What is the incubation period for chickenpox -symptoms, features

Update: October 2018

Ветрянка  – относится к острым, высокозаразным вирусным
infections that are easy enough to diagnose because
characterized by very characteristic symptoms. The main symptom of the virus
is an:

  • rash
  • itch
  • heat
  • chills
  • loss of appetite
  • headache
  • increase in regional lymph nodes

A rash in one day turns into a blister, and after 2 days
rashes on the skin look like “dew drops” with a transparent
content. After 2 days the contents become cloudy and soon the bubble
dries, turning into a crust. The crust disappears in 1-3
of the week. Itching may be of varying intensity.

If the antiseptic treatment is constant and is performed
correctly, the rash does not leave scars. But if the processing is not
possible secondary infection with lesion
the enzymatic layer. Then after the rash scars, scars,
almost like smallpox, but not so gross.

Features of chickenpox virus

quickly dies, unstable in the environment, dies from
disinfectants, UVI, from low and high temperatures. But at
room temperature lasts up to several hours. The virus is very
volatile and can overcome up to 20 meters, getting on ventilation with
floor to floor Even fleeting contact leads to infection.
human, most often the chickenpox appears in autumn and winter,
epidemics are recorded every 5 years. Children most often get sick 5-10
age, adults get sick less often (contagiousness of the disease
high, therefore not ill adults catch also easily, but
suffer a disease much harder). Many are interested in – how much
Is chickenpox contagious in time? When is chickenpox contagious?

Chickenpox incubation period

Chickenpox incubation period длится 10 — 21 день. In adults he
may be longer, in weak children – in short. Average
It is believed that chickenpox in children has an incubation period of 14 days,
and the incubation period for chickenpox in adults is 16 days.
In that
period the pathogen penetrates through the upper respiratory tract,
multiplies and accumulates in the epithelial cells of the mucous membranes
respiratory tract.  Whole chickenpox incubation period
can be divided into three periods:

  • The start of the incubation period is the period when it happened.
    infection and the virus has adapted in the patient.
  • The development of the incubation period – the phase of reproduction and accumulation
    pathogen when the primary focus of infection is formed, with
    distribution along the periphery.
  • The final period of the incubation period of chickenpox –
    spread of the virus throughout the body, the production of antibodies to
    pathogen. The appearance of the first signs of the disease.

In the final period in the patient’s body at the cellular level
production of protective antibodies to the pathogen occurs. Yes,
very cunning chicken pox, its incubation period is very long,
it is therefore quite difficult, at times, to determine where, when and from whom
an infection has occurred.

Manifestations of the disease begins with a rash in the form of pink
nodules on the scalp and face. Затем rash
spreads throughout the body in a matter of hours, striking the skin
between the fingers, and even the mucous membranes of the patient – mouth, eyes, genital
organs. Itching in these places is the most disturbing and
inconvenience. The rash and temperature persist for about 6-10 days,
after which the crusts fall off, and the skin is cleared from the rash. Have
recover from chickenpox life-long immunity to this
virus.

How do you get chickenpox?

Transmission of chickenpox virus occurs exclusively
by airborne droplets, that is, not transmitted by households,
through objects, and so on. When the bubbles are opened, it can be infected through
skin, but it rarely happens. You do not need to be protected from infection
sanitize everything in the apartment, you only need not to communicate with
sick

How many days is chickenpox contagious?

An infected child may be contagious before
the first rash will appear, namely, the last 10 days
инкубационного периода (перед rashю). From this period until
until the last crust disappears, it can infect
surrounding Therefore, it turns out that chickenpox, a contagious period
which is quite long, 11-21 days, is very contagious
disease.

How not to get chickenpox?

To not get infected, you should not take a child to kindergarten, if
there is quarantine for chickenpox, a protective mask in this case
does not give a 100% security guarantee. Many doctors believe that
it is better to have time for this “children’s infection” because
adults and adolescents tolerate chickenpox with
high fever and complications.

The risk of complications is especially high in unimmunized adults,
There are those who have not been ill in childhood and have not been vaccinated from wind
smallpox. Chickenpox is dangerous for pregnant women due to possible
disability of the child, for infants from unimmunized
mothers. In such cases, severe forms of the virus can develop:
gangrenous, hemorrhagic form, bullosa.
