Impetigo is a common bacterial skin infection usually caused by "staph" (Staphylococcus) or "strep" (Streptococcus) bacteria. Impetigo often starts with a cut or break in the skin that allows bacteria entry.
Superficial bacterial skin infection.
Impetigo accounts for approximately 10% of skin problems observed in pediatric clinics. It occurs more frequently in a warm humid environment, in tropical climates and lower altitudes. The prevalence of impetigo varies seasonally; however, in regions that remain warm and humid throughout the year, seasonality may not occur.
Warm humid conditions combined with frequent cutaneous disruption via biting insects favor its development throughout the year in tropical climates. Geographic regions that have crowded conditions or poor hygiene also have increased prevalence of impetigo.
Impetigo is found most commonly in preschool-aged children. Rapid dissemination can occur through daycare centers, nurseries, and grade schools.
