Chickenpox (varicella), a viral illness characterised by a very itchy red rash, is one of the most common infectious diseases of childhood. It is usually mild in children but there is a risk of serious complications, such as bacterial pneumonia.
People who have had chickenpox almost always develop lifetime immunity (meaning you are extremely unlikely to get it again). However, the virus remains dormant in the body and it can reactivate later in life and cause shingles.
What causes chickenpox?
Chickenpox is caused by the herpes varicella-zoster virus. It is spread by droplets from a sneeze or cough, or by contact with the clothing, bed linens or oozing blisters of an infected person. The onset of symptoms is 10 to 21 days after exposure. The disease is most contagious a day or two before the rash appears and until the rash is completely dry and scabbed over.
