Chickenpox (varicella) is a contagious illness that causes an itchy rash and red spots or blisters (pox) all over the body. Chickenpox can cause problems for pregnant women, newborns, teens and adults, and people who have immune system problems that make it hard for the body to fight infection.
Chickenpox is caused by a virus called Varicella Zoster virus. Most children who get chickenpox have a mild illness, but some can become quite ill. The illness with chickenpox usually lasts about 7-10 days. The illness may start with a fever and feeling unwell, like having a cold.
