The immune system of children is not yet mature and should be physiologically immune. They are generally less resistant to disease than adults and are susceptible to bacteria, viruses and other sources of infection, such as colds, diarrhea, tonsillitis, pneumonia and other diseases. Therefore, scoring the immunity of children and taking appropriate preventive measures will have an important impact on their health status. The Chinese Society of Preventive Medicine has researched and launched the “Children’s Health Immunity Self-check Table” with 10 items, and the scores of each item will be added up to obtain a total score, which can be used as a reference for medical professionals, child health care workers and parents concerned. Specific criteria are as follows: 1, cold, cough (1) a year does not occur 10 points (2) 1-2 times a year 5 points (3) more than 2 times a year 2.5 points 2, paranoia, anorexia (1) no 10 points (2) is 2.5 points 3, diarrhea, abdominal pain or gastroenteritis (1) a year does not occur 10 points (2) 1-2 times a year 5 points (3) more than 2 times a year 2.5 points 4, pharyngitis, tonsillitis, pneumonia or (1) does not occur in a year 10 points (2) 1-2 times a year 5 points (3) more than 2 times a year 2.5 points 5, whether the child is easy to sweat (1) No 10 points (2) Yes 2.5 points 6, whether the child is easy to skin infections or allergies (eczema, herpes, acne, food or drug allergies, etc.) (1) No 10 points (2) Yes 2.5 points 7, whether the child is too fat or thin (1) (1) No 10 points (2) Yes 2.5 points 8, whether the child is breastfeeding or premature (1) breastfeeding, not premature 10 points (2) short-term breastfeeding 5 points (3) non-breastfeeding or premature 2.5 points 9, whether the child uses antibiotics and other drugs (such as intravenous drip or oral anti-inflammatory drugs) (1) a year does not use 10 points (2) 1-2 times a year 5 points (3) more than 2 times a year 2.5 points 10, vaccination status (1) all immunization 10 points (2) partial immunization 2.5 points Total score assessment tips, bright card is divided into 4 levels: 90-100 points immunity is strong; green card. 80-89 points of general immunity, to take early preventive measures; yellow card. 60-79 points immunity is weak, to pay sufficient attention, please consult experts; orange card. <60 points very poor immunity, below the basic immune defense of children, there is a certain risk; red card.
