Impetigo is common among preschool-age children. It begins as a blistery, red, and uncomfortable rash, often accompanied by pimple-like protuberances that are filled with pus. These very often burst and the affected areas then become scabby and itchy.
Two types of bacteria cause impetigo: streptococcus pyogenes (strep) and staphylococcus aureus (staph). The condition is highly contagious.
In preschool-age children, the sores mostly appear under the nose and around the mouth. In general this is not a serious illness, but a passing infection which often clears up on its own within three days. In more serious cases, impetigo is treatable with antibiotics.
Since small children are still developing immunities to infection, they are more likely than older children and adults to contract the infections which may lead to impetigo. Similarly, older children and adults with compromised immune systems would also be at a higher risk for contracting it and certainly for passing it along since it doesn't discriminate when it comes to infecting others.
While many times impetigo is treated with oral antibiotics, it is also common to treat this condition with topical antibiotics, with favorable results. Since there is no "impetigo drug" per se, trying a topical antibiotic may bring great relief and render oral antibiotics unnecessary. In general oral antibiotics are used in more extreme cases.
People with diabetes are at a greater risk of experiencing complications related to impetigo, and certainly if the condition does not clear up on its own or through treatment under a physician's care, further testing may be required to ensure there are no underlying conditions or that there has not been a misdiagnosis.
One of the best things to do if you have impetigo is to keep the area, if at all possible, covered with light gauze to prevent your scratching, infecting it further and causing it to spread. Keeping your fingernails short and limiting contact with others for a few days is also recommended.
