Viral Fever: Symptoms, Causes, Diagnosis, Treatment & Prevention Explained
In India, many people fall sick due to seasonal changes, especially during monsoon and winter. One of the most common illnesses during these times is viral fever. It affects people of all age groups and can spread quickly from one person to another. If not taken seriously, it may lead to complications. But don’t worry — with the right care and awareness, viral fever is usually manageable.
In this blog, we will explain everything you need to know about viral fever, including its symptoms, causes, diagnosis, treatment, and prevention.
What is Viral Fever?
Viral fever is not a specific illness. It is a term used to describe fever caused by a viral infection. When a virus enters your body, your immune system fights it, and this process often causes your body temperature to rise. This increase in temperature is known as fever.
Viral fever can range from low-grade (around 99°F) to high-grade (104°F or more), depending on the virus and the individual’s health.
Common Symptoms of Viral Fever
The symptoms of viral fever may vary from person to person. However, some symptoms are commonly seen in most cases:
- High body temperature (fever)
- Chills and shivering
- Body aches and muscle pain
- Headache
- Fatigue or weakness
- Loss of appetite
- Sore throat
- Runny nose or nasal congestion
- Cough
- Skin rashes (in some cases)
- Watery or red eyes
These symptoms usually last for 3 to 7 days. In most cases, viral fever is not serious, but if the fever persists for more than a week or gets worse, it is important to consult a doctor.
What Causes Viral Fever?
Viral fever is caused by a viral infection. There are many types of viruses that can cause fever. These viruses spread through:
- Airborne droplets – When an infected person sneezes or coughs, the virus spreads in the air.
- Close contact – Hugging, shaking hands, or being near an infected person.
- Contaminated food or water – Eating or drinking infected items can introduce viruses into the body.
- Mosquito bites – Some viruses, like dengue and chikungunya, are spread through mosquito bites.
Common viral infections that cause fever include:
- Influenza (flu)
- Dengue
- Chikungunya
- COVID-19
- Common cold
- Viral gastroenteritis (stomach flu)
- Measles and mumps (in children)
How is Viral Fever Diagnosed?
Doctors usually diagnose viral fever based on your symptoms and medical history. In mild cases, no specific tests are needed. However, if the fever is high or does not reduce after a few days, some tests may be recommended:
- Blood test (CBC) – To check white blood cell count and rule out bacterial infections.
- Dengue or Malaria test – If fever is high and lasts more than 3 days during the monsoon.
- COVID-19 test – Especially if symptoms include cough, sore throat, and shortness of breath.
- Urine test – To rule out urinary tract infection.
- Chest X-ray – If there’s a severe cough or suspected lung infection.
Timely diagnosis helps in managing the fever better and prevents complications.
Treatment for Viral Fever
There is no specific medicine to kill viruses that cause viral fever (except in a few cases). Most viral fevers go away on their own within a week. The treatment focuses on reducing the symptoms and helping the body fight the infection.
Common Treatment Methods:
Paracetamol or fever-reducing medicines – To bring down the temperature and reduce body aches.
Rest – Taking complete rest helps the body recover faster.
Stay hydrated – Drink plenty of water, juices, and ORS to avoid dehydration.
Light diet – Eat easily digestible food like khichdi, soup, or fruits.
Avoid self-medication – Don’t take antibiotics unless prescribed by a doctor.
In some cases, if the fever is due to dengue or chikungunya, hospitalization may be required.
Home Remedies for Relief
In addition to medicines, you can also try some home remedies for comfort:
- Cold compress – Use a wet cloth on the forehead to reduce a high fever.
- Tulsi (basil) tea – Known for its antiviral properties.
- Ginger and honey – Helps soothe a sore throat.
- Steam inhalation – Useful for nasal congestion.
Remember, these are only supportive measures. If symptoms worsen, see a doctor immediately.
When to See a Doctor?
You should visit a doctor if:
- Fever is above 102°F and not reducing.
- The fever lasts more than 3 days.
- You have rashes, breathing trouble, or chest pain.
- Vomiting, dizziness, or severe weakness is present.
- The child is extremely sleepy or irritable.
Early medical attention can prevent serious complications.
How to Prevent Viral Fever?
Prevention is always better than a cure. You can follow these simple steps to protect yourself and your family from viral infections:
