Treatments for impetigo include antibiotic creams, and in some cases, it will clear up on its own. However, be careful because impetigo is contagious for 48 hours.
Once sores have healed and dried up, they can no longer be spread to others.
Usually impetigo can get better on its own. If there are complications, it can usually spread to the lymph nodes (called lymphadenitis) or to a deeper layer of the skin.
The two types of impetigo are:
• non-bullous impetigo - which is more contagious than bullous impetigo and causes sores that quickly rupture (burst) to leave a yellow-brown crust
Impetigo can also be classed as:
• primary - where bacteria enters skin through a cut or wound. This occurs in skin which is, aside from that wound health.
• secondary – this is when the impetigo infection results from a skin condition.
