Chickenpox is highly contagious. What should I do?
Chickenpox is an acute infectious disease caused by varicella-zoster virus, which was originally infected. It is a common and highly contagious disease, which is mainly spread by saliva droplets, and can also be caused by contact with clothes, toys and utensils contaminated by varicella virus. 9% of susceptible children will get sick after being infected with varicella virus. Spring is the high incidence season of chickenpox, which is highly contagious. Chickenpox patients are the only source of infection. Children infected with chickenpox virus go through an incubation period of about 2 weeks. Children will have fever, headache, physical discomfort, loss of appetite and other precursor symptoms.
After a few hours or a day, children will gradually develop characteristic red papules and blisters the size of rice grains. After 3-5 days, the blister becomes turbid and starts to scab. Chickenpox usually takes 7-14 days from fever to rash, blister, scabbing and scabbing. The most effective way to prevent chickenpox is to vaccinate chickenpox vaccine in time. Children who have not been vaccinated against varicella can prevent varicella by vaccination. Open the window regularly for ventilation to keep indoor air circulation.
Chickenpox and herpes zoster are caused by the same virus-varicella zoster virus. The initial infection is characterized by varicella, and then the virus can stay dormant in the spinal root ganglion for a long time. After the immune function is weakened, it can induce varicella zoster virus to move and grow again, and herpes zoster appears along the affected skin and peripheral nerves. Patients with herpes zoster generally gain lifelong immunity to the virus. The infection period of chickenpox is generally from chickenpox virus infection to chickenpox scab peeling; Chickenpox can be papules, herpes and ulcers, and the scab is pure at the same time, and the scab stage is the most infectious. Once the scab skin falls off completely, it is no longer contagious.
