The typical symptom of chicken pox is a red itchy skin rash that can spread to almost everywhere on the body.
First signs of chicken pox that may appear include:
- headache, painful muscles
Chicken pox is a very contagious disease caused by the varicella-zoster virus. The virus is spread:
- In the air when an infected person coughs or sneezes. You can become infected by breathing in these droplets from the air or by handling a surface or object that these droplets have landed on
Chicken pox is normally a mild disease. But serious complications can arise, especially in high-risk people. The most common complication of chicken pox is secondary bacterial infection of the chicken pox lesions, which should be treated with antibiotics.
A vaccinated person is likely to have a milder case of chicken pox if infected. Protection from one dose is not lifelong and a second dose is necessary five years after the initial immunization.
The chicken pox vaccine is made from a small amount of weakened live varicella zoster virus.
