Impetigo

Impetigo is an infectious bacterial infection of the skin. It is characterized by presence of pus-filled bumps that may drain forming a crust. It may heal spontaneously within few weeks without leaving behind any scar.

Predisposing factors

There are many factors that make one more susceptible to catch infection and have impetigo. These factors are usually related to poor skin health and weak immunity. The risk factors for impetigo include malnutrition which affects both skin health and general body immunity. Overcrowding and poor hygiene, which are the key for spread of any infectious problems. In addition, skin diseases such as scabies and pediculosis play great role in making the skin vulnerable for infection.

Symptoms

The symptoms of impetigo are mainly the presence of pus-filled bumps that rapidly rupture forming yellowish brown crusts. When the crust dries up and separates, it leaves behind a red area of skin which fades later without ending in any scar.

Impetigo, as an infection, may be also accompanied with fever and swelling of the lymph nodes near the area of skin affected.

Impetigo usually affects the face and the scalp. However, it may affect any other part of the skin except the palm of hand and the sole of foot.

Treatment

In many cases, impetigo heals on its own within two or three weeks. However, the healing process could be facilitated by the use of certain drugs. Crusts can be dissolved and removed by using olive oil. Also, septic lotions such as k. permanganate (Chameleon mineral) and topical anti-biotic such as Na-fusidate (Fucidin) are recommended to fight the infection.

In severe cases, it is recommended to take a systemic anti-biotic regimen such as erythromycin (Erythrocin) for at least 7 days to help eliminate the infection.
