The classic rash of chicken pox infections, include red papules (bumps), vesicles (the spots that look like little blisters), which then become crusted scabs.

Chicken pox typically starts on a child's trunk and then spreads to the rest of their body, including their arms, legs, and head.

Other symptoms of chicken pox typically include a prodrome of fever, malaise, headache, lack of appetite, and mild abdominal pain for 1 to 2 days.

It is very itchy and very contagious, but can be prevented with a chickenpox vaccine.

Keep in mind that the current immunization schedule advises that kids get a chicken pox booster shot beginning when they are four years old, which should help to further decrease chickenpox infections.
