Chickenpox is self-healing in immunocompetent children, and rarely combined with encephalitis, pneumonia, and myelitis, even if complications arise most of them can be cured after treatment, and there are no sequelae. Therefore, children under 13 years of age do not need antiviral treatment for chickenpox. Immunocompromised children and children and adults over 13 years of age are recommended to start acyclovir antiviral treatment within 24 hours. Treatment with acyclovir within 48 hours of onset can shorten the duration of illness and reduce the risk of severe cases such as pneumonia. For adults, oral acyclovir should be given 600 to 800 mg four times a day. Most cases of chickenpox will have itchy skin, which can be relieved by topical application of stove glycolic lotion. A common complication of chickenpox is secondary infection after herpes breakage, so once you see herpes breakage, disinfect with iodophor in time, and if there is skin redness, swelling, pain and other signs of infection, treat the infection with topical anti-infection ointment such as fusidic acid and mupirocin in time. In severe cases of chickenpox or causing symptoms such as thrombocytopenia, treatment with human immunoglobulin can be added and most have a better prognosis. A few will have complications such as encephalitis and myelitis, which can also be treated with hormones and immunoglobulins. However, most chickenpox is a mild disease that can heal on its own in 7 to 10 days, and only symptomatic treatment is needed.
