Detailed explanation-1: -Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics. We rely on antibiotics to treat serious, life-threatening conditions such as pneumonia and sepsis, the body’s extreme response to an infection.

Detailed explanation-2: -Antibiotics are used to treat or prevent some types of bacterial infection. They kill bacteria or prevent them from reproducing and spreading. Antibiotics aren’t effective against viral infections. This includes the common cold, flu, most coughs and sore throats.

Detailed explanation-3: -Each time you take an antibiotic, bacteria are killed. Sometimes, bacteria causing infections are already resistant to prescribed antibiotics. Bacteria may also become resistant during treatment of an infection.

Detailed explanation-4: -Antibiotics will kill most bacteria, including the helpful bacteria in our body. But the bacteria with the advantages can survive and reproduce. The resistant bacteria can pass the DNA changes on to their offspring, or sometimes even to each other, to generate new strains of antibiotic resistant bacteria.
