Fever – 7 Common Causes, Associated Symptoms & Treatment


A fever is an increase in body temperature that happens as a result of sickness and lasts only a few days. A fever is a sign that something strange is happening inside your body.

A fever in an adult can be uncomfortable, but it isn’t usually a cause for concern unless it hits 103 degrees Fahrenheit (39.4 degrees Celsius) or higher. A slight rise in temperature in infants and toddlers could indicate the presence of a serious infection.

People may feel cold when their body temperature rises until it reaches a peak and stops rising. This is referred to as “chills” by those who have experienced it.

Temperature is influenced by a variety of things, including what you eat, exercise, sleep, the time of day, and your own preferences.

When an infection occurs, the immune system goes on the offensive to try to eliminate the source of the sickness. This response is known to cause a rise in body temperature.

Fevers subside after a few days. A fever can be treated with a variety of over-the-counter drugs, but it’s sometimes preferable to leave it alone. Fever appears to play an important part in your body’s ability to fight against a variety of infections.

Common Causes of Fever

The hypothalamus, also known as your body’s thermostat changes the set point of your regular body temperature upward, resulting in fever.

You may become chilled and add layers of clothes or wrap yourself in a blanket, or you may shiver to generate more body heat, resulting in a raised body temperature.

The normal body temperature fluctuates throughout the day, with a lower temperature in the morning and a greater temperature later in the afternoon and evening. Although most people consider 98.6 degrees Fahrenheit (37 degrees Celsius) to be normal, your body temperature can range by a degree or more — from around 97 degrees Fahrenheit (36.1 degrees Celsius) to 99 degrees Fahrenheit (37.2 degrees Celsius) and still be considered normal.

Fever or a rise in body temperature can be caused by a variety of factors including:

1. A virus

2. A bacterial infection

3. Heat exhaustion

4. Certain inflammatory conditions such as rheumatoid arthritis — inflammation of the lining of your joints (synovium)

5. A malignant tumor

6. Some medications, such as antibiotics and drugs used to treat high blood pressure or seizures

7. Some immunizations, such as diphtheria, tetanus and acellular pertussis, covid or pneumococcal vaccine

Symptoms Accompanying Fever

People who have a fever may also experience the following symptoms:

1. Shivering and feeling cold when nobody else does

2. Sweating

3. Having a low appetite or loss of appetite

4. Showing signs of dehydration including sunken eyes, reduced salivation, reduced tears.

5. Having increased sensitivity to pain

6. Lack of energy and feeling sleepy

7. Having  difficulty concentrating

If a baby has a fever, they may also;

1. Feel hot to the touch

2. Have flushed cheeks

3. Be sweaty or clammy

4. With a higher fever, there may also be irritability, loss of consciousness, and seizures.

How to Check Body Temperature

There are various varieties of thermometers available for taking body temperature, including oral, rectal, ear (tympanic), and forehead (temporal artery) thermometers.

The most accurate way to assess core body temperature is with an oral or rectal thermometer. Although practical, ear or forehead thermometers provide less precise temperature readings.

The steps to checking body temperature include;

1. Clean the thermometer using cold water and soap, and then rinse it.

2. Place the tip under the tongue, toward the back of the mouth, and close the mouth or place it under the armpit and hold the device close to the body.

3. Wait for about 1minute for the device to record the body temperature

4. Read the recorded temperature.

Treatment of Fever

The immune system responds to bacteria, viruses, and other pathogens with moderate fever. It aids the body’s ability to resist illness.

It can, however, be inconvenient, and a high temperature can also result in consequences.

As a result, antipyretic drugs may be prescribed by doctors to lower a person’s fever.

Examples of antipyretics include;

1. Nonsteroidal anti-inflammatory drugs (NSAIDs) e.g ibuprofen

2. Acetaminophen (Tylenol)

Regular hand washing and other sanitary measures can help reduce the risk of infections that usually cause fever.
