What Is a Fever? (Symptoms, causes, treatment)

In this post, we will discuss the causes, symptoms, and treatment of fever.

We will also provide you with everything you need to know about this common health condition!

Let’s get started…

What Is a Fever?

Fever is a symptom, not an illness characterized by an abnormal increase in body temperature.

The average normal body temperature is 98.6°F (37°C) but may vary slightly from person to person.

A fever is usually considered to be present when the body temperature is 38°C (100.F°) or higher.

However, in some cases, a fever may be present even when the body temperature is only slightly elevated above 37°C (98.F°).

What are the five types of fever?

Here are five types of fever:

  1. Intermittent Fever: This type of fever comes and goes. The body temperature will rise for a period of time, then return to normal.
  2. Remittent Fever: Remittent fever is similar to intermittent fever, but the body temperature does not return to normal between episodes.
  3. Continuous or Sustained Fever: As the name suggests, this type of fever is continuous. The body temperature remains elevated for an extended period of time.
  4. Hectic Fever: Hectic Fever is characterized by high body temperature spikes. The body temperature may rise and fall rapidly, resulting in a “fevered” or “hectic” appearance. They are often accompanied by chills, sweats, and general malaise.
  5. Relapsing Fever: This type of fever is characterized by periods of fever followed by periods of normal body temperature.

What can cause fever

There are many different things that can cause fever.

The most common cause of fever is infection such as the flu, bronchitis, and pneumonia.

Infections are caused by viruses, bacteria, or other organisms that invade the body.

Other causes of fever include:

  • Food poisoning
  • Allergies
  • Inflammatory diseases (such as arthritis and Crohn’s disease)
  • Certain types of cancer.
  • Kidney disease
  • Liver disease
  • Pregnancy
  • Certain medications (such as antibiotics, steroids, or certain cancer treatments)
  • Sunburn
  • Heat exhaustion
  • Blood clots

What are the symptoms of fever?

The main symptom of fever is an increased body temperature (above 100.4°).

Other symptoms may include:

In some cases, a fever may also cause a rash.

What is the most accurate thermometer for fever?

There are many different types of thermometers available on the market.

The most accurate type of thermometer for fever is the digital rectal thermometer.

This type of thermometer is inserted into the rectum (back passage) and provides a more accurate reading than other types of thermometers.

Other types of thermometers include:

  • Digital ear thermometers
  • Forehead strip thermometers
  • Digital oral thermometers
  • Axillary (underarm) mercury or digital thermometers

Can I have COVID-19 if I have a fever?

Fever is one of the most common symptoms of COVID-19.

But, it is important to remember that not everyone who has a fever will necessarily have COVID-19.

There are many other causes of fever, such as influenza (flu) or other respiratory infections.

However, if a person has a fever with a dry cough, loss of taste, or smell, they may have symptoms of COVID-19.

The Centers for Disease Control and Prevention (CDC) instructs people with these symptoms to get tested for COVID-19 as soon as possible.

Also, they should stay at home and self-isolate to prevent spreading the virus to others.

What is the treatment for fever?

The treatment for a fever depends on the underlying cause.

If the fever is caused by an infection, the goal of treatment is to fight the infection and reduce the fever.

This can be done with antibiotics (for bacterial infections) or antiviral medications (for viral infections).

Other treatments for fever include:

  • Over-the-counter (OTC) medications to reduce fever, such as acetaminophen or ibuprofen
  • Drinking plenty of fluids to stay hydrated
  • Resting and taking it easy
  • Applying a cool compress to the forehead or neck
  • Using a humidifier to add moisture to the air

What is the fastest way to cure a fever?

The fastest way to cure a fever is to take medication such as acetaminophen or ibuprofen.

You should also drink plenty of fluids and rest as much as possible.

If your fever does not go down after a few days, you should see a doctor.

Can I prevent fever?

There is no sure way to prevent fever.

However, you can reduce your risk of developing fever by:

  • Washing your hands regularly and thoroughly
  • Avoiding close contact with people who are sick
  • Avoiding touching your eyes, nose, or mouth
  • Disinfecting surfaces that may be contaminated
  • Getting vaccinated against diseases such as influenza (flu)

Can fever be dangerous?

Fever itself is not dangerous.

However, a high fever can be a sign of a serious infection, such as sepsis.

Sepsis is a life-threatening condition caused by the body’s response to an infection.

If left untreated, sepsis can lead to organ failure and death.

If you have a high fever, you should see a doctor as soon as possible.

What is the difference between fever and chills?

Fever and chills are two different symptoms.

Fever is an increase in body temperature, while chills are a feeling of coldness.

Chills often accompany a fever, but they can also be a symptom of other conditions, such as hypothermia.

If you have both fever and chills, it is important to see a doctor to determine the cause.

Can stress cause fever?

Stress can weaken the immune system, making you more susceptible to developing an infection.

While stress does not directly cause fever, it can indirectly lead to fever by weakening your body’s ability to fight off infections.

If you are feeling stressed, it is important to find healthy ways to cope, such as exercise, relaxation techniques, or talking to a therapist.

When to see a doctor

Most fevers will go away on their own and do not require medical treatment.

However, there are some cases where fever may be a sign of a more serious condition and requires medical attention.

You should see a doctor if:

  • Your fever is accompanied by severe headache, shortness of breath, stiff neck, chest pain, or rash.
  • You have a high fever (above 103°) that lasts more than three days.
  • You have a history of heart disease, lung disease, or other chronic medical conditions.
  • Your child has a fever and is under the age of six.
  • You are pregnant.
  • You have recently traveled to an area where there is a risk of contracting a viral infection (such as the Zika virus).

Final thoughts

Fever is a common symptom of many illnesses.

In most cases, it is not dangerous and will go away on its own.

However, there are some cases where fever may be a sign of a more serious condition.

If you have a fever, it is important to drink plenty of fluids and rest as much as possible.

If your fever does not go down after a few days, you should see a doctor.
