Chickenpox is an infection caused by the varicella-zoster virus. It causes a rash with small, fluid-filled blisters. The rash starts 10-21 days after exposure to the virus, and lasts for 5-10 days. New bumps come on over several days, and then crust over. Chickenpox is also associated with fever, decreased appetite, headache, and fatigue.
Chickenpox is usually a mild disease. In some cases it can have complications such as bacterial infection of the skin, dehydration, or pneumonia. Chickenpox can cause serious problems in women who are pregnant and people with immune system problems. There is a vaccine that prevents 98% of chickenpox infections.
