What is chickenpox?

ANSWER

Chickenpox is a common illness caused by the varicella-zoster virus. Symptoms of chickenpox include fever and itchy spots or blisters all over the body. Chickenpox is usually mild and runs its course in five to 10 days, but it can cause more serious problems when teens and adults get it. People with weakened immune systems are especially susceptible to developing serious complications from chickenpox.
