Impetigo

Impetigo: Description, Causes and Risk Factors:ImpetigoA contagious superficial pyoderma caused by Staphylococcus aureus and/or group A streptococci (Group A beta-hemolytic streptococcal (GABS)).Types impetigo: Bockhart , bullous of newborn, follicular, bullosa,  circinata, impetigo contagiosa, contagiosa bullosa, herpetiformis, neonatorum,  vulgaris.The skin normally has many types of bacteria on it, but intact skin is an effective barrier that keeps bacteria from entering and growing in the body. When there is a break in the skin, bacteria can enter the body and grow there, causing inflammation and infection. It is caused by streptococcus (strep) or staphylococcus (staph) bacteria. Methicillin-resistant staph aureus (MRSA) is becoming a common cause.Impetigo may results from:Insect bites.
  • Animal bites.
  • Human bites.
  • Injury or trauma to the skin.
Impetigo may develop after the skin is infected with GABS. The bacterium is usually acquired from skin-to-skin contact with another person with impetigo. Less commonly, impetigo may develop when open skin lesions (such as insect bites or burns) are infected following exposure to a person with streptococcal pharyngitis ("strep throat").It is most common in children, particularly those in unhealthy living conditions.In adults, it may follow other skin disorders or a recent upper respiratory infection such as a cold or other virus. It is similar to cellulitis, but it only involves the top layers of the skin.Symptoms:Impetigo begins as a cluster of small blisters that expand and rupture within the first 24 hours. Thethin yellow fluid that drains from the ruptured blisters quickly dries forming a honey-colored crust.It develops most frequently on the legs, but may also be found on the arms, face and trunk.There is usually no fever.Diagnosis:Diagnosis is based mainly on the appearance of the skin lesion.A culture of the skin or lesion usually grows the bacteria streptococcus or staphylococcus. The culture can help determine if MRSA is the cause, because specific antibiotics are used to treat this infection.Treatment:A mild infection may be treated with a prescription antibacterial cream. More severe cases may require antibiotics, taken by mouth. Wash the skin several times a day, preferably with an antibacterial soap, to remove crusts and drainage.Preventive Measures:Do not share personal things.
  • Wash cuts and scrapes well.
  • Avoid scratching, skin irritation, insect bites or scratch.
  • Maintaining of good hygiene practices help to a great extent in preventing impetigo.
