Chickenpox is a highly contagious disease caused by the varicella-zoster virus (VZV). It can cause an itchy, blister-like rash. Chickenpox can be serious especially in babies, adolescents, adults, pregnant women, and people with a weakened immune system. The best way to prevent chickenpox is to get the chickenpox vaccine.
IgM antibodies are the first antibodies to appear in response to initial exposure to an antigen. A positive IgM result indicates it is likely that you have become infected with the varicella-zoster virus within recent weeks.
