How Does Chickenpox Look in Adults?

Adults with chickenpox develop a rash that turns into as many as 250 to 500 blisters, notes the National Foundation for Infectious Diseases. Body aches, itching, fever, fatigue and irritability are other symptoms of chickenpox.

The rash associated with chickenpox in adults usually lasts between five and seven days and may spread into the mouth or other internal parts of the body, states the National Foundation for Infectious Diseases. Chickenpox is highly contagious. The chickenpox virus stays in the body and may become active later in life and cause shingles. People display the symptoms of chicken pox between 10 and 21 days after exposure to the virus. Chickenpox is not normally a serious condition, though the risk of hospitalization or death is higher for adults and adolescents.

The best way to prevent chickenpox is through vaccination against the disease, notes the National Foundation for Infectious Diseases. People who receive the chickenpox vaccination rarely develop the disease, and those who do generally have a mild form with less than 50 red bumps that rarely turn into blisters. Health care workers, college students, teachers, day care workers and international travellers are some of the people at higher risk of contracting chickenpox. While the chickenpox vaccine has potential side effects, the risks associated with contracting chickenpox are higher.
