Why don t antibiotics work on viruses?
Viruses don’t have cell walls that can be attacked by antibiotics; instead they are surrounded by a protective protein coat. Unlike bacteria, which attack your body’s cells from the outside, viruses actually move into, live in and make copies of themselves in your body’s cells.
Is it bad to take antibiotics with a virus?
Antibiotics do not work on viruses, such as those that cause colds, flu, bronchitis, or runny noses, even if the mucus is thick, yellow, or green. Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics.
In complicated or prolonged viral infections, bacteria may invade as well, and cause what is known as a “secondary bacterial infection ”. In these cases, your doctor may prescribe an antibiotic, if one is needed, to kill the specific invading bacteria.

But the treatment of viral infections has proved more challenging, primarily because viruses are relatively tiny and reproduce inside cells. For some viral diseases, such as herpes simplex virus infections, HIV/AIDS, and influenza, antiviral medications have become available.
Which diseases Cannot be cured by antibiotics?
Antibiotics can only treat illnesses caused by bacteria. Colds, the flu, most sore throats, bronchitis, and many sinus and ear infections are caused by viruses, not bacteria. If your child has a viral infection, for example, antibiotics won’t help them feel better or get well sooner.
