What is an antibiotic and how do viruses relate to it?

An antibiotic is considered to be a drug that has a detrimental effect on certain viral infections that attack the body. Created using fungi (radiant or moldy) or bacteria. Unlike other similar products, they are not so toxic and are available as an oral intake. Each type of antibiotic has its own area of ​​damage to pathogenic microbes. Their main function is to suppress their reproduction or completely destroy them. For them to give a positive result, there must be a high level of their presence in the blood (for this, the dose of the drug is calculated), otherwise the virus will become resistant to treatment.
