Chicken Pox Immunization

Chicken pox is the common name for varicella simplex, classically one of the childhood infectious diseases and taken by most children survived.

Chickenpox is caused by the varicella-zoster. It starts with moderate fever and characteristic spots appearing in two or three waves, mainly on the body and head rather than hands and becoming itchy raw pox (pocks), small wounds that heal without leaving scars.

Chickenpox is an incubation period of two weeks and is highly contagious by air, two days before the onset of symptoms. Therefore, chickenpox spreads quickly through schools and other places of close contact. Once someone has been infected by the disease, they usually develop protective immunity for life. It is quite rare to get chickenpox several times, but it is possible for people with immune irregular. Because the disease is more severe cases contracted by an adult, parents have been known to make sure their children are infected before adulthood.

The disease can be fatal. Pregnant women and people with depressed immune systems are most at risk. Death is usually from varicella pneumonia. United States, 55 percent of chickenpox deaths were among more than 20 years. Pregnant women do not know at the shelter and come into contact with chickenpox should contact their doctor immediately, because the virus can cause serious problems for the fetus.

A vaccine against chickenpox has been available since 1995 and is now mandatory in some countries for children to be admitted to primary school. In addition, effective medications (eg, acyclovir) are available to treat chickenpox in healthy and immunocompromised individuals. Calamine lotion is often used to relieve itching and paracetamol to reduce fever. Aspirin is not recommended in children with chickenpox because it can lead to Reye's syndrome.

Chickenpox is a highly contagious infection that spreads from person to person by direct contact or by air from an infected person coughs or sneezes. Touching the fluid from a chickenpox blister can also spread the disease. One person with chickenpox is contagious 1-2 days before the rash appears and until all blisters have formed scabs. This may take between 5-10 days. It takes 10-21 days after contact with an infected person for someone to develop chickenpox.

The vesicles of chickenpox begin as a small red papule which develops an irregular outline in the shape of a rose petal. A thin wall of the gallbladder clear (dew drop) develops over the area of redness. This fall "of dew on a rose petal" lesion is very characteristic of chickenpox. After about 8-12 hours the fluid in the gallbladder and gallbladder disorder breaks leaving a crust. The liquid is highly contagious, but once the lesion crusts over, it is not considered contagious. The crust usually falls off after seven days, sometimes leaving a scar crater.

Even if a lesion goes through this complete cycle in seven days, another characteristic of chickenpox is that the cultivation of new lesions every day for several days. Therefore, it can take about a week until new lesions stop appearing and existing lesions crust over.

Second varicella infections occur in immunocompetent individuals, but they are rare and seldom severe.

Vaccination in Japan was among the first countries to routinely vaccinate against chickenpox. Routine vaccination against varicella-zoster is also performed in the United States, and the incidence of varicella was significantly reduced from 4 million cases per year in the pre-vaccine era to approximately 400,000 cases per year from 2005.

The vaccine is extremely safe: about 5% of children who receive the vaccine fever or rash, but there was no death in May 2006 due to.
