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.

Early symptoms of chickenpox

The early symptoms of chickenpox generally include fever, and the rash appears as red papules. Later, it can lead to the development of vesicles. In the initial stage of chickenpox, some precautions need to be taken for children, such as avoiding exposure to wind, keeping children away from crowded places, and ensuring a light and easily digestible diet with plenty of fresh vegetables and fruits, such as broccoli, tomatoes, bitter melon, etc. Regarding care, the room should be ventilated for two hours every day to ensure fresh air. Since chickenpox is caused by a viral infection, some antiviral traditional Chinese medicines can be administered to the child for treatment.

Can you get the chickenpox vaccine if you have a cold?

Vaccination is generally required when the baby is healthy, as most vaccines are antigens introduced into the human body to elicit an antibody response from the immune system. If a baby has a cold, it indicates a weaker immune resistance and possible bacterial or viral infection. Vaccinating in such a condition could potentially worsen the cold due to the already compromised immune system and may lead to other side effects such as high fever, rashes, or even other infections. Therefore, it is not recommended to vaccinate while the baby has a cold. It is better to wait a few days until the cold symptoms have completely subsided before vaccinating. Generally, delaying vaccination will not affect the baby and will be rescheduled according to the plan. Thus, it is best not to vaccinate when the baby has a cold.

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.

How is chickenpox transmitted?

Chickenpox is caused by the varicella-zoster virus infection, and it can be transmitted in two ways. One way is through the secretion of the nasopharynx, such as contagious droplets spread by coughing, sneezing, or talking, which can infect people nearby. The fluid from the blisters of chickenpox is also contagious. The primary rash of chickenpox consists of blisters, and before these blisters dry up and crust over, touching the fluid from these blisters can also transmit chickenpox. Therefore, patients with chickenpox need to be isolated until the blisters dry and form crusts before quarantine can be lifted.
