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.
People with chickenpox are contagious a day or two before the rash appears and until all blisters have formed scabs. In children, chickenpox most commonly causes an illness that lasts about 5-10 days. Children usually miss 5 or 6 days of school or childcare due to their chickenpox.Their symptoms may include high fever, severe itching, an uncomfortable rash, dehydration, and headache.he name was meant to distinguish this weak form of the pox from smallpox. Chicken is used here, as in chickenhearted, to mean weak or timid. The pox of chickenpox is no major matter unless it becomes infected (through scratching) or occurs in an immunodeficient person.
