About Chickenpox

Chickenpox is a highly contagious disease caused by the varicella-zoster virus (VZV). It can cause an itchy, blister-like rash among other symptoms. The rash first appears on the chest, back, and face, and then spreads over the entire body.

Chickenpox can be serious, especially during pregnancy, in babies, adolescents, adults, and people with weakened immune systems (lowered ability to fight germs and sickness).

The best way to prevent chickenpox is to get the chickenpox vaccine.
