Chickenpox is a highly contagious childhood infection caused by the varicella zoster virus. The condition causes a very itchy, blistery rash and usually a fever. The chickenpox virus spreads through the air, such as when an infected person sneezes or coughs, and by direct contact. Chickenpox once was very common, but the number of those infected has significantly dropped since the development of a vaccine to prevent the infection. Being exposed to the chickenpox virus also raises your risk for a painful condition called shingles later in life.

Picture of the Chickenpox Rash
Varicella Chickenpox. Varicella Chickenpox is caused by a virus of the herpes group. The disease is highly contagious and is spread by droplet or direct contact. The incubation period for chickenpox ranges from 11 to 21 days. Prodromal symptoms consist of low-grade fever, headache, anorexia, and malaise. On the following day, the characteristic rash begins to appear. The lesions evolve from erythematous macules to form small papules. Quickly, a clear vesicle arises on this erythematous base. The classic lesion of chickenpox has been poetically described as a “dewdrop on a rose petal.” Over the next several days, the vesicles rupture and then crust. The rash begins on the chest and back and spreads centrifugally to involve the face, scalp, and the extremities. New lesions of chickenpox arise in crops over a period of several days.
