Chickenpox or varicella is a highly contagious viral disease. It's caused by the varicella-zoster virus (VZV) An
infected person is contagious for one to two days (possibly five days) before
the onset of the rash and remains infectious until the blisters form scabs
(usually around day five of the illness).
The main symptom is a
blistering skin rash. Outbreaks are more common in winter and early spring.
Children and adults can be immunised against chickenpox. Children
with chickenpox should not go to school, kindergarten or creche until the last
blister has dried.
For most healthy people, chickenpox is mild and the person recovers fully without specific treatment. Complications do occur in approximately one per cent of cases. Chickenpox is more severe in adults and in anyone (of any age) with impaired immunity. Immunisation is the best way to prevent chickenpox. Depending on how severe it is, there are small possibilities of dieing.
