Impetigo is a common, highly contagious bacterial skin infection that typically affects children, though adults can also be affected. It is primarily caused by two types of bacteria, Staphylococcus aureus and Streptococcus pyogenes. The bacteria can invade the skin through a small cut, insect bite, or even an area of eczema, making these areas more susceptible to the infection. Impetigo presents as red sores or blisters that quickly rupture, ooze for a few days and then form a yellowish-brown crust. These sores primarily occur around the nose and mouth but can spread to other parts of the body through touch or use of contaminated objects. The progression of impetigo usually takes a few weeks without treatment, but with appropriate care, symptoms can resolve in a much shorter timeframe. Although impetigo causes uncomfortable sores, it usually doesn't lead to any long-term skin damage or scarring.
