Beijing CDC monitoring data show that the number of chickenpox will be per year from March every year. Gradually increasing, the incidence will reach the seasonal peak from 5 to June.
what is chickenpox?
chicken pox is an acute infectious disease caused by varicella zoster virus. Chickenpox is the only source of infection. It is transmitted mainly through respiratory droplets and direct contact with varicella herpes.
fever and rash are the main symptoms of varicella. Before the appearance of the rash, children have low fever, pharyngeal pain, fatigue burnout, crying uneasiness, gastric anatoles and other prodromal symptoms.
rash caused by chickenpox is itchy and usually occurs one day after prodrome. At first, rashes were small red rashes or papules with high skin. They looked like small pods or insect bites. Then the rash developed into a thin, full, liquid blister. Then the blister broke and dried to scab. The new rash appeared in batches in the next few days and developed into papules and water herpes.
the characteristic feature of this rash is "four generations together". At the peak of the disease, macula, papules, herpes and scab can be seen simultaneously. Chickenpox rashes often occur on the chest, back and face, and gradually develop into other parts of the body, including scalp, mouth, limbs and external genitalia.
varicella rash in children with eczema may be relatively severe or widely distributed. For older children or adults, the symptoms of younger children are relatively mild, and water herpes are also less.
how does chickenpox infect?
chicken pox is highly contagious, from one day to two days before eruption until the rash is all scab, and the whole course is infectious. Chickenpox can be spread through coughing and sneezing droplets or through direct contact with chickenpox patients (such as blister of herpes). People who have not had chickenpox or vaccinated against varicella will appear rash for the first 2 weeks of the first exposure to varicella virus, and most people will have signs of disease within 10 to 21 days. Does
do chickenpox have complications?
chicken pox is a benign self limiting disease, and only a small number of patients, such as patients with bacterial skin infection, pneumonia and encephalitis, may have complications in small infants or adults with immune damage. What are the treatment measures for
varicella?
varicella is a viral infection and can not be treated with antibiotics, but it can be used to relieve symptoms.
1. relieved the itching symptoms of fever and rash
fever: acetaminophen (Tylenol or byl) can be used to reduce fever. It should be noted that aspirin can not be used to relieve the fever of children with chickenpox. Otherwise, it may cause damage to the brain and liver of Reye's syndrome.
itch: antihistamines can be used to relieve the itching of varicella rashes, such as cetirizine, diphenhydramine and diphenhydramine. At the same time, Calamine Lotion can also be used to relieve itching. Children should be reminded to avoid scratching, otherwise there will be danger of scarring.
oral herpes: children may eat less because of the pain in oral herpes. Parents should encourage their children to take enough liquid to help prevent dehydration and control fever.
2. antiviral therapy
for people at risk of severe chickenpox, such as unvaccinated or immune impaired children aged 12 and over, can use antiviral drugs (such as A Silowe, valaciclovir) to resist varicella virus infection early in the course of the disease.
3. isolation and contact protection
If children suffer from chickenpox, they should be closed and rest at home until the last herpes is scab. Dry scab is not infectious, and most people who have had chickenpox will not be infected again.
