When certain bacteria enter our body, they can create bacterial infections. It is important to seek treatment for bacterial infections quickly to stop the growth of the bacteria and kill the present bacteria.

What Are the Symptoms of Bacterial Infections?

The symptoms can vary depending on the type of infection, location, and person to person. Below are some of the most common symptoms of bacterial infections:

  • Pain
  • Swelling
  • Redness
  • Boils or abscesses
  • Fever
  • Fatigue
  • Chills

Types of Bacterial Infections in the Skin 

There are bacterial infections that can infect all different areas of the body. Below are some common skin-related bacterial infections.


Cellulitis is a common bacterial infection. It causes the skin to get red and swollen. Cellulitis can be painful, and affected skin will often feel tender and hot to the touch. While it is treatable, it can become serious. Cellulitis spreads quickly, and if left untreated for too long, the bacteria can spread to the bloodstream and lymph nodes. It can affect any area of the skin but is regularly found in the lower legs.


Impetigo is a contagious bacterial infection. It can occur in people of any age but commonly affects children. The bacteria enter from a break in the skin. This can be from a cut, insect bite, or scratch. Impetigo creates red sores throughout the skin, which then form into blisters and bursts. After this, a yellow crust can form. The sore may also be itchy or painful, but the symptoms can vary.

Treatment for Bacterial Infections

Many bacterial infections require oral antibiotics. For some less severe cases, there may be the option of topical antibiotic cream or ointments. The healing process with antibiotics usually takes between one and two weeks.
