Doctors do not give antibiotics for viral infections because antibiotics are only effective against bacteria, not viruses. Viral infections do not respond to antibiotics, as they work by targeting the structure or mechanisms specific to bacteria. Over-prescribing antibiotics for viral infections can lead to antibiotic resistance and potential side effects without providing any benefit in fighting the virus. Therefore, healthcare providers typically recommend rest, hydration, and other supportive measures to manage symptoms of viral infections.
