Definition and causes
Chickenpox (varicella) is a highly contagious, but mild process of viral disease, caused by infection with the virusvaricella-zoster. The disease causes fever and a rash characteristic in the central area of the body. In rare cases, it may impede the airways.
Varicella-zoster virus spreads by inhaling virus particles from infected persons or by close contact with a person with a damaged skin, where there is this virus.
