Impetigo is a highly contagious bacterial skin infection that is caused by streptococcal or staphylococcal bacteria. It is most common in children, but can affect adults as well. The infection typically appears as small blisters or sores on the face, neck, hands, and arms.
Impetigo can be spread through direct contact with an infected person or object or through contact with items an infected person has touched, such as clothing, towels, and toys. It can also be spread through contact with infected animals, such as cats and dogs.
The most common way to treat impetigo is with antibiotics. These may be topical medications applied directly to the skin, or oral medications taken by mouth. Treatment usually lasts about two weeks, and it is important to finish the entire course of antibiotics to prevent the infection from coming back.
If the infection is mild, it can sometimes pass on its own. To help speed up the healing process, it is important to keep the affected area clean and dry. Washing the area with mild soap and water at least twice a day can help reduce the risk of spreading the infection to other parts of the body. Applying a topical antibiotic ointment can also help prevent the spread of the infection.
It is also important to keep the affected area covered with a bandage. This will help protect the area from further infection and help keep the infection from spreading to other people or objects.
In general, impetigo can take anywhere from one to three weeks to fully clear up. If the infection does not improve after two weeks of treatment, it is important to contact a doctor for further evaluation and treatment.
