Harmful bacteria cause bacterial infections and can often be treated with antibiotics. Common examples include strep throat and urinary tract infections. Viral infections, on the other hand, are caused by viruses and generally cannot be treated with antibiotics. Examples include the flu, common cold, and COVID-19. While bacterial infections may cause localized symptoms, viral infections can affect the whole body. Diagnosis is key, as treatment for each type differs significantly, often requiring antiviral or supportive care for viruses.
