Chickenpox is a highly contagious illness. Although people generally recover from chickenpox, it can cause serious complications in some people. Chickenpox was a common childhood illness prior to the introduction of the vaccine against chickenpox.
Signs and symptoms of chickenpox include a rash that is extremely itchy. The rash has red spots that can turn into fluid-filled blisters that eventually form a crust. The rash usually begins on the head or trunk and then spreads to other areas of the body. Other associated signs and symptoms of chickenpox include fever, headache, sore throat, fatigue, reduced appetite, and malaise.
