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.

After infection with the chickenpox virus will run along the følenerverne for their grains (ganglier) and go at rest. Later in life may virus break out again as the disease shingles (herpes zoster). This occurs most often caused by other illness, stress or of old age.

Chickenpox is in Denmark mainly a childhood (traditionally belonging to the four classic childhood diseases), and 90 percent are believed to have been in the teens. In tropical countries is also seen cases of chickenpox in adults.

Symptoms of chickenpox

Precautions and diagnosis

Chickenpox is usually a mild progress and moving by itself. One should go to the doctor if you feel very ill and are unsure of what one fails.

Pregnant women who have not had chickenpox and develop the disease (in the first part of pregnancy) should immediately go to the doctor, as the disease can damage the unborn child. Pregnant women with the disease may have a specific medical instrument (immunoglobulin).

Doctors can usually make the diagnosis, according to the characteristic skin rash.
