How can I tell if my child has a viral or bacterial infection? How do you think it should be judged?

It can be judged according to the specific situation of the child, if the child is like a high fever or high fever persistent, it proves that the child is a bacterial infection and needs antibacterial and anti-inflammatory, if the child has severe diarrhea and vomiting, it proves that the child is a viral infection and needs antiviral**; I think I should take my child to the hospital for a routine blood test and make a judgment.

If the child does not recover for a long time after the illness or has a fever, it must be a viral infection, and if the illness is not particularly severe, it is likely to be a bacterial infection.

If the child has a cold for a long time, then it is a viral infection, and if it is just a general cold, then it is a bacterial infection that can be judged from the time.

Through the baby's mental state and blood routine examination, you can preliminarily analyze whether the child has a viral infection or a bacterial infection.

Children are more susceptible to viruses due to their lack of physical immunity, so parents should also strengthen the care of their children in their lives. If the baby frequently has typical symptoms such as cold, fever, runny nose and other typical symptoms in his life, he should go to the hospital in time**, which can fundamentally prevent the problem.

Distinguish from the child's mental state.

If the baby has a cold, nasal congestion, runny nose, cough and other symptoms. Parents can tell by the color of their snot. If it is a runny nose, cough is white phlegm, generally considered to be a virus, if the nose is runny, cough is yellow phlegm, it may be bacteria, in life should also learn to observe the child's mental state, if there is a lack of energy and poor appetite, the baby's body is very likely to have been disturbed, must intervene in time to avoid affecting the normal development of the baby.

What to do after a cold.

Parents must stabilize their minds after finding that the baby has a cold, if the baby does not have a high fever that does not go away, parents do not need to worry too much, you can use warm water to wipe the baby's limbs, help the baby cool down quickly, return to normal, if the baby has a high fever does not go away, it should be paid attention to, go to the hospital to receive a doctor's diagnosis and treatment, of course, in life should also learn to pay attention to the baby's sleep state, after the baby falls asleep, we must ensure that the temperature is appropriate, and ventilate and open the windows in normal times, which can also help the baby stay away from the virus.

How to improve your child's resistance.

Every parent wants their children to be healthy, so they should also spend enough time in life to accompany their children's healthy growth, and do more outdoor sports with their children, which can help babies better replenish the calcium needed by the body, promote the healthy growth of babies, and keep children away from places with more parasites when communicating with children, so as to avoid causing colds.

It can be seen through the child's performance, as well as the blood test, as well as the ** process; If it is a viral infection, then the symptoms are relatively mild, the baby's mental state, appetite will not be greatly affected, but if it is a bacterial infection, the symptoms are more serious, the child shows high fever, loss of appetite or do not want to move, drowsiness and other symptoms.

If the baby is more lethargic, has a high fever, loss of appetite, it may be a bacterial infection, if the symptoms are mild, the state is similar to usual, it may be a viral infection; It can be seen from the baby's mental state, the baby's appetite, the baby's exercise, the baby's mouth and snot.

If you want to know whether the child has a viral infection or a bacterial infection, it is best to go to the hospital to draw blood for a test, and you can see whether it is a viral infection or a bacterial infection in the blood routine, if the white blood cells in the test sheet are relatively high, then it is a bacterial infection, and if the white blood cells are lower than normal, then it is a viral infection.

Bacterial infections are different from viral infections in the following ways: 1. **: The pathogens that cause infection are bacteria and viruses respectively; 2. Symptoms:

Bacterial infection may cause fever, chills, purulent discharge, etc.; Viral infections are mostly manifested by systemic symptoms such as fever, fatigue, and body aches. 3. Laboratory indicators: bacterial infections mostly have elevated white blood cells, procalcitonin, C-reactive protein, etc., and viral infections mostly have normal or decreased leukocytes, normal procalcitonin, and mildly elevated C-reactive protein; 4. **: Antibiotics are mostly used for bacterial infections**, and antiviral drugs are used more for viral infections**.

Bacterial infection and viral infection are systemic infectious diseases caused by two different pathogens, and the difference between the two can be distinguished by blood culture. If blood cultures are positive for bacteria, the patient is indicated; Some patients can also check for antigens and antibodies to the virus, and if the antigens and antibodies of the virus are positive, it means that the virus is infected.

The two can also be distinguished by a complete blood test. In patients with bacterial infection, the blood routine shows markedly elevated leukocytes and neutrophils; In patients with viral infection, white blood cells and neutrophils are basically normal or decreased, and some patients will have elevated lymphocytes. Therefore, bacterial infection and viral infection can be distinguished according to the patient's symptoms and auxiliary examinations.

The ** of the two is also different, and the main antibiotic for bacterial infection is **; Viral infections are mainly carried out by antiviral**.

There are still some differences between the blood routine of bacterial infections and viral infections. But some of the same places will also be confused. Let's first look at the blood routine of bacterial infections, which generally have white blood cells, and the total number will increase by more than 10,000.

Then its classification is mainly granulocytes, lymphocytes account for a minority, which can be accompanied by an increase in C-reactive protein. Most of the viral infections are not high in the total number of white blood cells, and the cell classification is mainly lymphatic and mononucleosis, but the blood items of viral infection should be noted, such as influenza, some herpes viruses, and some Epstein-Barr virus infections, which will increase their white blood cells. The classification of early granulocytes is also predominant, but its monocytes are elevated.

If it is accompanied by mouth ulcers, that is, hand, foot and mouth, herpes stomatitis, and oral ulcers, these viral infections will also have an increase in C-reactive protein, but the increase in C-reactive protein is relatively low compared to that of bacterial infections. Therefore, when it comes to the distinction between bacterial infection and viral infection, parents roughly grasp the following points. That is to say, the classification of bacterial infection and leukocytosis accounts for the majority, and the white blood cells of viral infection are not high, and lymph and mononucleus account for the majority in the classification, so you can know.

Bacterial infections are outside the cells of the human body, while viral infections are invaded into the cells of the human body, and viruses cannot survive outside the cells. Viral infection can be followed by secondary bacterial infection and is a precursor to bacterial infection. Many viral infections are not targeted with medications**, and there are more drugs for bacterial infections.

Viral infections are usually self-limited, and bacterial infections can be over a long course.

First, the symptoms are different. Patients with bacterial infections often have symptoms such as fever and chills, and the discharge is mostly purulent discharge, such as purulent nasal discharge and purulent sputum However, when infected by viruses, patients often have symptoms such as limb pain and weakness, and rarely have purulent discharge.

Clause. Second, the use of antibiotics is different. If antibiotics ** bacterial infection are used within 72 hours, clinical symptoms will improve markedly, and if antibiotic ** viral infection is used, ** will not be effective.

Clause. 3. There are differences in test results. Bacterial infections usually show an increase in the proportion of neutrophils in white blood cells and a marked increase in C-reactive protein, whereas viral infections usually show no significant changes in white blood cells and neutrophils and an increase in lymphocytes.

Bacterial infections are distinctly different from viral infections. Only when the condition is clear, can the appropriate ** method be chosen.

Nature of lesions: Bacteria and viruses can cause upper respiratory tract infection, but the lesions caused by bacteria are mainly suppurated, which can cause redness, swelling and pus spots in the tonsils. However, viral infections are generally non-purulent lesions, and can also cause redness and swelling of the tonsils, but pus spots generally do not appear;

Most of the fever and colds in children are caused by viral infection, which can almost occupy 80 90, and bacterial infections are only less than 10%, and there are also some bacterial infections. oneGenerally speaking, if the virus is infected, the child's poisoning is very light, although they have a cold, but their mental outlook is relatively good; If it is a bacterial infection, the symptoms of food poisoning throughout the child's body are relatively serious, and the mental substance level is usually not good, and all people are listless, and they will feel very tired and weak.

Look at the child's sputum: the virus ** infected the child with little sputum and cold sputum, no color, accompanied by a dry cough; Bacteria** cough up white foamy sputum, dry cough is stronger, very easy to cause new crown pneumonia, human body temperature is high and low, and the child is in poor spirit after fever. Look at the child's tonsils:

The tonsils of children with viral colds must not have concentrated fluid, showing a bright red color, and there may be blisters or follicles; Bacteria ** There may be purulent discharge on the upper side of the child's tonsils, which are well known in color and uneven. Children's fever and cold is a very troublesome thing for parents, but as long as you learn this basic knowledge and grasp some relevant professional skills, I firmly believe that children's fever and cold can be easily solved. Whether it is a virus, a cold or a bacterial outbreak, the general identification criteria are also listed in six ways, which are generally enough to identify.

In addition, children with fever and cold do not need to blindly take medicine, because each of the child's evolutionary trees is not sound, blindly following the trend of taking medicine is likely to cause serious harm, should follow the doctor's advice. In many cases, parents rush to take the patient to the hospital for medical treatment, and the pediatric outpatient doctor usually asks the patient to check a blood routine test or C-C reactive protein after the stethoscope, why is this? This is not for doctors to better charge more standards, but to establish whether it is a viral infection, a bacterial infection or a mixed feeling.

The prevalence of viral colds is relatively high, accounting for about 80-90% of respiratory infections, and most of them are rhinovirus, new coronavirus, parainfluenza virus, etc. The symptoms are mostly manifested in sneezing, cold runny nose, dry cough, a little milky white sputum, itchy throat, mental essence, etc., and the situation can be severe with high fever, chills, headaches, etc., generally around 7 days**. The prevalence of bacterial ** is relatively small, about 20-30%, and can occur directly or secondary to low immunity caused by viral colds.

The symptoms are more common than significant sore throat, cough with pale yellow pus-like sputum, weak mental parency, etc., and the fever is mostly medium and low fever, high fever is rare, and upset, etc., and the physical examination can show tonsil congestion.

This is best to go to the hospital for examination, in order to be able to understand whether it is a virus, or bacteria, viruses are generally prone to this fever and fever, bacteria are naturally more secretions, of course, the final diagnosis is subject to the doctor's diagnosis.

First of all, viruses and bacteria are completely different, the next thing we have to understand is the bacterial cold, the first way to distinguish is according to the patient's physical symptoms, the bacterial cold will be contagious, and will lead to an increase in the white blood cell count, the patient can be distinguished by symptoms.

The second way to distinguish is to go to the hospital for an examination, which is the best way to determine the risk of bacteria.

The third way to distinguish is to look at the cause of the patient's bacterial exposure, and whether there is a direct cause of the patient's recent exposure to bacteria.

The fourth distinguishing method is that bacteria have a lot of bacterial manifestations, so patients can judge by their own conditions after a cold.

Under normal circumstances, the main risk of the virus is fever, cough, runny nose, physical exhaustion, and the bacteria will have tonsil inflammation, difficulty swallowing, sore throat, nasal congestion, etc., usually we must pay attention to the baby to replenish more water, drink more warm water, measure the baby's body temperature at any time, if the baby has a serious cold, you can go to the hospital for treatment.

This needs to be determined according to the child's physical condition, you can go to the hospital for an examination, to determine what is the cause, and it can be well determined through a blood test.

There are two types of colds in children, the common cold and the epidemic. The epidemic is mainly caused by influenza A and B viruses, with acute onset and severe illness; The common cold is mainly caused by rhinovirus, coronavirus, parainfluenza virus, etc., and is complicated by bacterial or mycoplasma infection due to the weakening of the child's resistance during the course of the disease.

It is not difficult to find that a cold is caused by a virus, while a fever may be caused by a virus, bacteria or mycoplasma.

When the child has a fever, if the child is only runny nose, sneezing, fever, etc., and the spirit is good, most of them are common colds, drink more water, pay attention to rest, and if the fever exceeds it, ibuprofen or acetaminophen can be appropriately given to reduce fever**. When the child has a high fever at the beginning of the illness, no sneezing, runny nose, etc., and the fever is manifested as malaise, it is necessary to be highly vigilant against the possibility of epidemics, and it is recommended to consult a pediatrician in time to make a clear diagnosis.

In the first few days, the child will have a runny nose and sneezing, followed by a cough with phlegm, which is not easy to cough up, a recurrent fever, loss of appetite, scratching the ears, etc. At this time, it is necessary to be highly suspicious of bacterial infections, such as pneumonia, tonsillitis, otitis media, etc.

When a child has a cough, especially a dry cough, with no obvious fever and no nasal discharge, a high level of suspicion is required for mycoplasma infection.
