का कारण बनता है

Impetigo is caused by bacteria. The most common type of bacteria associated with this infection include:

  • Group A स्ट्रैपटोकोकस
  • Staphylococcus

These types of bacteria are normally found on the skin and in the nose. The bacteria does not cause trouble until it gets under the skin. Bacteria gets in under the skin through small cuts, scratches, or insect bites.

जोखिम कारक

Factors that increase your chance for impetigo include:

  • Age: most impetigo occurs in preschool and school-aged children
  • Touching a person with impetigo
  • Touching the clothing, towels, sheets, or other personal items that belong to a person with impetigo
  • Poor hygiene, particularly unwashed hands and dirty fingernails
  • Crowded settings where there is direct person-to-person contact, such as schools and the military
  • Contact sports such as football and wrestling
  • Warm, humid environment
  • Summer season
  • Poor health or weakened immune system
  • Tendency to have skin problems such as eczema, poison ivy, or skin allergy
  • Cuts, scratches, insect bites, or other injury to the skin
  • छोटी माता
  • Lice infections which cause scratching (like scabies, head lice, or public lice)

लक्षण

Symptoms of impetigo appear 4-10 days after contact with the bacteria.

The main signs of impetigo are skin lesions. They occur most often on the face, arms, or legs but can appear anywhere on the body. The lesions may be red spots, sores, or blisters. The lesion may:

  • Ooze and become covered with a flat, dry, honey-colored crust
  • Itch
  • Increase in size
  • Spread, especially if scratched

There may also be swollen lymph nodes in the area with more serious infections.Impetigo is normally a fairly mild condition. However, further problems could develop if it is not treated. The infection could spread. This can lead to pain, swelling, pus, or fever. Rarely, impetigo that is caused by Group A स्ट्रैपटोकोकस may develop into:

  • Glomerulonephritis —damage to part of the kidney
  • Scarlet fever—illness that may include a fever, sore throat, and widespread rash
  • Life-threatening invasive streptococcal disease

निदान

Your doctor will ask about your symptoms and medical history. The skin lesions will be examined. Your doctor will be able to diagnose impetigo by the look of your skin lesions.

Your doctor may test a sample of the infected skin. This will show what specific bacteria are causing the infection. It may help to guide treatment choices.

उपचार

The goals of treatment are to relieve the symptoms and cure the infection.

उपचार में शामिल हो सकते हैं:

एंटीबायोटिक दवाओं

Antibiotics are a type of medicine that can fight bacteria. For a mild infection your doctor may recommend:

  • Prescription topical antibiotic (eg mupirocin , retapamulin )
  • Over-the-counter topical antibiotic such as neomycin, bacitracin , or polymyxin—may be significantly less effective
  • Topical antibiotics for the inside of the nose—bacteria can hide in the nose and make it easy for the infection to return

Your doctor may prescribe oral antibiotics, such as:

  • Cephalosporin
  • A penicillin

In some cases, staphylococcal infections (such as MRSA) may be resistant to these antibiotics. Others options may be needed.

त्वचा की देखभाल

Good skin care is important with this type of infection. It can help prevent the spread of the infection to other areas of your skin or to others. In general:

  • Do not touch or scratch the lesions.
  • Wash the skin several times a day. Use soap and water or an antibiotic soap.
  • The crusts may be removed by soaking the infected area. Place warm water on the area for about 15 minutes.
  • Lesions should be covered loosely with gauze, a bandage, or clothing.

Avoiding Spread of the Infection

To help avoid spreading the infection:

  • Wash your hands often and thoroughly. Make sure you wash under your fingernails where bacteria can hide. It is important to wash your hands after touching an infected area of your body.
  • Avoid contact with newborn babies.
  • Stay home until you have had treatment for 24 hours.
  • Do not handle food at home until you have had treatment for at least 24 hours.
  • If you work in the food service industry, ask your doctor when it is safe for you to return to work.
