What is the reason why the fever persists and what is the reason for the persistent fever

Fever is commonly known as fever. There are many causes of fever, the most common is infection, and some non-infectious factors can also cause elevated questions, such as after surgery, burns, cancer, drug fever, rheumatic fever, hyperthyroidism, dehydration, dermatitis, etc.

First of all, you have to know what the fever body temperature you are talking about, the normal body temperature of a person is about 36 or 37 degrees.

Low-grade fever (below 38), 1. It may be primary low-grade fever: it is a disorder of body temperature regulation caused by autonomic nervous system dysfunction, which can last for months or even years, and the range of body temperature fluctuations is small, mostly within degrees. 2. In view of the time you asked, it may be a low-grade fever in summer, which is more common in young children, due to the imperfection of the thermoregulatory center, and the fever will subside after the autumn coolness.

3. If the fever is often obvious in the afternoon, and is accompanied by cough, rust-colored sputum, chest pain, night sweats, fatigue, etc., it is very likely to be tuberculosis, please seek medical attention in time to control it.

High fever (above degree) is more common in infections (such as pneumonia, nephritis, etc., with obvious systemic symptoms), and the other cause may be caused by drugs.

Ultra-high fever (above 41 degrees), it is estimated that it is impossible. At this point the person is very uncomfortable, even severely dehydrated or unconscious, and if you can insist on it to continue, it is very dangerous. Basically, at this time, people are in the hospital.

Is the fever urgent? Urgency is more common in infection.

Are there any chills? And other symptoms: such as cough, chest pain, abdominal pain, nausea and vomiting, diarrhea, rash, bleeding, headache, muscle and joint pain, etc.?

cough and chest pain are often accompanied by respiratory infections; Abdominal pain, nausea and vomiting may be liver and gallbladder problems, or intestinal infection; Rashes are common in measles, chickenpox, rheumatic fever, connective tissue diseases (such as lupus erythematosus), drug fever, etc.; Hemorrhage can be seen in severe infections and some acute infectious diseases (such as epidemic hemorrhagic fever, viral hepatitis, etc.), and also in some blood diseases (such as acute leukemia, severe aplastic anemia, etc.); Joint swelling and pain are seen in rheumatic fever, connective tissue disease, gout, etc.

Hope it helps you and wish you good health

Fever is a sign of inflammation in the body.

A person's normal body temperature is about 36tone, if higher than it, is called fever. So why do some people have persistent fevers?

Here are the reasons to study. The causes of persistent fever have been sorted out in detail for you. Coxsackieviruses belong to the state (phylum), the ketoviridae, and the enterovirus group are relatively stable at room temperature.

When the ambient temperature rises, only the virus survives, which is highly tolerant to acidic environment, insensitive to antibiotics and chemical drugs, but sensitive to oxidants, and easily killed by 1% high nickel acidity, 1% hydrogen peroxide or chlorine-containing oxidants. Coxsackieviruses are divided into groups A and B. Group A mainly causes neuromuscular and systemic infections, and occurs aseptic meningitis, paralytic diseases, upper respiratory tract infections, and heropatrope angina, which mainly invade the heart, brain, liver and other organs, causing myocarditis, pericarditis, viral encephalitis, etc.

Coxsackievirus group B can be divided into 6 types by measuring antigens with neutralization test and complement fixation test (). In recent years, it has been reported that this infection is the most harmful to newborns and has the highest incidence. Strengthen health care during pregnancy and actively prevent all kinds of infectious diseases from pre-pregnancy to prenatal care

The items and contents of the premarital physical examination mainly include: serological examination (such as hepatitis B, Treponema pallidum HIV) and reproductive system examination (such as screening for cervicitis), general physical examination (such as blood pressure, electrocardiogram), and personal past medical history. Including staying away from smoke, alcohol, drugs, radiation, pesticide noise, volatile harmful gases and toxic and harmful heavy metals.

During pregnancy, during prenatal care, systematic screening for birth defects is required, including regular ultrasound screening, serum screening, chromosomal testing, and genetic disease counseling. Once there are abnormal results, it is necessary to clarify whether to terminate the pregnancy, the safety of the fetus in utero, whether there are sequelae after birth, whether it can be **, what is the prognosis, etc. Take practical measures to diagnose and treat it.

1. Clinical characteristics of infant health examination: acute unexplained fever in perinatal neonates. Upper respiratory tract infection or sepsis-like manifestations with myocardial injury.

There are clinical manifestations of infection, but the disease progresses rapidly and the condition is critical. Bacterial infections are not supported. 2. Epidemiological information:

In summer and autumn, neonatal disease is concentrated. Children whose mothers or nurses in the nursery have a recent history of infection such as fever, and children who have a fever similar to that in the nursery, who have onset of illness at the same time or sequentially.

Coxsackievirus belongs to the RNA virus class (phylum), small RNA viridae, enterovirus group is relatively stable at room temperature, when the ambient temperature increases to 50, only survives, the virus has a strong tolerance to acidic environment, is not sensitive to antibiotics and chemical drugs, but sensitive to oxidants, and is easy to be killed by 1% potassium permanganate, 1% hydrogen peroxide or chlorine-containing oxidants. According to the characteristics of damage to organs, coxsackievirus is divided into two groups: A and B, group A mainly causes neuromuscular and systemic infection, aseptic meningitis, paralytic disease, upper respiratory tract infection, herpangina, etc., group B mainly invades the heart, brain, liver and other organs, causing myocarditis, pericarditis, viral encephalitis, etc. The incidence is also the highest.

Strengthen health care during pregnancy and actively prevent and treat all kinds of infectious diseases. Prophylaxis should be carried out from preconception to prenatal time:

The items and contents of the premarital physical examination mainly include: serological examination (such as hepatitis B virus, Treponema pallidum HIV virus), reproductive system examination (such as screening for cervical inflammation), general physical examination (such as blood pressure, electrocardiogram), and asking about the family history of the disease.

Pregnant women should avoid harmful factors as much as possible, including smoke, alcohol, drugs, radiation, pesticide noise, volatile harmful gases, toxic and harmful heavy metals, etc. During pregnancy, in the process of prenatal care, systematic screening for birth defects is required, including regular ultrasound examinations, serological screening, chromosomal examinations, and genetic disease counseling.

Once there are abnormal results, it is necessary to clarify whether to terminate the pregnancy, the safety of the fetus in the womb, whether there are sequelae after birth, whether it is possible, what the prognosis is, etc. Take practical measures to diagnose and treat them.

1. Clinical characteristics of infant health search: acute onset of perinatal fever of unknown cause. Upper respiratory tract infection or sepsis-like manifestations with myocardial damage. Patients with clinical manifestations of infection, but rapid progression of disease and critical illness do not support bacterial infection.

2. Epidemiological data: concentrated onset of neonatal disease in summer and autumn. The mother or the medical staff in the nursery have a recent history of fever and other infections, and the child with fever similar to the upper respiratory tract infection in the nursery has the same onset or onset of illness at the same time.

1. Infectious diseases are caused by bacterial, viral, and protozoan infections, which are the most common causes. Such as colds, pneumonia, bronchitis, distemper, etc. 2. Non-infectious diseases such as heat stroke, tumors, immune diseases, such as lupus erythematosus, rheumatoid, etc.

Drugs are used to cool people when they are hyperthermic. Avoid overdosing and repeating the drug in a short period of time. Frequent loss of appetite, excessive sweating, and heavy consumption.

Try to eat as much as possible an easy-to-digest diet that is high in vitamins and other nutrients, including fresh vegetable juices, fruit juices, etc., to increase the body's antibodies. Appropriate use of sedatives, such as diazepam, phenobarbital, hibernation, etc. Take your temperature regularly and watch for changes.

The body temperature was measured once half an hour, 1 hour, and 2 hours after taking antipyretics or physical cooling, and once every 24 hours at other times, and the change in body temperature was recorded. When you have a high fever, you should pay attention to finding ** and in time**. If it is a fever caused by an infectious disease, the condition will improve and it will naturally recover after a sufficiently effective antimicrobial drug**.

Common sense should be used to judge the amount of clothing. If you're hot, take off too much clothing to let your body get hot. But if you shiver, you should dress first until you are not cold.

Pay special attention to small babies because they feel too hot and don't yet know to take off their clothes. In fact, dressing your child too much or putting your child in a very hot place can cause a fever. Replenish fluidsWhen you feel hot, your body sweats to dissipate heat.

But when you lose a lot of water, if you have a fever, your body closes the sweat glands, preventing further water loss. This makes it harder for you to deal with fever. The solution is to rehydrate.

Wet compresses help lower body temperature. Tottenham can reduce fever. But when the patient feels very hot, you should improve them in a different way.

If your body temperature rises above degrees, don't use warm compresses to avoid further elevations. If the cold compress reaches body temperature, change it until the temperature drops. Wipe the whole body with a sponge to evaporate, it will also have a cooling effect.

Adjust the room temperature to create a ward atmosphere as much as possible, which is conducive to the recovery of patients. German doctors usually advise against letting the room temperature go too high and advise not to exceed Celsius. At the same time, the room should be moderately ventilated to facilitate recovery, but no ventilation equipment should be used.

Keep the light soft and let the patient relax. During the fever, you don't need to agonize about all the food (just drink juice) until the fever subsides. Some doctors think it's better to eat something because fever burns calories.

To put it simply, the choice is still yours, and you can eat what you want.

Nowadays, many people lack exercise, the body's immune system is usually relatively poor, and there are often some headaches and brain fever, and sometimes the fever does not go away, so what is the reason for the fever that does not go away.

1.First of all, analyze the causes of fever: most fever is caused by infection, and viruses are the most common, such as cold, flu, measles, infantile rash, epidemic costodenitis, etc., followed by bacterial infections, such as tonsillitis, crimson fever, epidemic meningitis, etc., parasitic infections also have fever, such as malaria, kala-azar, etc., but relatively rare; Non-infectious fever includes medium-centered, dehydrated, leukemia, tumor, trauma or after surgery; There are also some diseases with heat dissipation disorders, such as generalized dermatitis of ichthyoses and sweat gland deficiency.

Of course, sometimes it's not easy to tell the difference.

2.Secondly, if the fever is caused by the epidemic** caused by the virus, then under normal circumstances, common cold medicine or antipyretic medicine has no effect on the patient.

3.Finally, be cautious about the use of antipyretic antipyretics: low-grade fever or moderate fever generally do not use antipyretics, because premature antipyretic will also affect the establishment of immune function, and drug antipyretics often cause adverse reactions such as sweating and collapse.

When you have a high fever, you should also take medicine carefully, control it to the minimum dose that can achieve cooling, do not take it continuously, and children under half a year old should be more cautious.

Precautions. Most of the time, it is necessary to strengthen the individual's physique because of the cold and fever caused by the lack of human immunity.
