Picture of Varicella Chicken Pox
Chicken pox. Chicken pox is an extremely contagious infection caused by the varicella-zoster virus. While these poxes are on the back of an adult, it usually affects kids. The red rash is very itchy and usually has blisters that crust over after several days. Scratching the sores can cause scarring. Once infected, the varicella-zoster virus stays in your body and can erupt later in life as shingles.
