Impetigo is a prevalent type of skin infection brought about by the Staphylococcus aureus bacteria. This condition typically affects children 2-6 years of age but older children and even adults can acquire it.
What are the signs?
It is important to note that impetigo is generally mild, but it is highly contagious and can cause the following:
- One or several blisters filled with pus that easily rupture and leave behind raw, reddened skin
- Itchy blisters with yellowish or tan fluid that seeps and forms a crust
- Rash that often spreads
- Enlarged lymph nodes near the site of the infection
- Skin lesions, typically on the nose, lips, arms, ears and legs that can spread to other parts of the body
If brought about by the staph bacteria, the symptoms include reddened skin bordered by reddened blisters that are full of clear fluid or pus that turns cloudy. These blisters readily rupture and leak. When broken, there is a raw, shiny area that scabs over with light yellow to brown crust.
Once an infection arises, it might take up to 3 days before the symptoms manifest. In most cases, the sores are itchy and if scratched, it allows the infection the spread.
Management of impetigo
Impetigo is generally managed with antibiotics either orally or topically. The commonly used topical variants include mupirocin ointment or the oral variants such as clindamycin and cephalosporins.
If an individual is diagnosed with impetigo, some of these tips can help:
- When antibiotics are prescribed, they must be taken as instructed or the infection might recur.
- The skin must be gently washed several times throughout the day with an antibacterial soap to eliminate any crusts and drainage.
- Avoid touching the rash. If accidentally touched, wash hands and the exposed site using water and mild soap.
