Signs of a bacterial infection vary by site and severity. Common symptoms include fever, chills, localized redness, warmth, swelling, and pain. Pus, foul discharge, or persistent cough may indicate infection. Gastrointestinal infections can cause diarrhea, nausea, vomiting, and abdominal cramps. Urinary infections often present with burning urination and urgency. Systemic infections may trigger fatigue, body aches, rapid heart rate, or confusion. Symptoms that worsen, spread, or fail to improve warrant medical evaluation. Appropriate antibiotics are prescribed based on diagnosis; access through regulated channels, including cephalexin capsules wholesale distribution, supports timely treatment while emphasizing responsible use and antimicrobial stewardship practices globally.
