There are 3 types of skin infections:

Bacterial skin infection

The skin gives a good barrier against bacterial infection. Although many bacteria come into or remain in contact with the skin, they are generally unable to establish infection. When bacteria are infected with the skin, they can range in size from the smallest area to the entire body surface. They can be life-threatening from severe as well as harmless.

Bacterial skin infection develops when bacteria enter through the hair follicles or through small pauses in the skin, which are scrapes, punctures, surgeries, burns, sunburn, animal or insect bites, wounds, And arise from skin disorders. While participating in a wide variety of activities, gardening in contaminated soil or swimming in a contaminated pond, lake, or sea can cause people to develop bacterial skin infections.

Causes of bacterial infection

Many types of bacteria can infect the skin. The most common are Staphylococcus and Streptococcus. Methicillin-resistant Staphylococcus aureus (also known as MRSA), which is resistant to many commonly used antibiotics, is now the most common bacterial infection of the skin in the United States. A particular strain of MRSA has caused more than half of all community-related skin and soft tissue infections treated in the United States. Because MRSA is resistant to many antibiotics, the doctor tailors their treatment based on how often MRSA is found in the local area and whether it is resistant to commonly used antibiotics.


what are its dangers?

Some people are at particular risk of skin infections:

  • People with diabetes, who are prone to blood loss (especially in the hands and feet), have high levels of glucose in their blood (glucose), which reduces their ability to fight infections.
  • People who are hospitalized or living in nursing homes
  • People who are old
  • People who have human immunodeficiency virus (HIV), AIDS or other immune disorder or hepatitis
  • People who are undergoing chemotherapy or are treated with other drugs that suppress the immune system
Skin that is inflamed or damaged is more likely to be infected. In fact, any rupture in the skin makes a person susceptible to infection.


Cleaning the skin with soap and water

To prevent bacterial skin infection, it is important to keep the skin spotless and clean. When the skin is cut or scratched, the bruise should be washed with soap and water and covered with a sterile bandage.

Keeping tissue moist and bacterial Petrolatum can be applied in open areas to try to prevent the invasion of mice. Doctors advise every people not to use any antibiotic ointment (prescription or nonprescription) on minor wounds due to the risk of developing allergies to antibiotics.

  • Drainage of abscesses

The residue should be cut open by a doctor and allowed to drain, and any dead tissue should be surgically removed.

Fungal Skin Infection

Fungi usually make their homes in moist areas of the body where the surface of the skin is found: between the toes, in the genital area, and under the breasts. Common fungal skin infections are caused by yeast or dermatophytes, such as epidermophytan, Microsporum, and trichophyton. Many such fungi live only in the uppermost layer of the epidermis and do not penetrate deep. Obese people are more likely to get these infections because they have excessive skinfolds, especially if the skin within the skin becomes irritable and breaks. People with diabetes are more prone to develop fungal infections.

Oddly, fungal infections on one part of the body can cause infections in other parts of the body that are not infected. For example, a fungal infection on the feet can cause an itchy, bumpy rash on the fingers. These eruptions are allergic reactions to the fungus. They do not result with touching the infected area.
