Why antibiotic should not be overused prepare a short report?

When they're actually used correctly, antibiotics can do an amazing job of clearing up the most lethal bacterial infections. And if you're sick enough to be hospitalized for an infectious illness like pneumonia, those antibiotics might even save your life.

But like most drugs today, antibiotics are overused and over- prescribed-despite repeated pleas from infectious disease experts warning otherwise. Their crystal clear usage guidelines are often ignored by busy doctors eager to appease the many patients who show up demanding a quick fix for their colds and sore throats.

One of the most serious problems with antibiotic overuse is that too many strains of bacteria are becoming resistant to the drugs. Infectious bacteria constantly multiply. All it takes are a few strong bacteria to actually defeat the antibiotic. And the constant fight against antibiotics teaches the bacteria to grow even stronger, making them much harder to kill. This not only creates the need for more antibiotics, but it can also be life-threatening if the right antibiotic isn't found in time.

The huge problem with all of this is that most common upper respiratory tract infections and sore throats are caused by viruses --not by bacteria. Antibiotics are useless in these cases--and they still promote resistant bacteria, jeopardizing your health without any clear benefit.
