If you wonder why most people think antibiotics can treat viral diseases, one reason is that when people use search engines to understand what antibiotics do, they are informed that antibiotics do target viruses. Examples below.
antibiotic: a medicine (such as penicillin or its derivatives) that inhibits the growth of or destroys microorganisms.
microorganism: a microscopic organism, especially a bacterium, virus, or fungus.
antibiotic: any of a large group of chemical substances, as penicillin or streptomycin, produced by various microorganisms and fungi, having the capacity in dilute solutions to inhibit the growth of or to destroy bacteria and other microorganisms, used chiefly in the treatment of infectious diseases.
microorganism: any organism too small to be viewed by the unaided eye, as bacteria,protozoa, and some fungi and algae.
antibiotic: a substance produced by or a semisynthetic substance derived from a microorganism and able in dilute solution to inhibit or kill another microorganism.
microorganism: an extremely small living thing that can only be seen with a microscope.
antibiotic: A substance, such as penicillin or erythromycin, produced by or derived from certain microorganisms, including fungi and bacteria, that can destroy or inhibit the growth of other microorganisms, especially bacteria. Antibiotics are widely used in the prevention and treatment of infectious diseases.
microorganism: any organism, such as a bacterium, protozoan, or virus, of microscopic size.
antibiotic: chemical substance produced by a living organism, generally a microorganism, that is detrimental to other microorganisms. Antibiotics commonly are produced by soil microorganisms and probably represent a means by which organisms in a complex environment, such as soil, control the growth of competing microorganisms.
microorganisms: living things that are too small to be seen with the naked eye. They are normally viewed using a microscope. Bacteria, viruses, and some molds are examples of microorganisms.
antibiotic: Any substance that can destroy or inhibit the growth of bacteria and similar microorganisms.
microorganism: An organism that is too small to be seen by the unaided eye, especially a single-celled organism, such as a bacterium.
