Sources of Chicken Pox Chicken pox is one of the most infectious diseases around; approximately 90% of those who have never had chickenpox or were not vaccinated will become infected when they come into contact with the varicella zoster virus. Chicken pox and colds and flu spread in a similar way. Droplets of water that are expelled from the nose and mouth of the infected person through coughs and sneezes are inhaled by those around them. If the contaminated droplets land on surfaces and objects, they too can become sources of infection if other people touch them. Shingles is a skin rash caused by a nerve and skin inflammation from the same virus that previously caused chickenpox. This virus is called the varicella zoster virus (VZV) and belongs to the herpes family of viruses. After an individual has chickenpox, this virus lives dormant in the nervous system and is never fully cleared from the body. Under certain circumstances, such as emotional stress, immune deficiency (from AIDS or chemotherapy), or with cancer, the virus reactivates and causes shingles. In most cases of shingles, however, a cause for the reactivation of the virus is never found. Anyone who has ever had chickenpox is at risk for the development of shingles, although it occurs most commonly in people over the age of 60. It has been estimated that up to 1,000,000 cases of shingles occur each year in the U.S. Mode of Transmission of Chicken Pox
