Why are four-year-old children prone to colds and bronchitis in autumn?

Babies are prone to catch cold, in addition to low resistance, but also because:

(1) cold virus antibody cannot remain in human body for a long time. Generally, the antibody of common cold virus can only last about 1 month, and the antibody of influenza virus can last about 8 ~ 12 months, so the immunity after a cold can generally last about 1 month, while the flu can last about 8 ~ 12 months.

(2) The immune function of antibody is specific. Although people who catch a cold can produce antibodies and gain immunity, this immunity is specific, only for the pathogen that causes this immunity, but not for other pathogens, so it is also called specific immunity.

(3) There are many kinds of viruses that can cause colds. According to research, more than 90% of colds are caused by viruses. At present, there are 12 kinds of viruses that can cause colds, including influenza virus, parainfluenza virus, rhinovirus, syncytial virus, coronavirus, adenovirus and enterovirus. The human body may be infected by another virus soon after being cured, so a person may have repeated colds in a short time.

Autumn and winter alternate, and the temperature is high and low, which is the season with frequent colds. At this time, some people often catch a cold with the change of climate. The last cold has not recovered, and the next cold will start again. I have an itchy throat all day, my whole body is tense, I feel cold and hot, and I am unconscious. Generally speaking, people with sufficient health and motivation are not easy to catch a cold, even if they catch a cold, they are lighter and cured faster. People with insufficient health motivation and low immunity are prone to catch a cold; After catching a cold, the symptoms are heavier than others, and the fever does not go back; A cold takes a long time and is difficult to cure. Frequent colds can easily lead to complications such as pneumonia, myocarditis and acute nephritis.

Therefore, when autumn and winter alternate, people who are prone to colds should pay more attention to preventing colds. There are many ways to prevent colds, but the key to prevent colds is to improve health motivation, enhance the local immune function of the whole body and respiratory tract trachea and bronchus, and resist various viruses or bacteria invading from the respiratory tract.

Beware of common diseases of children in autumn

Around the Mid-Autumn Festival, although the sun was blazing at noon, it was very cold in the morning and evening. If you don't add clothes to your child according to the climate characteristics, you may catch a cold. In terms of diet, we should always think about children's health, especially children with poor stomachs. If they eat indiscriminately, it is easy to induce gastrointestinal diseases.

The following are some common diseases prevention methods for parents' reference:

1, preventing colds and colds: This is the most common problem for children in autumn, especially around the Mid-Autumn Festival, when the autumn wind strikes, children with weak constitution are most likely to catch a cold sooner or later. Therefore, the way to prevent it is to pay attention to climate change, keep it hot and cold properly, especially when it is cold at night, and pay attention to covering the children with quilts. Add clothes when the wind is strong during the day, and the children are sweating outside. Pay attention to help him clean when he goes home. Don't take off your clothes and blow, or you will catch a cold. Besides preventive health care, children should also avoid contact with patients.

2. Beware of bronchitis: After catching a cold, many children are followed by bronchitis, and they are often out of breath. Some children even cough for two or three months. The main reason is that parents didn't pay attention to their children's initial cough. Just buy some medicine to eat, and the result is getting worse and worse, and the cough is worse. It can be seen that children should prevent bronchitis complications when they catch a cold, don't eat wind, don't eat cold things, rest at home, and run less outside, otherwise the child's cough will not be easy to get better. If they catch a cold again at night or come into contact with patients, they are prone to pneumonia, which is life-threatening.

3, pay attention to tonsillitis:/kloc-children under 0/0 have a higher incidence of tonsillitis, especially children in tonsil hypertrophy are more likely to suffer from tonsillitis, so once some children catch a cold and have a fever, their tonsils will be swollen, and some even have a high fever of more than 40 degrees Celsius. It is because some children usually take too many drugs and develop drug resistance that they get sick. If they don't get the doctor's permission, don't take medicine indiscriminately.

4. Pay attention to complications: While suffering from colds, bronchitis and tonsillitis, the most common complication is pneumonia. Many children are still ill, but they get pneumonia because of catching cold or touching patients, or because of tonsillitis. In addition to dyspnea, pneumonia also includes severe cough and high fever. If it is not treated in time, it will be life-threatening. To prevent this disease, we can't ignore the early onset, get sick early, and give children medicine if they are not smart.

5. Diarrhea: Diarrhea is also one of the common diseases in autumn. This is mainly because children eat indiscriminately and catch a cold easily. So pay attention to your child's daily diet, don't overeat, and pay attention to your child's abdomen. Don't catch cold.

Key points of children's autumn health care

First, strengthen nutrition autumn has come, the weather has turned cold, the interference of summer has ceased to exist, the body has gradually returned to a good state of operation, and appetite and digestive function have been automatically adjusted to the best level. This is a godsend opportunity to make up for the loss in summer. It is necessary to strengthen the nutrition supply and add "oil" to the growth of children. Meat, eggs and milk are indispensable, and fruits and vegetables should also be increased, so as to achieve a reasonable combination of staple food and non-staple food, vegetarian food, coarse and fine, dry and thin.

Second, timely pest control experts believe that the effect of pest control in autumn is the best. Judging from the life history of ascaris lumbricoides, although children can be infected with eggs all year round, they have the most opportunities in summer. If you suck your fingers, the eggs will enter the body, and after a period of evolution, they will eventually become insects and settle in the small intestine. It's autumn now. At this time, taking pesticides (such as enterotoxin) can be caught in the net, leaving no future trouble.

Third, prevent diarrhea. Babies are most prone to diarrhea in summer. After the autumn, the incidence of diarrhea showed a downward trend, but the heart of prevention must not be slack. Because a microorganism called rotavirus is ready to move, it often attacks children's digestive tract in September or 10 and causes diarrhea, which is called "autumn diarrhea". To this end, parents should help their children grasp the following points: First, block the entrance. Specific measures include paying attention to food hygiene, not eating cold food, boiling and disinfecting toys and utensils regularly, and washing nipples with warm water before feeding the baby. At the same time, we should do a good job in environmental sanitation and eliminate flies and other carriers that spread viruses and germs. In addition, the sick children were immediately treated in isolation, and the excreta was handled well. Healthy children should avoid contact with sick children.
