Impetigo is a contagious bacterial skin infection. It can easily spread to other parts of the body or other people. It stops becoming contagious 48 hours after you start treatment or when the patches dry out.
Impetigo can either affect healthy skin or broken skin. It, however, most commonly affects broken skin. The most common bacteria responsible include Staphylococcus and Streptococcus. Keep abrasions, cuts and insect bites clean to help avoid an infection. It usually takes 4-10 days for the rash to appear after you have been infected with the bacteria. It usually starts with blisters or red sores. These then usually become crusty patches of skin which can spread and increase in size.
An antibiotic cream such as Fusidic Acid is commonly used to treat the condition. We may prescribe Fusidic Acid if clinically appropriate:
