Bacterial infections often cause localized symptoms that differ from viral illnesses. Common signs include persistent fever, chills, and fatigue. Redness, warmth, swelling, and pain at a specific site may indicate a skin or soft tissue infection. Pus or thick discharge, especially from wounds, eyes, or the throat, is another hallmark. Respiratory infections may produce green or yellow mucus and a worsening cough. Urinary tract infections can cause burning during urination and cloudy urine. Swollen lymph nodes and symptoms lasting longer than a few days also suggest bacterial involvement. Treatment may involve antibiotics such as cephalexin capsules wholesale supplied to pharmacies and healthcare providers.
