Impetigo is a highly contagious bacterial skin infection, frequently children and infants tend to get it on the face, especially around the nose and mouth, and sometimes on the arms or legs.
The bacterial agent that causes impetigo is the Staphylococcus aureus or it can be the Streptococcus pyogenes.
Complications such as scars, cellulitis and kidney problems can arise from impetigo. Scars are caused by the deeper form of impetigo. Infected skin may also affect the underlying tissues and cause cellulitis. The gravest potential complication of impetigo is post-streptococcal glomerulonephritis, a severe kidney disease that occurs following a streptococcal infection in less than 1% of cases, mainly in children.
Most people get this highly infectious disease through physical contact with someone who has it or from sharing the same clothes, bedding, towels, or other objects. That is why children tend to be infected with impetigo the most.
These are certain factors that may contribute to infection:
- Although any one can have this, it is most common in ages 2 to 6.
- Crowded Conditions.
- Warm, humid weather
- Broken skin
- Poor hygiene
