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.

Initial symptoms of chickenpox in children

Chickenpox is a contagious respiratory disease caused by a virus, characterized by a rash. Initially, symptoms resemble those of upper respiratory infections such as coughing, runny nose, mild fever, and decreased appetite. Subsequently, maculopapular rashes appear on the scalp and face, which gradually develop into vesicles. These vesicles contain a clear fluid, surrounded by reddened skin and are accompanied by itching. Therefore, if a child exhibits symptoms of an upper respiratory infection followed by vesicular rash, it is important to seek medical advice promptly to confirm if it is chickenpox. If diagnosed with chickenpox, isolation is necessary to prevent cross-infection.

How is chickenpox treated?

The symptoms of chickenpox often present no symptoms in infants and toddlers, but they may experience low fever, irritability, and reluctance to breastfeed. Simultaneously, a rash appears. In older children and adults, symptoms can include low fever, headache, fatigue, sore throat, cough, and loss of appetite, followed by the appearance of a rash after one to two days. The rash first appears on the torso and then spreads to the face and limbs. Since chickenpox rash typically appears in batches, at the same site one may see maculopapular rashes, vesicles, and scabs. About a week later, the scabs fall off, generally leaving no scars. However, secondary bacterial infections of the rash can occur, leading to complications such as pneumonia, encephalitis, and hepatitis. Chickenpox is a self-limiting disease that usually resolves itself in about ten days. Treatment of chickenpox involves isolating the patient until all the blisters have completely scabbed over. During the fever phase, bed rest is recommended, along with easily digestible food and adequate hydration. Skin care should be emphasized to prevent infection. Early antiviral treatment can be effective, particularly if administered within 24 hours of the appearance of the rash, as it can help control the rash's progression and accelerate recovery. In cases of secondary bacterial infection, antibiotics should be used. If encephalitis leads to cerebral edema, dehydration treatment should be administered. The use of corticosteroids is not advisable for chickenpox as they can cause the disease to spread.

Chickenpox Symptoms and Treatment Methods

Chickenpox is caused by an infection with the varicella-zoster virus and is highly contagious. The symptoms of chickenpox mainly include fever and rash. The fever presents as a low-grade fever, possibly accompanied by chills, headache, fatigue, sore throat, and loss of appetite. These symptoms last for one to two days, followed by the appearance of a rash. The rash first appears on the trunk, then on the head and face, and is relatively less common on the limbs. It begins as red maculopapular rash and turns into vesicular rash within a few hours. The chickenpox rash appears in batches, and maculopapules, vesicles, and crusts can be seen in the same area. Chickenpox is a self-limiting disease that can be cured in about ten days. Patients should be isolated until all the vesicles have crusted over. Early in the course of the disease, antiviral treatment with acyclovir can be used. It is important to keep the skin clean and avoid scratching the vesicles to prevent infection.

Chickenpox prevention measures

Chickenpox is an acute infectious disease, and prevention of the infection mainly involves the following three aspects: First, control the source of infection. Patients with chickenpox are the only source of infection, so they should be isolated until all the chickenpox blisters have crusted over. Second, cut off the transmission route. Avoid close contact with chickenpox patients, prevent airborne droplet transmission, and avoid contact with items contaminated with the chickenpox virus. Third, protect susceptible populations. Chickenpox is highly contagious and generally susceptible in the population. Infants over one year old can be vaccinated with the chickenpox vaccine for prevention. Regular exercise, nutritional enhancement, physical strengthening, frequent hand washing, and maintaining ventilation in indoor environments are also advisable.
