Chickenpox is common and mostly affects children, although you can get it at any age. It usually gets better by itself within a week without needing to see a GP.
Good levels of personal hygiene can reduce the risk of spreading the infection. Covering the nose and mouth when sneezing and coughing, preferably with a tissue which can then be disposed of, and regular hand-washing.
Unfortunately there is no cure for chicken pox and most of cases resolve without any specific treatment. Soothing Lotions and gels can be purchased over the counter to reduce itching. However Ibuprofen should not be given to relieve discomfort as it can make someone with chickenpox very ill instead paracetamol can be given instead. Anyone infected should stay away from school, nursery or work until all blisters have scabbed over, when the virus is no longer infectious
