Chickenpox is a highly contagious febrile rash disease in children that can cause outbreaks. Both varicella and herpes zoster patients are sources of infection, mainly through airborne droplets via the respiratory tract, but also through contact with the patient’s herpes plasma. Durable immunity can be acquired after chickenpox infection, but shingles can occur later, and shingles can recur. The first thing to do after contracting chickenpox is to isolate yourself and avoid infecting your family, colleagues and friends, especially children who avoid infecting their parents. The cause of chickenpox is the varicella-zoster virus, and people who come into contact with patients with chickenpox and shingles may be infected with chickenpox, and chickenpox is very contagious. 90% of people who have not had chickenpox and have not been vaccinated against chickenpox will be infected with chickenpox after coming into contact with people with chickenpox, so It is common to see adults who have chickenpox and soon babies at home who also have chickenpox. The isolation period of chicken pox should be at least two weeks, until all herpes on the body completely scabbed before you can lift the isolation, many schools and kindergartens require isolation until the scabs also completely fall off before you can go to school or kindergarten, rigorous some can not be faulted, but may cause some unnecessary waste. The most important thing to remember is that the elderly have a high incidence of herpes zoster, and many families have children with the elderly, so it is easy for the elderly to infect their children, which further leads to the spread of herpes zoster among children. This can lead to the spread of chickenpox among children. Chickenpox is self-healing for children with normal immunity, and rarely combined with encephalitis, pneumonia, and myelitis, even if there are complications most of them can be cured after treatment, and there are no sequelae, so chickenpox does not require antiviral treatment for children under 13 years old, and it is recommended to start acyclovir antiviral treatment within 24 hours for children with low immunity and children and adults over 13 years old. If the skin is itchy, topical application of stove glycolic lotion can be applied to relieve itching.
