Below are seven signs to watch for and other important items to know about skin infections:

1 – Causes

As your body’s largest organ, the skin supports myriad essential functions. One of those functions is to protect your body’s internal organs. It keeps the “bad stuff” (germs) out. When germs enter through breaks, cuts, or wounds in your skin, infections happen. Skin folds that rub together are also at risk, especially if the areas are moist. Infections may also arise in areas with poor blood supply and among individuals with weak immune systems (due to other medical conditions and treatments).

2 – Types 

Infections fall into the following categories, based on the germs associated with them:

• Bacterial – Bacteria cause infections like cellulitis, staph, and impetigo.
  
• Viral – Warts, shingles, and herpes simplex are among those infections caused by viruses.
  
• Fungal – Common infections caused by fungi include athlete’s foot and yeast infections.
  
• Parasitic – Lice, mites, hookworms, and other parasites can infect the skin.

3 – Risk factors 

Certain individuals may be more vulnerable due to poor blood flow, a weak immune system, conditions like diabetes, and prolonged sickness/bed rest. Older people and those who are obese (with excessive skin folds) are also at risk.

4 – Symptoms

Symptoms vary depending on the type of infection, its cause, and personal health factors (such as immune system suppression). Commonly, skin infections manifest as red or dark areas. You may notice flat, raised, wart-like, or bumpy lesions. It’s not uncommon for these areas to feel warm and tender to the touch. When the infection is severe, you may also notice pus, blistering, skin breakdown, and widespread swelling. 

5 – Complications 

In addition to large areas of swelling and inflammation, severe skin infections can cause a high fever and spread beyond the skin, penetrating the tissues underneath. When infections spread to the bloodstream, they can lead to potentially life-threatening sepsis, especially among immunocompromised individuals.

6 – Diagnostics 

To understand your needs, our specialists will perform a physical exam. Be prepared to also discuss any symptoms with one of our providers. Lab tests, such as skin cultures, may be ordered to identify the type of infection. This involves analyzing a sample of tissue that is taken either with a swab, scrape, or biopsy. Sometimes, blood tests may be done. 

7 – Treatment 

Our recommendations are based on factors such as the nature and severity of your infection. While some infections may respond to OTC creams and products, others may require prescription medications such as antibiotics and antivirals for bacterial and viral infections. The specific medication prescribed will depend on the infection’s severity and the risk of complications.
