what is the structure of chicken pox?

Varicella (chickenpox)
Description
A disease caused by infection with the varicella zoster virus, which causes fever and an itchy rash
Symptoms
A skin rash of blister-like lesions, covering the body but usually more concentrated on the face, scalp, and trunk. Most, but not all, infected individuals have fever, which develops just before or when the rash appears. If exposed, persons who have been vaccinated against the disease may get a milder illness, with less severe rash (sometimes involving only a few red bumps that look similar to insect bites) and mild or no fever.
Complications
Bacterial infection of the skin, swelling of the brain, and pneumonia. Adolescents and adults are more at risk for severe disease.
Transmission
Spread by coughing and sneezing (highly contagious), by direct contact, and by aerosolization of virus from skin lesions.
Vaccine
Varicella vaccine can prevent this disease. Currently, two doses of vaccine are recommended for children, adolescents, and adults.
