Can you get impetigo from scratching yellow fly bites?

Yes, scratching yellow fly bites can increase the risk of developing impetigo, as it can introduce bacteria from the skin or the environment into open wounds. Impetigo is a contagious skin infection often caused by Staphylococcus or Streptococcus bacteria. To minimize the risk, it's important to avoid scratching bites and to keep the affected area clean and covered. If signs of infection develop, such as redness, swelling, or oozing, seeking medical attention is advisable.
