Chickenpox primarily affects infants and children, and the target group for chickenpox vaccination is mainly 1-12 years old. During this age period, most children enter preschool or elementary school institutions, and the chickenpox virus is highly contagious, transmittable through droplets and contact. Once one child contracts chickenpox, the surrounding children are almost certain to be infected too. Additionally, since there are currently no effective medications to cure chickenpox, it is best to vaccinate within this age range, namely 1-12 years old. Adults can receive the chickenpox vaccine without age restrictions. The timing can be decided based on individual circumstances, but it is generally recommended to get vaccinated before the onset of the peak season for chickenpox, which is best before the spring and winter seasons.

What are the symptoms and treatments for chickenpox in children?

Symptoms of chickenpox in children vary with age. Infants often show no symptoms or only mild symptoms, which can include mild fever, irritability, and refusal of breast milk, accompanied by a rash. Older children may experience mild fever, headache, fatigue, sore throat, coughing, and decreased appetite. These symptoms persist for one to two days before a rash appears. The rash initially appears on the trunk and then spreads to the face and limbs. Chickenpox rashes often emerge in batches, so the same area may show maculopapular lesions, vesicles, and crusts at the same time. The crusts typically fall off about a week later, usually leaving no scars. Secondary bacterial skin infection, pneumonia, encephalitis, and hepatitis are possible complications. In terms of treatment, infected children should be isolated until all the vesicles have crusted over. During the fever, they should rest in bed, consume an easily digestible diet, stay hydrated, and practice enhanced skincare to prevent infection of the vesicles. Antiviral treatment within 24 hours of rash onset can control the progression of the rash and speed up recovery. If a secondary bacterial infection develops, antibiotics should be used. In cases where encephalitis causes cerebral edema, dehydration treatments should be administered. The use of corticosteroids is not advisable for treating chickenpox.

The differences between measles and chickenpox

Measles and chickenpox, though both are diseases caused by viral infections, have clear differences. Measles is caused by the measles virus, while chickenpox is caused by the varicella-zoster virus. Furthermore, measles generally begins with a fever, and after a few days of fever, red spots and papules appear, whereas with chickenpox, clear vesicular papules appear initially on the trunk or limbs.

Symptoms and Treatment of Chickenpox in Children

Chickenpox is an acute, contagious, exanthematous disease caused by varicella-zoster virus infection. Before the rash appears, symptoms such as fever, discomfort, and loss of appetite may occur. The fever typically lasts about one day before the rash emerges. The rash initially appears on the head, face, and trunk with a centripetal distribution. The rash can present as macules, papules, vesicles, and crusts all appearing simultaneously. Rashes can also appear on the mucous membranes of the mouth and the genital area. The treatment for chickenpox involves symptomatic and supportive care, and antiviral medications may be used appropriately to protect the skin and prevent scratching.

What should be paid attention to when children have chickenpox?

Chickenpox is a self-limiting disease, and when there are no complications, treatment generally focuses on symptomatic relief. During illness, isolation should be maintained to prevent infection and enhance care, such as frequently changing underwear, trimming the child's nails, and wearing gloves to prevent scratching. Keep the air well-ventilated, provide sufficient fluids and easily digestible food. If a secondary bacterial infection occurs, antibiotic treatment should be administered. The child should be isolated until all the rash has crusted over.
