Doctors do not prescribe antibiotics for viral infections because antibiotics are only effective against bacterial infections. Viral infections are caused by viruses, which behave differently from bacteria and do not respond to antibiotic treatment. Using antibiotics for viral infections can contribute to the development of antibiotic resistance, as the overuse of antibiotics can lead to bacteria becoming resistant to the drugs. Therefore, it is important for doctors to accurately diagnose the cause of an infection before prescribing treatment in order to provide the most effective care for the patient.
