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.

What is chickenpox?

Chickenpox is a contagious disease caused by the varicella-zoster virus, commonly seen in children and prevalent in the spring season. The only source of infection is individuals with chickenpox. It spreads through respiratory droplets and direct contact. The disease is highly contagious and the general population is susceptible, but once recovered, long-lasting immunity is acquired. Clinically, symptoms may include mild fever, headache, fatigue, sore throat, cough, and loss of appetite, lasting for one to two days before the appearance of a rash. The rash first appears on the trunk and then spreads to the face and limbs. Chickenpox rash usually appears in batches, so at the same site, maculopapular rash, vesicles, and crusts can be seen. The crusts typically fall off about a week later, generally leaving no scars. Chickenpox is a self-limiting disease and typically resolves on its own in about ten days.

What are the symptoms of chickenpox?

Chickenpox is caused by infection with the varicella-zoster virus and is highly contagious. The symptoms of chickenpox mainly include fever and rash. The fever is usually mild and may be 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, with the limbs being relatively less affected. Initially, the rash starts as red maculopapular lesions, which turn into vesicles within a few hours. The chickenpox rash appears in batches. The same area can show maculopapular lesions, vesicles, and crusts. Chickenpox is a self-limiting disease that usually resolves on its own in about ten days. However, complications such as secondary bacterial infections of the rash, pneumonia, encephalitis, and hepatitis can occur, potentially worsening the condition.

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.

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.
