Detailed explanation-1: -Summary. Many human illnesses are caused by infection with either bacteria or viruses. Most bacterial diseases can be treated with antibiotics, although antibiotic-resistant strains are starting to emerge.

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: -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-4: -Antibiotic resistance occurs when bacteria change so that antibiotic medicines can’t kill them or stop their growth. As a result, bacterial infections become extremely difficult to treat.

Detailed explanation-5: -Antibiotics can treat most bacterial infections, but only a few viral infections have medications that treat them.
