you life or an itchy time waiting ahead for you, unless you are one of the few lucky ones.

History
Before the sixth century shingles, a secondary infection of chicken pox was
identified. Then after the nineteen century chicken pox was identified as a separate
disease from the smallpox disease. In 1995 the United States Food and Drug
Administration approved the first vaccine against chicken pox. This came after extreme

is in use today and is proven to be safe, it is still under debate if it should be used and if it
is truly safe.
Causes
Chicken pox is caused by the varicalla-zoster virus (VZV). Chicken pox is very
contagious, approximately four million cases occur each year. Breathing in sneezed air
