How do you get Impetigo? Impetigo is caused by bacteria-strep, Staphylococcus aureus or Streptococcus pyogenes that infects the skin through a break, like a cut, insect bite, or bodily injury. It can also show up in perfectly healthy skin. What are the symptoms of Impetigo? You may notice red spots turning into blisters that break and feel itchy. You may have a sore that leaks fluid and appears to be crusty.
The sore can increase in size as big as a coin or small like a pimple. As with Cellulitis, antibiotics can shorten an Impetigo infection and keep it from spreading to others. Should you find yourself with any of these contagious symptoms, please contact the Dermatology Center in Orem, Utah to see one of our skilled dermatologists. Kraig K.

Impetigo is a common and contagious skin infection. Bacteria like Staphylococcus aureus or Streptococcus pyogenes infect the outer layers of skin, called the epidermis. The face, arms, and legs are most often affected. The infection often begins in minor cuts, insect bites , or a rash such as eczema — any place where the skin is broken.
But it can also occur on healthy skin. Impetigo is an old disease. Bacteria thrive in hot, moist conditions. So impetigo tends to be seasonal, peaking in the summer and fall in northern climates. In warm and humid climates, it tends to occur year-round. An estimated million children worldwide have impetigo at any one time.
Impetigo is more common in developing countries and in poor areas of industrial countries. The highest numbers of cases are in areas like Oceania, which includes Australia, New Zealand, and several other countries. Impetigo is an infection caused by strains of staph or strep bacteria. These bacteria can get into your body through a break in the skin from a cut, scratch, insect bite, or rash. Then they can invade and colonize.
The condition can be contagious. You can catch these bacteria if you touch the sores of a person with impetigo or you touch items like towels, clothes, or sheets that the person used. Some people normally carry staph bacteria on the inside of their nose. They may get infected if the bacteria spreads to their skin. The first signs of impetigo are reddish sores on the skin, often clustered around the nose and lips. These sores quickly grow into blisters, ooze and burst, and then form a yellowish crust.
The clusters of blisters may expand to cover more of the skin. Sometimes the red spots just develop a yellowish crust without any blisters being seen. The sores can be itchy and occasionally painful. After the crust phase, they form red marks that fade without leaving scars. Infants sometimes have a less common type of impetigo, with larger blisters around the diaper area or in skin folds.
These fluid-filled blisters soon burst, leaving a scaly rim called a collarette. Impetigo can be uncomfortable. Occasionally, it may involve swollen glands in the area of the outbreak or a fever. Your doctor can usually diagnose the infection by its appearance. This involves taking a little bit of the liquid that comes out of the sore and testing it to see what type of bacteria caused it to determine which antibiotics will work best against it.
Antibiotics are effective against impetigo. Which type of antibiotic you get depends on how widespread or severe the blisters are. If you have impetigo in only a small area of your skin, topical antibiotics are the preferred treatment.
Options include mupirocin cream or ointment Bactroban or Centany and retapamulin ointment Altabax. With treatment, impetigo usually heals in 7 to 10 days. It is a contagious disease which is more frequent in patients with poor hygiene.
It can be treated by general antibiotics, mainly macrolides, penicillin M or cephalosporins.
