Chicken Pox


Chickenpox (Varicella zoster)
also know as varicella, is one of the most common disease among kids caused by a Herpes Zoster virus (human herpes virus 3). It usually affects kids between 5 and 10 years although everyone can develop this disease no matter the age. It stikes in the spring time most oftenly.

There is vaccine that can successful prevent chickenpox.

Although this disease is very easy to handle it can be very dangerous for people with AIDS, a lowered immune system, and pregnant women.(it can lead to many problems with fetus including physical deformities, neurological disorders and damage of brain, eyes and skin).

Infection is very contagious so there is very small number of people who didn't have it. Infected children should stay in quarantine (usually at home) because disease spreads easily through air.

Chickenpox incubation period is 10-14 days and two days before symptoms occur it becomes contagious.

After disease is gone Herpes Zoster virus stays in the bodys nerve tissues but it's kept under control by immune system. Sometimes (in about 10% of cases) it can reactivate later (usually in adults) and cause shingles (paintful blisters over the skin).


Chickenpox rash consists of small blisters that start as 2-4 mm red papule developing an irregular outline in the form of rose petal. On the top of area develops clear vesicle filled with fluid which breaks after 8-10 hours leaving a crust. This process continues for about 7 days. Patient is contagious until all lesions have crusted over.
It's highly recommended not to scratch those lesions because they can cause scars or infections. This can be difficult to prevent in the cases of small children.
Its very important for patient to maintain personal hygiene and be in clean enviroment.
Aspirin should never be used during chickenpox because it can cause serious problems.
Besides rash patient with chickenpox may also experience fever, cough or breathing troubles, problem looking at bright lights, stiff neck, vomiting, hard waking up, headache, fatique.
