How is the fever caused?

There are many diseases that cause fever, which can be roughly divided into three categories. One is infectious diseases, including infections caused by eight pathogens such as viruses, bacteria, protozoa and rickettsia. Almost all infectious diseases can cause fever, such as colds, AIDS, malaria, meningitis and SARS. The second is the fever caused by tumor, especially in the late stage of tumor. Third, autoimmune diseases such as lupus erythematosus can also cause fever. You can refer to the above reasons for further investigation. What is a fever?

Fever refers to the abnormal increase of body temperature: that is, the anal probe is Fahrenheit 100 degrees or above 38 degrees Celsius, or the oral probe is Fahrenheit 99 degrees or above 37.5 degrees Celsius. Generally, the mercury probe shall prevail.

Axillary exploration is usually inaccurate.

In-ear probing is not completely standardized. Please refer to the instructions of individual brands for correct use.

What is a high fever?

Generally speaking, a high fever at Fahrenheit 103 degrees or 39.5 degrees Celsius is called anal exploration. Whether it is dangerous or not is another question.

Although a minor illness can cause a high fever, on the contrary, a serious illness can cause no fever, but for safety reasons, it is generally assumed that the high fever is more serious and the positive cause is found.

Why do you have a high fever?

There are many reasons for fever. The fever of ordinary people is usually caused by infection.

Infantile fever is generally not caused by teething. It is dangerous to assume that you have a fever without seeing a doctor!

Another common cause of infant fever is the reaction after vaccination. But it may also be caused by other infections. It is dangerous to assume that it must be a reaction after vaccination without seeing a doctor.

Generally speaking, observing Cai's behavior and other symptoms is more important than simply paying attention to his body temperature.

Is fever harmful?

A fever may be harmful or useful. We can't generalize.

The biggest function of fever is to give an alarm, which is also a part of human immune function.

The harm of fever lies in the cause of fever, not in temperature. Although children's fever is usually caused by infection, fever itself does not cause harm. But if a fever causes a fever and cramps, that's another matter.

Fever cramps are also common. About three percent of children between six months and six years old have fever and cramps. Fever spasm is familial and secondary. General fever and cramp for less than fifteen minutes will not hurt the brain. Cramps usually occur when the body temperature rises rapidly, not when there is a high fever. Fever plus cramp may also be the only early symptom of meningitis or encephalitis, or it may be a complication of gastroenteritis or other diseases. Be sure to see a doctor at once.

Under what circumstances does a fever indicate a serious illness? Generally speaking, children should see a doctor quickly if they have the following symptoms: lethargy, too easy to lose their temper, listlessness, constant crying, crying weakness, pale skin, rash, long drooling and so on. Be sure to see a doctor.

The baby less than six months old has a fever, so it is best to see a pediatrician as soon as possible. It's too dangerous to judge Cai yourself. Sometimes they get seriously ill and their body temperature drops, instead of having a fever.

How to deal with a fever?

The most important thing is whether there are other symptoms when the food is closed, which is more important than the temperature!

Drink more water when you have a fever. The second is to help the body dissipate heat: reduce clothes (not too little) and turn on the fan less (be careful when turning on the air conditioner).

You can take an appropriate amount of antipyretics. Never overdo it.

Wipe or bathe with warm water when you have a high fever. But be careful when taking a shower.

After seeing a doctor, you can use a fever plug. Never overdo it. Using an antipyretic plug before seeing a doctor is like turning off the alarm without knowing the reason-stupid! )

But I always don't ...

Never use excessive antipyretics to reduce fever. The effect of antipyretics is only to relieve the patient's pain, but it can't help the disease.

Children with fever should not use aspirin or proprietary Chinese medicines containing aspirin, especially chicken pox, cold or virus infection. Raynaud's syndrome may be fatal, but it can also damage the liver and brain-this is no small matter!

Don't spray yourself with fire wine. This will make the epidermis cool, but at the same time, the blood vessels in the epidermis contract, making it unable to dissipate heat, and internal burns are more dangerous.

Don't sweat with the quilt. Adults have an experience-they wake up with a cold and sweat, and they are all right. This traditional practice may be caused by this misunderstanding. In fact, it is the adult's own immune system that overcomes sweating, cooling and fever (causal epilepsy). In fact, it is wrong to use the method of "local sweating" for children with fever-danger!
