Antibiotic resistance is a new concern for the medical industry and a modern global health threat. Antibiotics are medicines that treat diseases caused by bacteria not viral infections. So over using or over prescription of antibiotics for conditions such as viral infections and influenza are not only pointless but will lead to the body resisting antibiotics! When the human body resists antibiotic medications you will: Have the infection longer. You may be more likely to have complications of the infection. And you will pass your infection to other people, which increases the problem.
