Differentiating viral and bacterial infections involves clinical evaluation and diagnostics. Bacterial infections, often treatable with antibiotics like cephalexin supplier, may present with localized symptoms, high fever, and pus. Viral infections typically cause widespread symptoms like fatigue, body aches, and runny nose, and antibiotics are ineffective. Doctors use tests like blood counts, cultures, or rapid antigen tests to confirm the cause. For instance, a high white blood cell count suggests bacterial infection, while viruses may lower it. Accurate diagnosis ensures proper treatment, avoiding unnecessary antibiotic use, which can lead to resistance. Always consult a healthcare professional.
