Fever A person has a fever if the body temperature exceeds the normal range of 98 to 100 ° F (36 to 37 ° C). It is a common sign of infection.
As a person’s body temperature rises, they may feel cold until they stabilize and stop growing. People describe it as “chills.”
Eating, exercising, sleeping, time of day, and individual factors can also affect temperature.
When an infection appears, the immune system will attack to eliminate the cause. A high body temperature is a normal part of this reaction.
The fever usually goes away on its own. However, if the body temperature rises too much, it can be a symptom of a severe infection that requires medical treatment. In this case, a doctor may recommend medications to reduce it.

The Centers used for Disease Control, and Preclusion (CDC) urges people with these symptoms to stay home and stay away from others. The person should also cover their face if they are around other people.
In many cases, symptoms will improve without specialized treatment.

How to Take the Temperature
To take temperatures, most people now use a digital thermometer. Experts do not recommend using a glass thermometer because it can be dangerous. Some people wear a headband, but it can be less precise.
A person can put a thermometer under their arm or in their mouth.
To Use a Digital Device
Clean the mouthpiece with cold soapy water, then rinse it.
Switch on the device.
Place the tip under your tongue, towards the back of your mouth, and close your mouth. Or place it under your armpit and hold the device close to your body.
Wait for the indicator light to flash or for the thermometer to beep.
Read the Temperature
Lower than oral temperature, the average armpit temperature will be about 0.5 to 0.9 ° F (0.3 to 0.5 ° C).
If the understanding is 100.4 ° F (38 ° C) or higher, the person has a fever.
When Should I be Concerned
Doctors classify fevers according to their duration, comings and goings, and level.
The central body temperature varies from one to creature.
Most experts study a temperature of 100.4 ° F (38 ° C) to be already a fever; however, in children, it may be lower than 37.5 ° C (99.5 ° F).
Hyperpyrexia can appear when a person’s temperature exceeds 106 ° F (41.1 ° C).
Without treatment, it can lead to complications.

The Fever Can be:
acute if it lasts less than seven days
subacute lasts up to 14 days
chronic or persistent if it lasts longer than 14 days
Fevers that last for days or weeks without an explanation are called fevers of unknown origin.
A moderate fever is part of the immune system’s response to bacteria, viruses, and other pathogens. It helps the body fight infection.
However, it can be uncomfortable, and sometimes a high fever can lead to complications.
For this reason, doctors may sometimes recommend drugs titled antipyretics to lower a person’s temperature.
Examples include nonsteroidal anti-inflammatory drugs (NSAIDs), such as isobutyl phenyl propionic acid. Acetaminophen (Tylenol) can also reduce fever. A spirit can help, but it is not suitable for families and may not be ideal for some people taking blood thinners.
NSAIDs and Tylenol are available over the counter or online.
If a person sweats too much, they can become dehydrated. In this case, you will need to consume enough fluids to avoid complications.
How to Treat the Cause
Fever is a symptom, not an illness. A doctor may want to perform tests to identify the cause.
