Viral Fever Symptoms - Causes, Diagnosis and Treatment

What is Viral Fever?

A body temperature of about 98.6°F (37°C) is normal, and anything higher than 100.4°F is considered a fever. When you have the flu or cold, your body temperature spikes due to viral infection.

Moreover, people nowadays have resorted to self-medication instead of reaching out to healthcare providers, which increases the chance of multiple complications when they suffer from viral fever.

What is the Indicator of Viral Fever?

A majority of us would have encountered some fever in our lifetime. But what is it exactly? Is it a disease?

Fever is nothing but your body’s immune response to disease-causing pathogens such as bacteria and viruses. Whenever your immune system detects the entering of such foreign bodies, it triggers an immune response that increases your body’s temperature.

In both adults and children, we check the temperature in the oral, rectum and tympanic membrane.

If the temperature in the rectum, ear or oral is higher than 100.4°F (38.0°C), it indicates a viral fever.

List of Viral Fever Symptoms

Viral fever may present with the following symptoms:

• Both joint and muscle aches
• Headache
• Fatigue
• Sore throat
• Runny nose
• An increase in body temperature
• Dehydration
• Frequent chills
• Redness of eyes
• Skin rashes
• Appetite loss

Even though these viral fever symptoms disappear in about 3 – 4 days, people should always see a doctor if they persist or worsen.

Viral Fever Symptoms in Kids

Viral fever in kids is quite common, especially during seasonal changes or when their immune systems are still developing. While most cases are mild and self-limiting, recognizing the symptoms early can help prevent complications and ensure proper care.

• High fever (typically between 100.4°F and 103°F)
• Chills and shivering
• Fatigue or unusual tiredness
• Sore throat or runny nose
• Cough

Viral Fever Duration

The viral fever duration totally depends on the various factors like the type of virus, the person’s age, and their immune response. But here is a general breakdown of the duration of viral fever in children and adults.

• In Adults: Viral fever in adults lasts 3 to 5 days, though some may resolve in as little as 1 day or extend up to 7 days in more persistent cases.

• In children: Viral fevers in children often last 5 to 7 days, and in some cases, especially with weaker immunity, they may stretch to 10 days

Causes of Viral Fever

The body's immune system responds with a fever when it encounters or fights foreign pathogens. Your body's immune system naturally gets the impulse to fight back certain harmful pathogens like viruses and bacteria that make their way into your body.

The body's temperature soars high when this behaviour takes place. Viruses are most commonly transmitted by:

• Air Droplets Inhalation : The air droplets of an infected person spread by coughing, talking or sneezing near you, without covering their face. When it is inhaled, it can result in an infection.
• Food indigestion : You are likely to contract an infection if you consume contaminated food items. Viruses infect foods, so you might get infected by them when you consume such foods.
• Mosquito Bites : Monsoon is the time when the mosquitoes breed on stagnant water and multiply, resulting in an outbreak of diseases like malaria and dengue. It is also possible to contract viral fevers from mosquito bites.
• Body Fluids Exchange : Infections such as viral fever, hepatitis B and HIV can be acquired from blood transfusions and from being pricked by an infected needle. They can also be sexually transmitted.

Types of Viral Fever

Based on the area it affects, viral fever can be classified under the following types:

1. Respiratory Viral Fever

When a virus affects your respiratory tract, usually its upper or lower part, it is a respiratory viral disease. Some common respiratory viral infections are:

• Flu
• Common cold
• Coryza
• Viral bronchitis
• Laryngitis
• Viruses
• Rhinovirus
• Adenovirus infection
• Para-influenza virus infection
• Respiratory syncytial virus infection
• Measles
• polio

The SARS-Cov-19 infection caused by a novel coronavirus, the viral infection currently ravaging the world, also comes under this category.

2. Viral Enteritis

This type of viral infection affects your digestive tract. Gastrointestinal viral fever is also known as Stomach Flu. It often leads to a health condition called Gastroenteritis.

The following are some common infections of gastrointestinal virus:

• Rotavirus infection
• Adenovirus infection
• Norovirus infection
• Astrovirus infection

3. Exanthematous Viral Fever

When viral infections affect the skin in addition to causing fever, such infections are termed Exanthematous viral infections. Some common Exanthematous infections include:

• Measles
• Chickenpox
• Rubella (German measles)
• Roseola

Such infections often cause visible skin eruptions and rashes that last for days before they subside and heal by scab formations. These infections mostly occur in children but are not limited only to them.

With timely vaccination, the bulk of such infections can be prevented.

4. Hemorrhagic Viral Fever  

Some viruses can cause life-threatening situations by bleeding manifestations, and such a family of viruses is named a hemorrhagic virus. They usually raise your body temperature to high levels.

This type of infection affects your blood vessels and platelets leads to internal bleeding. Some viral fevers that belong to this category are:

• Ebola
• Dengue
• Yellow fever

5. Neurologic Viral Fever  

A virus specifically infects the Central nervous system, is called a neurotropic virus and such viruses cause neurological infections.

Some common infections of such kind are:

• Encephalitis
• Meningitis
• HIV
• Rabies

Mostly, the virus enters your bloodstream and reaches the brain or spinal cord. The neurological viral diseases are further classified into acute and chronic viral infections.

How to Diagnose Viral Fever?

It is not easy to diagnose a viral fever by merely assessing its signs and symptoms, as plenty of reasons can trigger the fever in your body. Various diagnosis methods are required to conclude that you have a viral fever.

Most of the time, the symptoms of bacterial and viral infections seem similar. Hence, doctors usually try to rule out bacterial infections to diagnose viral infections.

Doctors do this by analysing your medical history and symptoms. They also take samples (blood, urine, sputum, etc.) from you and send them for tests, for instance, the blood test, urine test and swab test.

If no bacteria has been detected in the above samples, it may be concluded that the individual may be diagnosed with viral infection.

Doctors also conduct a test to confirm the presence of the virus by recommending tests such as rapid influenza diagnostic tests. Blood, sputum and urine tests are also conducted to confirm the presence of the virus in your body.

Viral Fever Treatments

The preliminary step in treating a viral fever is to concentrate on reducing the symptoms. In most cases, you may not require any treatment for viral fever as your body fights against the virus and recovers on its own.

However, if a person's condition doesn't normalise within 3-4 days, the person needs to be treated for viral fever.

Medicines for Viral Fever

Unlike bacterial infections, antibiotics do not affect viruses. However, you can take antibiotics to prevent secondary bacterial infections.

In some cases, doctors prescribe antiviral drugs for specific viral diseases to whom the diagnosis has been confirmed by lab tests. Antiviral therapy can be started in such cases. Viral fever can be managed with paracetamol and antihistamines.

Viral Fever Treatment at Home

During viral fever, you’ll be dehydrated as your body sweats more.

To replenish your body, you need to intake a lot of fluid. Apart from normal drinking water, you can intake:

• Fresh juice
• Broths
• Soups
• Decaffeinated tea
• Coconut water

For babies and toddlers, you can rely on specialised drinks with electrolytes, such as Pedialyte, which you can purchase at a local pharmacy.

Another thing that you need to keep in mind is to take a rest. Because viral fever is a sign that your body works hard to fight infections, in such cases, you do not want to strain your body any further.

Taking adequate rest and avoiding strenuous physical activity will be of great help.

You can also rely on the following food items that prove to be effective viral fever treatment at home:

• Coriander tea
• Honey and lime juice
• Tulsi leaves in hot water
• Ginger tea
• Rice starch

Viral Fever Home Remedies for Children

Fever is a common problem for children. Some home remedies can be relied upon when it comes to viral fever.

You can adhere to the traditional method of bringing down the fever using a wet sponge.

Simply dip a clean sponge or muslin cloth in lukewarm water (between 85-90°F) and put it on the baby’s forehead and underarms. Repeat this a couple of times during the day.

What to do During Viral Fever?

• If you have a viral fever, take your prescribed medications on time to reduce its symptoms.
• Take antiviral medicine prescribed for you, which you must take as directed.
• Give sufficient rest.
• Keep hydrated by drinking lots of water.
• Consume lighter, digestible meals.

Things to Avoid When You Have a Viral Fever

• Avoid googling for symptoms and self-medicating.
• Avoid taking medicines without precise and accurate knowledge.
• Do not share any personal items, such as towels, soap, or handkerchiefs, when you have a fever.

Complications Accompanied With Viral Fever  

When viral fever is left undiagnosed and untreated for a long time, and when the fever prolongs, it might lead you to suffer from:

• Dehydration
• Shock
• Hallucination
• Seizures
• Coma
• Respiratory dysfunction
• Multiple organ failure

Who is Likely to Develop a Viral Fever?

Viral fever can affect anybody, irrespective of their age. However, the chances of developing viral fever are higher in children and adults with a weak immune system. Viral fever is contagious, and doing the following can lead to viral fever:

• Close ties with infected individuals
• Sharing needles
• People with disease and ailments from beforehand
• People traveling to or from contaminated areas
• Sharing belongings with an already infected person

How Can You Prevent Viral Fever?

Viral fever is very common and spreads mostly during the rainy season. To prevent viral fever, people must follow certain preventative measures.

• Prioritize their respiratory hygiene and personal hygiene.
• Impart lessons about hand-washing for children.
• Keep your nose and mouth clean. Do not touch your eyes or mouth.
• It isn't a good idea to let rainwater stagnant outside for very long, as it may increase mosquito breeding areas.
• Seek professional medical support when needed.

Difference Between a Viral Fever and a Viral Infection

• Viral fever is not a disease itself; it is a symptom characterized by a raised body temperature (fever) caused by a viral infection.
• Viral Infection happens when a virus enters the human body, multiplies, and causes damage to the host's cells or tissues.

Facts about Viral Infection

• The fever virus lasts for some days, generally from 3 to 7 days, though a few can last longer. In a few cases, such as dengue fever, it could be there for up to 10 days or more.
• You may know what causes a viral infection, but you may not know: Do viral infections cause fever? The answer is Yes. Viral infections can cause fever since the human body's immune system increases the body temperature to fight off the infection.
• Symptoms of viral fever typically subside within some days with proper care, but a few individuals might experience lingering fatigue or other symptoms.
• For viral fever treatment, the doctor's preferred medicine for viral infection is antiviral medications such as acyclovir, oseltamivir, and valacyclovir.
• Viral infection symptoms include fever, sore throat, cough, body aches, fatigue, etc.
• Some signs of a viral infection may worsen or persist for many days and, in a few cases, for up to 10 days or longer. The symptoms of a viral infection depend on the specific virus and the person's health.
• Viral infection treatment concentrates on managing symptoms of viral infection and supporting the body's immune response, as many viral infections do not respond to antibiotics.
• Under treatment for viral infection, antibiotics are not generally used, as they are ineffective.
• Serious viral symptoms include high fever, serious body aches, continuous fatigue, difficulty in breathing, and, in a few cases, seizures or loss of consciousness.
• Viral fever prevention includes practising good hygiene, like regular handwashing, and avoiding close contact with sick people. The signs of viral infection become severe with unhygienic conditions.
