Antibiotics are useful and effective medications when used to treat bacterial infections. They have absolutely no value in the treatment of viral infections and do not work. What's more, they may cause significant and nasty side effects. Good pediatricians do not prescribe antibiotic for viral infections.
Viruses are very simple creatures.
Viruses are very good at this and multiply in the body very rapidly. They invade and take over our normal cells and force them to help in the viral reproduction. This causes all of our symptoms because their reproduction kills the host cells. Kids get so many viruses simply because there are so many viruses to get. There are more than 100 varieties of rhinovirus, the agent that causes the common cold.
