Chicken Pox

Chicken pox is not a type of food like fried-chicken, but it's a childhood disease.
In Indonesia language known as cacar air.
Chicken pox mostly affected nearly all children under the age of ten years in all the world. but, sometimes when somebody didn't get chickn pox when he is as a child, chicken pox could affected her or him as adult. A person can only get chicken pox once in a life. When an adult gets chicken pox, the case is usually more severe and lasts longer. Adults are 10 times more likely than children to require hospitalization from chicken pox. Adults who have had chickenpox as a child are less likely to have shingles in later life if they have been exposed occasionally to the chickenpox virus (for example by their children). In the late 1980s, American children were a reported 3.9 million cases of chicken pox each year .
Chicken pox is highly contagious. In England and Wales, 75% of deaths due to chickenpox are in adults. A person with chicken pox is contagious from one to two days before the outbreak of the chicken pox rash, and for six days after the rash erupts. After being exposed, a person will show symptoms of chicken pox within 10-21 days.

Chicken pox caused by the virus named varicella zoster virus.
Symptoms of the disease include a mild fever for one to two days before the appearance of a skin rash (small, watery blisters) that begins on the scalp and body and spreads within three to four days over the entire body.
A typical case of chicken pox involves between 250 and 500 blister over the body. These dry into scabs after three or four days. The blisters are very itchy, and children should be discouraged from scratching and their fingernails should be kept very short for the duration of the chicken pox case. to help relieve the itching of chicken pox usually can using lotion or body powder.
Although complications from chicken pox are generally uncommon, the most common one is bacterial infection of the skin, initiated at the site of a chicken pox blister that has broken or was scratched open. Other complications include viral or bacterial pneumonia and encephalitis (swelling of the brain).
The groups that are at higher risk for developing complications are anyone with a weak immune system, children with lung diseases, children with eczema or other skin conditions; infants under one year of age; premature infants whose mothers have not had chicken pox; and newborns whose mothers had chicken pox around the time of delivery. An oral anti-viral drug, acyclovir, may be prescribed for anyone at risk of developing a severe case of chicken pox. Acyclovir is only effective if it is given within 24 hours of the outbreak of the chicken pox blisters.

Shingles, known medically as herpes zoster, is a condition of the nerves caused by the chicken pox virus that affects between 10-20% of all people who have ever had chicken pox. Once a person has had chicken pox, the virus remains in his or her nerve roots for the rest of his or her life. The virus most commonly reappears as shingles at age 50 or older, although shingles can occur anytime. Shingles cause itching, numbness, or severe pain in skin areas where the affected nerve root is located, and within about three days, causes clusters of blisters to form along the affected nerve. The blisters last two to three weeks.
