Causes of bacterial infections can include exposure to contaminated water or food, weakened immune systems due to age or illness, skin abrasions or cuts that provide entry points for bacteria, and contact with infected people or animals. Symptoms of a bacterial infection may include fever, chills, fatigue, coughing, sore throat, headache, nausea, vomiting, diarrhea, and redness around the affected area. In more serious cases, bacterial infections can cause pneumonia, meningitis, urinary tract infections, and bloodstream infections.
