A bacterial infection is an infection caused by bacteria. Bacteria are single-celled organisms that can cause disease in humans and other animals. Bacterial infections can be mild or severe, depending on the type of bacteria causing the infection. Common symptoms of a bacterial infection include fever, chills, coughing, vomiting, diarrhea, and fatigue. Treatment for bacterial infections usually involves antibiotics.
