One common childhood disease in children, chicken pox is very reputable for being contagious.
A child infected with chickenpox virus will develop a lot of itchy blisters which are filled with fluid. These blisters burst eventually, which lead to crusts formation.
Children get roughly five hundred such blisters which develop over a red skin area. They appear on the face first and then multiply to the trunk, scalp and the rest of the body.
After twenty four hours of appearance, the fluid packed blisters become cloudy and later on, scabby.
The itchiness triggered due to chicken pox is really intense and irritating. And the crust, if not taken care of, can leave scars for life.
