virus that attacks blood cells, leading to dengue fever and sometimes hemorrhagic complications.

  3. Epstein-Barr virus (EBV):

    A member of the herpesvirus family that causes infectious mononucleosis, with symptoms including fever and swollen lymph nodes.

  4. Rhinoviruses:

    One of the most contagious viruses responsible for the common cold, is nasal congestion, and other cold-related symptoms, like fever.

The Symptoms and Warning Signs of Viral Fever

  • Headache and body aches:

    These are common in viral fever due to the body's immune response. However, see a doctor if the headache becomes severe.

  • Fatigue and weakness:

    A feeling of generalized tiredness during viral fever is common as your body fights the infection.

  • Cough and congestion:

    Some viruses irritate the respiratory tract, resulting in cough and nasal congestion. Seek medical care immediately if you experience difficulty breathing.

  • Nausea or vomiting:

    Viral fever may cause gastrointestinal symptoms like nausea or vomiting. Again, seek medical attention for severe symptoms, such as vomiting or diarrhea resulting in dehydration and dizziness.

  • Chills and sweating:

    Fever often leads to chills and shivering as the body's temperature regulation is disrupted, followed by sweating as the fever breaks.

FAQs

1) How do you know if an infection is bacterial or viral?

Differentiating between a bacterial and viral infection will require a healthcare professional's evaluation, and certain specific tests, like blood tests or cultures, may be needed for an accurate diagnosis.

2) What is the fastest way to cure viral fever?

There is no instant cure for viral fever. The best approach is to allow the body's immune system to fight off the virus while managing symptoms. However, in some cases, antipyretic and antiviral medications are recommended to reduce your fever.

3) Which fruit is good for fever?

Citrus fruits (oranges, lemons), apples, watermelon, and berries can be soothing during a fever. They provide hydration, vitamins, flavonoids, and antioxidants that support the immune system.

4) How long does viral fever last?

The duration of a viral fever varies depending on the type of virus and an individual's health. It can last for 3-5 days to a couple of weeks. Consult your doctor as soon as possible if it persists beyond this timeframe or worsens.

5) Does viral fever go away?

Yes, viral fevers typically resolve on their own within 3-5 days as the body's immune system fights the infection. However, it's essential to manage symptoms, stay hydrated, and get enough rest to support recovery. If the fever or any related symptoms persist or worsen, medical attention may be needed.
