- The main symptoms are red, itchy bumps on the epidermis.
- Symptoms usually start 10-21 days after being infected with the virus.
- Bumps dry up 8-10 days later (no longer contagious), form a scab which falls off 1-2 weeks later with little/no scarring.
- Bumps start to appear on head, arms,and legs, but mostly on the torso.
- Progresses to all parts of the body over the next few days.
Other symptoms are:
- Headache:
Usually only during the contagious stage of the virus (when bumps are still red).
- Nausea:
In the early stages of contagiousness.
- Myalgia (Muscle Pain).
- Anorexia:
Will not occur in most cases but has been linked to Chicken Pox.
- Malaise:
General Discomfort or Feeling Different than usual.
- Fever:
Anywhere from 38C-42C or 100F-108F (degrees).
Incubation period
- 1 to 5 days prior to symptoms it is contagious.
- It is also contagious until ALL blisters are dried and have formed scabs.
Major Complications:
- May cause Pneumonia (inflammatory condition of the lung) & encephalitis (acute inflammation of the brain).
Possible Complications for Pregnant Women or Newborn Children:
-Skin Disorders.
-Damage to Cervix & Spinal Cord.

was deviated from the Oka Strain
- Washing hands daily.

Treatments:
Natural:
- Pea Water w/ vinegar
- Baking Soda
- Vitamin E Oil
- Honey
- Herbal Tea
- Carrot and Coriander
- Stay away from heat and sweat as it makes symptoms more irritating
Non-natural:

Miscellaneous:
( Historical background if pertinent. Any unusual or interesting info? )
-Chicken pox has nothing to do with chickens, but there are several interesting ideas about how the name originated:
The blisters caused by chicken pox were once thought to look like chick peas, because of their similar size.
The rash looks like peck marks from a chicken.
Chicken pox was just a "wimpier version" of smallpox so they called it "chicken" pox.
