What infections should not be treated with antibiotics?

Antibiotics should not be used to treat viral infections. Antibiotics are only effective against bacterial infections. Where the confusion can lie is that antibiotics have no use against viral pathogens and viral illnesses. A lot of the common illnesses that people get that cause sore throats, ear pain, and coughs, wind up being caused by viruses. These illnesses will not be affected by antibiotics. Taking antibiotics in that scenario can cause some unintended consequences that a lot of people don't realize.
