What Causes an Impetigo Rash?


It is a very common occurrence for someone to develop an impetigo rash due to an infection. This type of skin infection is caused by a very common form of bacteria that most people can easily come into contact with in everyday life. An impetigo rash and infection is very contagious but is also relatively easy to treat with a doctor’s help.


While impetigo can affect just about anyone, it is commonly seen in children. The forms of bacteria responsible for the development of impetigo are Staphylococcus and Streptococcus bacteria. These are fairly common forms of bacteria that can cause many types of infection in humans. The presence of the MRSA or drug resistant staph aureus bacteria today is another common cause of impetigo. These forms of bacteria can enter the human body through breaks in the skin or sometimes without any sign of skin disturbance. When any of these types of bacteria are allowed to enter the skin and grow uncontrolled, then an impetigo infection can occur. This is this reason why this type of infection is often seen in children who live in unhealthy environments or do not practice hygiene regularly. Other conditions may also lead to the development of bacterial infections. These may include other forms of skin problems or conditions and upper respiratory infections.


An impetigo rash can develop if the blisters or small spots that form are scratched and the infection is allowed to spread to other areas of the body. Other impetigo symptoms include pus filled blisters that can be extremely itchy and oozy, inflamed lymph nodes and lesions. These symptoms can affect many parts of the body including the face, buttocks, arms, legs, and parts of the torso. Fluid and pus that comes from blisters or rashes caused by impetigo carry the bacteria. This is why impetigo infections are contagious. It is important not to scratch the infection and then come into contact with other people as the infection can easily be spread in this manner. This is another reason why the infection is so prevalent in children, as it is often extremely hard to control their contact with one another.


Impetigo is usually pretty easy to diagnose. The lesions, blisters and rashes that develop on the skin due to impetigo are easy to identify. A culture may be required to rule out the possibility of MRSA bacteria, because a doctor will be required to prescribe specific medications if this type of bacteria is the cause. Overall, this kind of infection is easy to cure. Sometimes it may reoccur after treatment, which is seen especially in children. Treatment for impetigo often involves a prescription strength anti-bacterial topical medication. This will usually get the job done, but serious cases may require oral anti-bacterial medication as well.


Keeping the healing infection clean is the next important step of treatment. Using antibacterial soap on the rash is best to reduce the risk of spreading the infection and to prevent the bacteria from reoccurring. It is also important to keep patients with the infection away from other people and quarantine the clothing and towels that they use. The bacteria may be spread through infected fabric and clothing as well as other personal hygiene products. During treatment, it is best to use a fresh and clean towel when cleaning the lesions, blisters and rash to prevent spreading more bacteria. Because this type of infection is spread by bacteria, maintaining a healthy and hygienic lifestyle is the best prevention. Always clean wounds or cuts, wash your hands thoroughly and often and avoid contact with anyone who is showing signs of impetigo such as blisters or a rash.
