What kind of disease is chickenpox? How chickenpox is caused

<> chickenpox is an acute infectious disease in children caused by a special varicella virus (varicella-zoster virus). The chickenpox virus exists in the early stages of the respiratory tract of patients with chickenpox. In general, people are contagious from 1 day before the rash to 5 days after the rash or before the rash is completely crusted and dry.

It is mainly transmitted through saliva droplets, but it can also be contracted by contact with clothes, toys, utensils, etc. contaminated with chickenpox virus. Most of the patients are children aged 1 to 5 years, and the infants within 6 months have temporary immunity due to the acquisition of antibodies from the mother. It can occur all year round, especially in winter and spring.

Collective children's institutions, nurseries and kindergartens are prone to local walks.

From infection with the chickenpox virus to the onset of symptoms, it takes about 14 to 21 days, and most often 15 to 17 days. Symptoms may be mild, but may include mild fever, malaise, loss of appetite, cough or mild diarrhoea. At the same time as fever or after 1 or 2 days, a red rash appears on the trunk**, which turns into small blisters containing translucent fluid after a few hours, called herpes.

Herpes is generally oval-shaped, of different sizes, superficial, as if floating on the surface, often accompanied by itching, making the child irritable. Within 1 to 3 days, the center of the herpes begins to dry and dent, forming a crust, and after a few days the scab falls off naturally without leaving a scar. A small number of herpes leave traces due to a secondary bacterial infection due to scratching.

Chickenpox is caused by the varicella-zoster virus, which tends to occur in winter and spring and is highly contagious. Most chickenpoxes don't need it, but some can be life-threatening. Fever, various types of itchy rash, oral cavity and scalp involvement are generally present:

Fever and malaise begin first. A rash appears about 2 days later, starting on the trunk and gradually spreading to the head, face and limbs. It begins with pruritic erythema and papules, and develops into blisters after 12 to 14 hours.

The rash appears in clusters and may have papules, blisters, pustules, and crusts at the same time. Oral and scalp involvement is helpful in the diagnosis of varicella. Occasional complications can be life-threatening:

Generally, chickenpox is self-healing, has no sequelae, and has a good prognosis. Although the incidence of serious complications is low (about 1 1000), once they occur, they are more damaging to the body and even life-threatening, including: ** soft tissue bacterial infection, pneumonia, encephalitis, hemorrhage (thrombocytopenia), sepsis, sepsis, etc.

Serious morbidity and mortality are higher in immunocompromised populations. Self-healing in 2 weeks: If there are no complications, chickenpox in most healthy people will heal on its own in 2 weeks.

Antiviral** significantly improves symptoms and shortens the duration of the disease. Generally not**: After infection, the body will produce long-lasting immunity, as long as it is a person with normal immunity, most of them will not be re-infected, that is, they will not be "**".

Despite this, there are still a small number of people who are reinfected with "**", and the symptoms of recurrence will generally be mild.

Chickenpox is an acute infectious disease caused by primary infection with the varicella-zoster virus. The contagion rate is high. It occurs mainly in infants and young children, and is characterized by fever and clusters of erythematous maculopapular rashes, herpes, and crusts.

It occurs frequently in winter and spring, and its contagiousness is strong, and it can be transmitted by contact or droplets. The incidence rate of susceptible children can reach more than 95%, and it is more common in preschool children. Clinically, it is characterized by the appearance of maculopapular rashes, blisters and crusts on the mucous membranes in batches, and the presence of rashes at the same time.

The disease is self-limiting and can lead to lifelong immunity or herpes zoster years later**.

Chickenpox is highly contagious. The patient is the only source of infection, and the infectious period usually extends from 1 to 2 days before the rash appears until the herpes crusts over completely. Immunocompromised patients may be contagious throughout the course of their illness.

Chickenpox can also occur in children who come into contact with someone with shingles, because they are the same. The main route of transmission is respiratory droplets or direct contact. It can also be exposed to contaminated materials.

Chickenpox It is caused by the chickenpox virus, which is a virus that causes infections throughout our body. First of all, it is transmitted through the respiratory tract in the outside world, and you say that there is a person opposite you, and he has chickenpox, and then you have contact with him, then this chickenpox virus spreads through the respiratory tract and enters your airway, and then it enters the airway at the same time, and it is customized locally, and after customization, it enters our bloodstream, in the bloodstream, and then includes it behind it and enters our lymph nodes, and enters all of our systems throughout the human body, and then it makes a customization. At the same time, it eventually causes some reaction in our body, what reaction? Fever.

It's that our human body doesn't recognize this virus, so a foreign molecule comes, and I have a fever, and I want to get rid of it, fever. The second appears, a rash. It's that there are many, many small rashes on the body, some red rashes, then this rash is quite distinctive, this rash means that I and I have come out for a certain period of time, it will be a fusiform such a red rash, and there is a shiny little blister on the red rash, so this is the origin of the name of chickenpox.

Hello, chickenpox is an acute infectious disease caused by the initial infection of the varicella-zoster virus. It is characterized by fever and clusters of erythematous maculopapular rashes, herpes, and crusts. The disease is self-limiting, and lifelong immunity is conferred after illness.

It is caused by the herpes zoster virus.

fever, fever, rash on the trunk, face, etc., blisters on the ears and mouth; Some children do not have fever. The rash that appears due to chickenpox is red around the perimeter with scald-like blisters in the middle and yellow liquid in the blisters.

Chickenpox symptoms: Chickenpox usually has a fever for 1-2 days, and the rash starts as red macules, papules, and after a few hours, these maculopapular rashes quickly turn into fluid-filled herpes.
