How to prevent chicken pox?
Chickenpox is a highly contagious rash disease in children caused by varicella-zoster virus. Chickenpox is mainly transmitted by airborne droplets. Patients are the only source of infection.
After suffering from chickenpox, there will be precursor symptoms such as low fever, fatigue and upper respiratory symptoms. Twenty-four hours later, the rash began to turn into a red rash, which quickly developed into a clear oval teardrop blister with redness around it, lasting for 3-4 days, and then began to shrink and scab. The rash is mainly located in the trunk and less in the limbs. Chickenpox rashes appear in batches, so rashes at each stage can appear at the same time.
After suffering from chickenpox, he generally recovered well. After some patients suffer from chickenpox, the virus can lurk in the ganglion for a long time. Herpes zoster can be caused when the immunity decreases or some incentives activate the virus.
It is suggested that patients without complications still need symptomatic treatment, such as antipyretic, local or systemic use of antipruritic and sedative drugs; Antiviral drugs can be selected under the guidance of doctors; Strengthen nursing, keep skin clean, change underwear frequently, cut the nails of sick children short to prevent secondary infection from scratching blisters; If there are complications, such as pneumonia, encephalitis, rash and secondary infection, etc. You should see a doctor in time.
Clinical manifestations (symptoms, etc.). ) chickenpox is not serious, but it is highly contagious. It is mainly transmitted through direct contact with varicella herpes fluid and respiratory droplets, and can also be transmitted through appliances (including toys) contaminated by viruses. 90% of susceptible children can get sick after contact. After infection, it must be isolated until all rashes are dry and scabbed. Because spring and winter are the high-incidence seasons of chickenpox, kindergartens, schools and other collective units should pay attention to regular indoor ventilation and wet cleaning, strengthen morning and afternoon inspection, find suspicious cases in time, isolate and treat them as soon as possible to avoid multiple occurrences and outbreaks. Vaccination with varicella vaccine is the best way to prevent varicella. Before children enter kindergarten or school, a dose of varicella vaccine can reduce the risk of varicella transmission by choosing an immunization clinic near their place of residence.

4. What are the common sense of chickenpox?
Chickenpox is an acute infectious disease caused by varicella-zoster virus.
Most of them occur in winter and spring. Mainly by sneezing.
Cough droplets, spread through the respiratory tract, can also get sick because of contact with toys, clothes and utensils contaminated by viruses. A disease can get lifelong immunity.
The clinical manifestation is a history of contact with chickenpox within 2-3 weeks before onset, and the symptoms before eruption are mild, including low fever, runny nose, cough, discomfort and other symptoms. Rashes often appear on the day or the next day, followed by maculopapules on the skin and mucous membranes of the whole body, which develop into blisters and itching within a few hours, and dry and scab after 1-3 days. The rash appeared in batches within 3~4 days, mainly distributed in the trunk, head and face, with fewer limbs.
Moreover, maculopapules, papules, herpes and scabs can coexist in the same place at the same time. Chickenpox is generally mild, and pneumonia and otitis media may occur in some cases.
Children with chickenpox should be isolated immediately after life adjustment (1), and the isolation period is from onset to rash scabbing. (2) Children with acne should pay attention to bed rest, strengthen nursing, wash their hands frequently, and cut their nails to avoid scratching the rash and causing secondary infection.
(3) Pay attention to diet aftercare, eat light and digestible food, drink boiled water, and avoid spicy and greasy food.

Chickenpox is highly contagious, and patients are the only source of infection. About 90% of children who come into contact with it will get sick.
In addition, it is contagious from the day before the onset to the dry scab of all rashes. Chickenpox is more acute, and there may be systemic symptoms such as fever, fatigue and loss of appetite. Adults are more obvious than children, and rashes usually appear within 1~2 days.
Chickenpox generally occurs in the trunk first, and gradually spreads to the head, face and limbs, showing a centripetal distribution, that is, there are more trunks, fewer facial limbs, and fewer palms and soles. At first, it was a small red pimple, and after a few hours, it turned into a blister the size of mung bean, and the surrounding area was flushed.
Blisters are clear water droplets at first, with thin and fragile walls and itching. After 2~3 days, the scab shaft healed without leaving scars.
Within 3~5 days after the onset of chickenpox, rashes appear in batches, so papules, blisters, scabs and other skin lesions in different periods can occur at the same time, and the course of disease is about 2~3 weeks.
6. Small class health teaching plan: "How to prevent chickenpox"
Activity preparation: 1, a chicken pox prevention poster.
2, "poster" shows the prevention method of chickenpox. Activity flow: 1. Show pictures and learn about chickenpox. (1)- Teacher: "Honey, where did you see the child in the picture get sick?"

Patients and virus carriers are the main sources of infection of this disease.
Through air and droplets, sick children's oral cavity and nasal cavity contain a lot of varicella virus. When coughing or sneezing, the virus is sprayed into the air, and healthy babies will get sick after inhalation. It can also be infected by touching or using patients' tableware, toys, clothes, quilts, towels, etc. This disease is highly contagious. 2, read the report, understand the main symptoms of chickenpox "got chickenpox, what symptoms and reactions will appear in the body?"

7. Can you tell me the medical knowledge about chickenpox?
Chickenpox is a highly contagious rash disease, which is spread by contact or droplets. Almost all susceptible children can get sick after contact with varicella children, and gain lasting immunity after infection, but herpes zoster may occur in the future. Winter and spring are frequent.
Etiology and pathogenesis:
The pathogen is varicella-zoster virus, that is, human herpesvirus type 3. Viruses have weak viability in the external environment, are not resistant to high temperature and acid, and cannot survive in crusts. Chickenpox virus invades the human body through the nasal cavity, first proliferates in respiratory mucosa cells, and then enters the blood after 2-3 days, leading to viremia. It can proliferate again in the monocyte-phagocyte system, then enter the blood to cause the second viremia, and then spread to the whole body, causing pathological changes of various organs. The main injury site is the skin. Occasionally accumulate internal organs. After eruption 1~4 days, specific cellular immunity and antibody were produced, viremia disappeared and symptoms were relieved.
Pathology:
Herpes is confined to the stratum spinosum of epidermis, showing degeneration and edema. Blisters are formed due to cell dissolution, liquefaction and careful entry of tissue fluid. Mucosal lesions are similar to rashes. People with immune deficiency or suppressed immune function can develop generalized chickenpox, and the lesion can spread to respiratory tract, esophagus, stomach, lung, liver, spleen, pancreas, adrenal gland and intestine. The affected organs may have focal necrosis and obvious inflammatory cells, and multinucleated giant cells containing eosinophilic inclusions can be seen. Complicated with brain edema, congestion and punctate bleeding.
