Chickenpox is a highly infectious disease caused by the varicella zoster virus. It is a childhood disease that sometimes affects adults and causes itchy skin blisters.

Chickenpox is caused by Herpes Zoster Virus that is transmitted through the air or by direct contact with broken chickenpox blisters of an infected person.


  • Slight fever
  • General feeling of illness
  • Headache
  • Small red spots initially on the scalp, neck, or upper half of the body, then all over
  • About twelve to twenty-four hours later, these spots become itchy and develop into fluid-filled blisters.

Since chickenpox is caused by a virus, antibiotics are ineffective. It is not a dangerous disease and it gets cured on its own. Cool baths and calamine lotion can help reduce itchiness. Scratching should be avoided and blisters should be kept clean.

Treatment is usually given to control fever and discomfort. Antibiotics are used if the blisters get infected. Genital blisters can be treated with a pain killing cream.

For adults or children with weak immune systems, anti virus medicines can be used. 

It can be prevented through vaccination between 12 to 15 months of age followed by a booster shot between 4 to 6 years of age.
