Some parents have some general knowledge of chickenpox and can recognize it as chickenpox, but most parents still do not understand this disease, and even some parents, seeing the itching of the child, give topical application of Wuji cream, dermatitis and other hormone-containing creams, which is not correct, although chickenpox can itch, but it is not like This is definitely a contraindication to the application of hormonal creams. The two diseases are caused by the varicella-herpes zoster virus, which is an acute respiratory infection that occurs in children, mostly in school-age children, and is highly contagious, mainly through droplets and direct contact, the patient is contagious from the day before the rash to the rash crust. It can be easily contracted by adults, mainly high school and college students, and even women of childbearing age, and it can have a negative impact on the fetus in pregnant women. The symptoms of chickenpox in adults are more severe than those of chickenpox in children, and the chances of serious complications are higher in adults than in children. The disease is usually acquired only once in a lifetime, and after healing, you are immune for life, but there is still the possibility of getting shingles. The most important thing is that you have to be aware of the fact that your baby has already had the chickenpox vaccine, but you still have chickenpox. First of all, it is clear that vaccination is only a form of artificial active immunity, until the preventive effect, its characteristic is slow onset and long duration, the vaccine only plays a preventive role, so that the chances of developing the disease to the minimum, but it is not equal to the vaccination will not get the disease, this is a wrong understanding. In addition, there is a possibility that the baby has been infected with the chickenpox virus before the vaccination, but is still in the incubation period and does not show symptoms; or has been vaccinated, but has not yet produced antibodies, and has not had time to form an immune protective barrier before being infected with the chickenpox virus. Most children with chickenpox have relatively mild symptoms and signs, and many do not have obvious prodromal symptoms such as fever, sore throat, cough, and general malaise. The main clinical features of chickenpox are as follows: 1. the rash is polymorphic, at first papules, surrounded by a red halo, gradually become papules, blisters, rupture crust, after healing does not leave scars; 2. the rash appears in batches, so there are polymorphic skin before now, commonly known as “four generations together”; 3. centripetal distribution, that is, the rash is mainly distributed in the head and face, the trunk position, the limbs are relatively small. The rash is mainly distributed on the head and trunk, the extremities are relatively few, some children may have oral mucosa involvement; 4, itching, most children have obvious itching, sometimes scratching, serious cases are complicated by bacterial infection; 5, the disease is self-limiting, the course of the disease is generally 7-10 days. Only a small number of immunocompromised individuals develop complications, such as chickenpox pneumonia, encephalitis, myocarditis, etc. Treatment: First of all, pay attention to rest, strengthen nutrition, avoid spicy and oily diet, drink more water, avoid scratching and prevent bacterial infection. Secondly, you can use topical soothing and anti-itching agents such as furnace glycolic lotion, internal anti-viral drugs and immunity-boosting drugs, etc. Severe chickenpox requires hospitalization. Precautions: 1, because the disease is contagious, avoid contact with healthy babies, do not go to places with a lot of people to prevent transmission; 2, wear loose and soft clothing, should not be too tight; 3, avoid wind and cold, should not bathe too often; 4, closely observe the condition, if there are changes in the condition, to follow up to prevent the emergence of complications.
