Answer by Atheist
They look exactly like mosquito bites, only you get them everywhere and they scab over. They itch like oh holy hell and hurt.
It is a disease, and there is no cure. After the chicken pox are gone, you will always have the infection in your body. The virus can mutate and you can get an advanced form of chicken pox called Shingles. It's a disease that attacks the nerve endings under your skin. Sometimes your skin can flake up like shingles. It's very painful, very very painful. I had a severe case in high school, and it can be caused by stress.

Fat Boi,
The Varicella-zoster virus (VZV) causes chickenpox. The varicella virus is an enveloped, double-stranded DNA virus. It attaches to the wall of the cell it invades, and then enters the cell. The virus uncoats and is transported to the nucleus where the viral DNA replicates creating new virions that are eventually released from the cell to infect other cells. The disease is highly contagious -- over 90% of nonimmune individuals will develop chickenpox following exposure. VZV is communicable by both direct skin-to-skin contact and via respiratory droplets (for example, coughing, sneezing) from the infected individual. While the average incubation period from viral exposure to onset of symptoms is 12-14 days, a broader post-exposure window of 10-21 days is quoted in the literature. The chicken pox rash begins on the trunk and spreads to the face and extremities. The chicken pox lesion starts as a 2-4 mm red papule which develops an irregular outline (rose petal). A thin-walled, clear vesicle (dew drop) develops on top of the area of redness. This "dew drop on a rose petal" lesion is very characteristic for chicken pox. After about 8-12 hours the fluid in the vesicle gets cloudy and the vesicle breaks leaving a crust. The fluid is highly contagious, but once the lesion crusts over, it is not considered contagious. The crust usually falls off after 7 days sometimes leaving a craterlike scar. Although one lesion goes through this complete cycle in about 7 days, another hallmark of chicken pox is the fact that new lesions crop up every day for several days. Therefore, it may take about a week until new lesions stop appearing and existing lesions crust over. Children are not sent back to school until all lesions have crusted over. The vesicles release chemicals in your skin that excite the nerves that make you itch. These nerves in the top layers of your skin tell the brain when something itches. They are the same nerves that get excited when you get a reaction to a mosquito bite. Shingles is caused by the varicella-zoster virus, the same virus that causes chickenpox. After you've had chickenpox, the virus lies inactive (dormant) in your nerves. Years later, the virus may reactivate as shingles. The rash will follow the path of a nerve. It is more common for this to appear on the chest or abdomen. There is no 'cure' for chickenpox or shingles. However, there is treatment and a vaccine to help prevent the disease. The varicella vaccine is a live but weakened form of the chicken pox (varicella-zoster) virus. Most health organizations recommend that children receive a varicella vaccination at 12 to 18 months of age. Adolescents and adults who are not already immune to the chicken pox virus need two doses at least 4 weeks apart. When a weak form of the virus is injected, the body's immune system reacts. It destroys the virus and makes disease-fighting proteins (antibodies) to fight the virus. The antibodies to that virus stay in the body and will keep the person from getting sick or getting severe symptoms if exposed to the virus again. The person is then considered immune to chicken pox. It is not usual for a person to have chickenpox more than once. Thios is because the immune system usually produces antibodies that prevent this. If the immune system is not healthy, then it is possible for chickenpox to occur again.
