Viral Fever - Signs & Treatment

Viral fever is a very common ailment today, it is caused by a virus leading to either low-grade fever causing common cold or flu. Whereas the high-grade fever (103 F) causes dengue. The viral fever symptoms are nasal and chest congestion, sore throat, runny nose, loss of appetite, etc. As antibiotics don't work for viral fever, there are a lot of home remedies like; consuming lime and honey, tulsi leaves, moringa leaves, etc. Maintaining good personal hygiene will also keep the viral fever at bay. Children and the elderly are more susceptible to viral fever, they should take care and adhere to preventive measures so as to avoid complications such as seizures, dehydration, infection of the blood, etc.


 What is Viral Fever?

Viral fever is caused by a viral infection arising due to the transmission of tiny germs from one individual to another. Once you contract a viral condition, the immune system of your body starts fighting the infection. This raises the body temperature from the normal range of around 98.6°F to anything up to 103°F. Any increase in the normal body temperature above 1°F is called a fever.

While low-grade fever is caused by ordinary viral infections, like the common cold and flu, a high-grade fever of up to 103°F can be caused by certain critical viruses such as the Dengue Virus. As opposed to bacterial infections, viral infections can’t be treated using antibiotics. These infections run their course, ranging from several days to a week or even longer, and doctors can prescribe medicines for the fever to manage the symptoms. Here’s everything to know about viral fever. 

What Causes a Viral Fever?

Viral fever results from getting infected by a host of viral infections such as parainfluenza virus infection, Severe Acute Respiratory Syndrome (SARS), norovirus and rotavirus infection of the gastrointestinal tract, measles, smallpox, chickenpox and chikungunya viral infection and hepatical (inflammation of the liver) viral infections, like Hepatitis A, B, etc. These viruses are spread by ticks, mosquitoes and by coming in contact with an infected person’s body fluids.

1. Viral Fever Causes in Babies

Babies and children face a higher risk of viral infections as their immunity is low. They are especially susceptible to infections such as common cold, bronchiolitis, tonsillitis, mumps, chickenpox, influenza and ear infections.

2. Causes of Viral Fever in Men

According to medical research, the intensity and prevalence of viral infections are generally higher in males. However, viral infections in men can be treated by antiviral medications, with lesser risks of adverse reactions. Common infections in men include those of the respiratory system, gastrointestinal system, nervous system, reproductive system, etc.

3. Viral Fever Causes in Women

As per research, as compared to males, women show a comparatively better and more robust immune response to viral infections. But when it comes to antiviral drugs and vaccines, women can face adverse reactions because of their higher immune (antibody) response. A stronger immune response also makes women susceptible to autoimmune diseases such as thyroid, rheumatoid arthritis etc. The common viral infections in women are the same as those among men.

4. Viral Fever Causes in the Elderly

People with advanced age are more prone to viral infections because of comparatively weaker immune systems. 

 What are Viral Fever’s Symptoms?

The foremost symptom of a viral infection is fever. The body’s increase in temperature allows your body to destroy the protein in the germs and thus prevent them from multiplying. Additionally, one might even experience several other viral fever symptoms like:
