Chicken Pox Chickenpox, which is caused by the varicella-zoster virus, is highly contagious, and it can spread quickly. The virus is transmitted by direct contact with the rash or by droplets dispersed into the air by coughing or sneezing. The chickenpox rash goes through these three phases: Raised pink or red bumps (papules), which break out in different spots over several days Fluid-filled blisters (vesicles), forming from the raised bumps over about one day before breaking and leaking Crusts and scabs, which cover the broken blisters and take several more days to heal Fever and loss of appetite is common A vaccine is available and is usually given during childhood.
