1.What is recurrent respiratory tract infection?
(1) For those aged 0-2 years, acute respiratory tract infection more than 7 times per year or lower respiratory tract infection more than 3 times per year.
(2) For those aged 3-5 years, acute respiratory tract infection more than 6 times per year or lower respiratory tract infection more than 2 times per year.
(3) For those aged 6-12 years, acute respiratory tract infection more than 5 times per year or lower respiratory tract infection more than 2 times per year.
2.What are the causes of recurrent respiratory tract infections?
(1) Low immune function: The body has a humoral immune function (various antibodies) and a cellular immune function to resist respiratory infections. Both children with low humoral immune function and low cellular immune function are prone to recurrent respiratory infections. However, cellular immune function is most common in children with respiratory infections only.
(2) Congenital malformations: especially infants and children with congenital heart disease, congenital stupidity, cleft lip and palate.
(3) Nutritional deficiency diseases: such as malnutrition, anemia, rickets, zinc deficiency, vitamin A deficiency, etc.
(3) Allergies: This is our most common cause of recurrent respiratory infections.
3.What are the manifestations of allergic children?
(1) Allergies damage the skin and mucous membranes, so they are mainly manifested in the skin and mucous membranes.
(2) Including eczema, urticaria, and sandy dermatitis.
(3) Eye rubbing, watery eyes, and even frequent blinking.
(4) Runny nose, sneezing, nose blockage.
4.What are the other manifestations of allergic children?
(1) Frequent eye rubbing, nose picking, runny nose, sneezing.
(2) There are blue circles under the eyes.
(3) Often wake up in the morning with a foul taste in the mouth.
(4) Coughing after running or laughing.
(5) Sweating easily at night when sleeping.
(6) Do not want to walk more and often need to be held.
5. Why are children with allergies prone to infections?
Allergy can increase the secretion of respiratory mucous membrane, and allergy can be divided into rapid-onset and delayed-onset allergic reactions. Sticky nasal discharge can easily make bacteria stick to the respiratory tract and increase the chance of infection.
6.What time do I send my child to kindergarten after he/she is sick?
Viral and bacterial infections often affect the immune system and cause a temporary suppression of immune system function. However, it is difficult to determine the length of the “temporary” period. If no attention is paid to protecting the child during this “temporary” period of immune deficiency, it is easy for the child to have another respiratory infection. The time to return to normal will be longer, and the next infection will be easier. Many parents tend to ignore this very important point, in the child’s respiratory infection just a few days to get better, will be rushed to group institutions, it is easy to lead to re-infection.
7.Can drinking more water prevent recurrent respiratory infections?
Drinking more water can reduce the chance of respiratory infections, because the most common respiratory infections are pharyngitis and tonsillitis, which are the result of bacteria multiplying and growing in the throat and tonsils, and drinking more water can flush the mucus and bacteria adhering to them and reduce the chance of infection.
8.Is dry stool easy to catch a cold?
According to scientists’ research, the human rectum has glands that can produce humoral immune factors, which can help prevent respiratory infections. When the stool is dry or there is a buildup of stool, the intestinal secretion of humoral factors will be reduced, which will make the child prone to respiratory infections.
9. Why do children with allergies tend to cough in the morning and evening?
It has to do with the location of the sinuses and the opening. The secretions from the maxillary sinus are not easily eliminated when one is upright, and at night the secretions from the maxillary sinus flow into the pharynx and trachea, causing a paroxysmal cough. The secretions from the frontal sinuses are not easily eliminated when one sleeps, and in the morning when one is upright, there is a discharge of accumulated secretions. That is why the cough is strong in the morning and evening. We call it “nasolaryngolaryngeal drip syndrome” when there is frequent backflow of secretions.
10.Why do children cough after running?
For children with postnasal drip syndrome, exercise can trigger the secretion of the mucous membrane of the respiratory tract, causing the secretion from the sinuses to flow into the throat and trachea, resulting in a reflex cough. It can also induce bronchospasm, which manifests as an allergic cough. A higher percentage of asthma has post-exercise asthma.
