Chickenpox is one of the most contagious childhood diseases of all: so contagious that the pathogen seems almost to be carried „on the wind“ from room to room, which is where its German name comes from. It is caused by the varicella-zoster virus, spread through the air and through the contents of the blisters. Typical is a strongly itching rash with many small, fluid-filled blisters that appear all over the body in waves and finally crust over. For healthy children chickenpox usually runs harmlessly, even if the itching can be tormenting; it is more dangerous for newborns, pregnant women and people with a weakened immune system. A special feature of this virus is that after the illness it slumbers in the body for life: in the nerve ganglia. Decades later it can wake again and then break out as painful shingles (herpes zoster), usually as a belt-shaped rash on one side of the body. For some years there has been a vaccine against chickenpox, and for older people additionally a vaccine against shingles. This allows both forms of this stubborn viral disease to be prevented.
