14 Causes of Impetigo

2. Insect Bite

Some insects can carry the bacteria that cause impetigo. Their bites even though small, can open up the skin and allow the bacteria to infect the body. Most insect bites itch, and when scratched, the skin is broken, which can also allow the bacteria to spread or enter the body. Anytime the skin is open and exposed; the body is vulnerable to bacterial infections.

If the insect bite only goes into the first layer of skin, the bacteria may only be present in a small area on the surface of the skin. The bacteria can come from almost anywhere, and children and adults may have it on their hands or under their nails. When they scratch or pick at the skin, the bacteria can travel from the hands or nails to the skin, and infect it. If you have an insect bite, it’s important to treat it with antibiotic cream and avoid scratching or picking at it.
