What causes a viral fever?

A viral fever means an infection due to a virus. As you might be aware, a virus is a small infecting agent that not only infects but multiplies within the cells of your body. When fever comes, it’s a signal that your body is fighting with pathogens (bacteria or virus).

A lot of viruses exist that are found to be sensitive to shifts in temperatures. And when your body raises its temperature suddenly, it helps it less hospitable to viruses.

There are loads of ways when you get infected with a virus like:

Bodily fluids: Exchanging bodily fluids with anyone who has a viral infection is likely to infect you as well. Some examples of this kind of infection include HIV and hepatitis B.

Bites: There are some animals like insects that can carry virus with them. After they bite you, they transfer the virus they carry with them. Such viral infections are seen in rabies and dengue fever.

Ingestion: At times, fruits and drinks are contaminated with viruses. After you eat or drink them, you can get contaminated with an infection. This kind of viral infection caused due to ingestion includes enteroviruses and norovirus.

Inhalation: If someone infected with virus coughs or sneezes near you, there are chances that you also get infected. It happens after you breathe in droplets containing the virus. Such kind of viral infection that spreads through inhalation includes common cold and flu.


How A Viral Fever Diagnosed?

In most cases, viral and bacterial infections cause almost similar symptoms. When you have a viral fever, your doctor needs to first rule out the chances of a bacterial infection.

The best way to do this is by analyzing reports of your symptoms and medical history. There are also some tests available to detect if you have a bacterial infection.

For example, if you are suffering from a sore throat, your doctor may take a swab of your throat to test for any kind of bacterial infection.

Now, if the sample comes negative, it clearly means that you have a viral infection and not a bacterial infection.

The doctor can also go ahead by taking your blood sample or other body fluids to check for a number of markers that indicate you having a viral infection. This can be done by analyzing your white blood cells count.


How Viral Fevers Treated?

In the majority of cases, viral fevers do not require taking any sort of specific treatment. Please note that viral infections don’t respond to antibiotics unlike bacterial infections.

In order to manage a viral infection, the line of treatment is to help you get rid of symptoms. There are some common treatments methods like:
